However, in the technique described in Patent Document 1, even if the machining conditions can be efficiently derived based on the machining state, it is not possible to manually stop the machine tool and adjust or replace the tool at that time. There is a problem that it is necessary to record manually and it takes time and effort. In addition, if there is a recording omission, it becomes difficult to investigate which tool has been adjusted and how long it has lasted until it is replaced.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a diagnostic device, a diagnostic system, a diagnostic method and a program capable of easily recording information about adjusting or replacing a tool. And.

In order to solve the above-mentioned problems and achieve the object, the present invention has a first acquisition unit that acquires detection information of the physical quantity detected from a detection unit that detects a physical quantity of the tool of the target device, and the first acquisition unit. The measurement unit that measures the degree of wear of the tool from the detection information acquired by the acquisition unit and the degree of wear measured by the measurement unit after the target device is stopped and restarted satisfy a predetermined condition. The relationship between the first determination unit for determining whether or not, the third acquisition unit for acquiring the number of times of machining by the tool from the target device, the degree of wear, and the number of times of machining acquired by the third acquisition unit. A second setting unit that sets the ranking of the wear degree in a predetermined stage by learning, and at least the wear degree set by the second setting unit as the predetermined condition by the first determination unit. When it is determined that there is a change in the rank of the tool, a writing unit for writing a first log indicating that the work has been performed on the tool is provided in the storage unit.

(Log recording process)
FIG. 6 is a flowchart showing an example of the operation of the log recording process of the first embodiment. FIG. 7 is a diagram showing an example of a dialog displayed in a pop-up in the first embodiment. FIG. 8 is a diagram showing an example of a log at the time of tool adjustment according to the first embodiment. FIG. 9 is a diagram showing an example of a log at the time of tool change according to the first embodiment. The log recording process of the diagnostic apparatus 100 according to the present embodiment will be described with reference to FIGS. 6 to 9.

<Step S11>
The numerical control unit 201 of the processing machine 200 causes the drive control unit 203 to stop the machining operation by the drive unit 204. The numerical control unit 201 transmits the context information indicating that the machining operation by the drive unit 204 has stopped to the first receiving unit 101a of the diagnostic apparatus 100 via the communication control unit 202.

The machining information acquisition unit 102 of the diagnostic apparatus 100 acquires context information received by the first receiving unit 101a indicating that the machining operation by the specific tool has stopped. The log writing unit 112 records the contents of the context information acquired by the processing information acquisition unit 102 in the storage unit 108 as a log in chronological order. For example, when machining with the tool "drill 1" is stopped, the log writing unit 112 associates the date and time when machining was stopped with the fact that machining with "drill 1" was stopped, as shown in FIG. , A log (an example of a second log) is recorded in the storage unit 108.

Then, the process proceeds to step S12.

<Step S12>
When the operator confirms that the machining operation by the machining machine 200 has stopped, the operator adjusts the position of the tool of the drive unit 204 or replaces the tool. Then, the process proceeds to step S13.

<Step S13>
After adjusting or exchanging the tools, the operator starts the processing machine 200 and restarts the processing operation. Then, the process proceeds to step S14.

<Step S14>
The detection unit 211 detects the physical quantity generated by the tool of the drive unit 204 that has restarted the machining operation, and outputs the detected physical quantity information as detection information (sensor data) to the second receiving unit 101b of the diagnostic apparatus 100. The operation determination unit 106 determines that the machining operation has been restarted based on the context information received by the first reception unit 101a. After the operation determination unit 106 determines that the machining operation of the processing machine 200 has been restarted, the measuring unit 104 determines the degree of wear of the tool of the processing machine 200 based on the detection information received by the second receiving unit 101b. To measure. The wear determination unit 107 determines how much the degree of wear has changed. When the degree of wear is lowered by a predetermined threshold value or more (step S14: "lowers"), the process proceeds to step S15, and when the degree of wear is 0 (step S14: "becomes 0"), the process proceeds to step S16. If an unexpected value such as an increase in the degree of wear is shown (step S14: “other than that”), the process proceeds to step S17.

<Step S15>
When the wear determination unit 107 determines that the degree of wear has dropped by a predetermined threshold value or more, the pop-up display control unit 110b presumes that the tool has been adjusted, and the adjustment confirmation dialog 501 (first dialog) as shown in FIG. (Example) is popped up on the display unit 111. Then, the process proceeds to step S18.

<Step S16>
When the wear determination unit 107 determines that the degree of wear is 0, the pop-up display control unit 110b presumes that the tool has been replaced, and the replacement confirmation dialog 502 (second dialog) as shown in FIG. (Example) is popped up on the display unit 111. Then, the process proceeds to step S18.

<Step S17>
When the wear determination unit 107 shows an unexpected value of the wear degree, the pop-up display control unit 110b displays a dialog indicating, for example, that the wear degree is abnormal as a process when the wear degree is abnormal. Pop-up display on 111. This ends the logging process.

When the wear degree determination unit 107 shows an unexpected value, the log writing unit 112 may further write a log indicating that the wear degree is abnormal in the storage unit 108.

<Step S18>
The operator confirms the dialog (adjustment confirmation dialog 501 or replacement confirmation dialog 502) displayed on the display unit 111, and inputs a desired operation via the input unit 109. Then, the process proceeds to step S19.

<Step S19>
For example, as shown in FIG. 7, when the adjustment confirmation dialog 501 is displayed on the display unit 111 and the operator presses the “Yes” button via the input unit 109, the log writing unit 112 Is recorded in the storage unit 108 as a log (first log) in association with the date and time when the tool was adjusted and the “☆ adjustment” to the effect that the tool was adjusted, as shown in FIG. Then, the pop-up display control unit 110b closes the adjustment confirmation dialog 501. In addition, "☆" indicates that it is a log about adjustment or replacement of a tool.

On the other hand, when the adjustment confirmation dialog 501 is displayed on the display unit 111 and the operator presses the "No" button via the input unit 109, the pop-up display control unit 110b displays the dialog of the display unit 111. The display of is changed from the adjustment confirmation dialog 501 to the replacement confirmation dialog 502. Then, when the replacement confirmation dialog 502 is displayed on the display unit 111 and the operator presses the "Yes" button via the input unit 109 due to the replacement of the tool instead of the adjustment, the log is displayed. As shown in FIG. 9, the writing unit 112 records in the storage unit 108 as a log (first log) in association with the date and time when the tool was replaced and the “☆ replacement” indicating that the tool was replaced. Then, the pop-up display control unit 110b closes the replacement confirmation dialog 502. On the other hand, when the replacement confirmation dialog 502 is displayed on the display unit 111 and the operator presses the "No" button via the input unit 109, the log writing unit 112 does not record the log. , The pop-up display control unit 110b closes the replacement confirmation dialog 502.

Further, as shown in FIG. 7, when the replacement confirmation dialog 502 is displayed on the display unit 111 and the operator presses the “Yes” button via the input unit 109, the log writing unit 112 Is recorded in the storage unit 108 as a log (first log) in association with the date and time when the tool was replaced and the “☆ replacement” indicating that the tool was replaced, as shown in FIG. Then, the pop-up display control unit 110b closes the replacement confirmation dialog 502. On the other hand, when the replacement confirmation dialog 502 is displayed on the display unit 111 and the operator presses the "No" button via the input unit 109, the log writing unit 112 does not record the log. , The pop-up display control unit 110b closes the replacement confirmation dialog 502.

This ends the logging process.

In the above description of step S19, when the "No" button is pressed in the adjustment confirmation dialog 501, the transition is made to the exchange confirmation dialog 502, but the present invention is not limited to this. For example, when the "No" button is pressed in the adjustment confirmation dialog 501, the transition to the exchange confirmation dialog 502 may not be performed and the log may not be recorded. Alternatively, if the "No" button is transitioned while the replacement confirmation dialog 502 is displayed, the transition may be made to the adjustment confirmation dialog 501.

The log recording process by the diagnostic apparatus 100 is performed according to the flow of steps S11 to S19 described above.

As described in steps S13 to S16 described above, when the machining operation by the processing machine 200 is restarted after the operator adjusts or replaces the tool, it is based on the change in the degree of wear measured by the measuring unit 104. The adjustment confirmation dialog 501 or the replacement confirmation dialog 502 is displayed, but the present invention is not limited to this. That is, after the operator adjusts or replaces the tool, the measuring unit 104 can measure the degree of wear even if the machining operation by the processing machine 200 is not restarted, and the wear determining unit 107 determines the change in the degree of wear. If the configuration is such that the above can be performed, the adjustment confirmation dialog 501 or the replacement confirmation dialog 502 may be displayed before the machining operation is restarted.

As described above, when the machining of the machining machine 200 is stopped and the machining is restarted, if the measured degree of wear satisfies a predetermined condition, a dialog for confirming whether the tool has been adjusted or replaced is displayed in a pop-up, which is easy for the operator. The fact that the tool has been adjusted or replaced by various operation inputs is recorded as a log. As a result, when adjusting or replacing the tool, it is not necessary to manually record it, and the tool is adjusted or replaced by performing a simple operation on the dialog displayed in the pop-up for confirmation. The log can be easily recorded.

(Modification example)
In the first embodiment described above, the change in the degree of wear measured after resuming machining is determined, and based on the determination result, it is determined whether to display the adjustment confirmation dialog in a pop-up or the replacement confirmation dialog in a pop-up. It was working. In this modification, after resuming machining, the pop-up display control unit 110b does not estimate whether the tool has been adjusted or replaced, and when the degree of wear changes by a predetermined value, the tool is sent to the operator. The operation of displaying a dialog for directly determining whether to adjust or replace the device will be described.

FIG. 10 is a diagram showing an example of a dialog displayed in a pop-up in the modified example of the first embodiment. With reference to FIG. 10, a dialog that pops up when the degree of wear is reduced by adjusting or replacing the tool in this modification will be described.

In this modification, when the wear determination unit 107 determines in step S14 of FIG. 6 that the degree of wear has dropped by, for example, a predetermined threshold value or more (an example of a predetermined condition), the pop-up display control unit 110b , It is presumed that the tool has been adjusted or replaced, and the adjustment / replacement confirmation dialog 503 (an example of the third dialog) as shown in FIG. 10 is popped up on the display unit 111.

Then, in step S18 shown in FIG. 6 described above, the operator confirms the adjustment / replacement confirmation dialog 503 displayed on the display unit 111, and inputs a desired operation via the input unit 109.

In step S19 shown in FIG. 6 above, for example, when the adjustment / replacement confirmation dialog 503 is displayed as shown in FIG. 10, the operator presses the “adjustment” button via the input unit 109. In this case, as shown in FIG. 8 above, the log writing unit 112 records the adjustment date and time and the adjustment “☆ adjustment” in association with each other in the storage unit 108 as a log.

Further, when the adjustment / replacement confirmation dialog 503 is displayed on the display unit 111 and the operator presses the "replace" button via the input unit 109, the log writing unit 112 has the above-mentioned figure. As shown in 9, the date and time when the tool was replaced and the fact that the tool was replaced "☆ replacement" are associated with each other and recorded in the storage unit 108 as a log.

Further, when the adjustment / replacement confirmation dialog 503 is displayed on the display unit 111 and the operator presses the "No" button via the input unit 109, the log writing unit 112 records the log. Instead, the pop-up display control unit 110b closes the adjustment / replacement confirmation dialog 503.

As described above, when the processing machine 200 is started after the tool is adjusted or replaced by the operator and the processing operation is restarted, the wear determination unit 107 determines that the degree of wear is, for example, a predetermined threshold value. If it is determined that the value has decreased by the above, the adjustment / replacement confirmation dialog 503 is displayed, and the operator is directly confirmed whether the adjustment or replacement is performed. This also means that when adjusting or replacing the tool, there is no need to manually record it, and the tool has been adjusted or replaced by performing a simple operation on the dialog that pops up for confirmation. You can easily record the log of.

When the wear determination unit 107 determines, for example, that the degree of wear has dropped by a predetermined threshold value or more, the pop-up display control unit 110b presumes that the tool has been adjusted or replaced, and displays the adjustment / replacement confirmation dialog 503. The display unit 111 is supposed to display a pop-up display, but the present invention is not limited to this. For example, when the degree of wear is increased by the wear determination unit 107, or when the degree of wear is decreased even if it is less than a predetermined threshold value, the pop-up display control unit 110b causes the display unit 111 to pop-up display the adjustment / replacement confirmation dialog 503. May be. As a result, even if the tool is adjusted or replaced, but there is no expected change in the degree of wear due to some defect (for example, a malfunction of the work or a malfunction of the detection unit 211), the tool is adjusted or replaced. It is possible to record the fact that it has been done as a log.

[Second Embodiment]
The diagnostic system according to the second embodiment will be described focusing on the differences from the diagnostic system according to the first embodiment. In the first embodiment, the wear degree of the tool is measured regardless of the number of times of machining, and when the wear degree changes before and after the machining operation, an adjustment confirmation dialog or a replacement confirmation dialog is displayed. In the present embodiment, initial learning is performed to learn the relationship between the degree of wear and the number of times of machining, the degree of wear is ranked into predetermined stages, and when the rank changes before and after the machining operation, an adjustment confirmation dialog or The operation of displaying the replacement confirmation dialog will be described. The overall configuration of the diagnostic system and the hardware configuration of the processing machine and the diagnostic apparatus are the same as those described in the first embodiment.

(Configuration and operation of functional blocks of diagnostic system)
FIG. 11 is a diagram showing an example of the configuration of the functional block of the diagnostic system according to the second embodiment. FIG. 12 is a graph showing an example of the relationship between the number of times of processing and the degree of wear. The configuration and operation of the functional blocks of the diagnostic system according to the present embodiment will be described with reference to FIGS. 11 and 12. The configuration and operation of the functional block of the processing machine 200 are the same as those described in the first embodiment.

As shown in FIG. 11, the diagnostic apparatus 100a pops up the communication control unit 101, the processing information acquisition unit 102 (second acquisition unit), the processing number acquisition unit 103 (third acquisition unit), the measurement unit 104, and the measurement unit 104. Display setting unit 105, operation determination unit 106 (second determination unit), wear determination unit 107 (first determination unit, determination unit), storage unit 108, input unit 109, display control unit 110, and display. It has a unit 111, a log writing unit 112 (writing unit), and a wear rank setting unit 113 (second setting unit). The communication control unit 101, the machining information acquisition unit 102, the machining count acquisition unit 103, the measurement unit 104, the operation determination unit 106, the wear determination unit 107, the input unit 109, the pop-up display control unit 110b, the display unit 111, and the log document. The operation of the recess 112 is the same as that described in the first embodiment.

The wear rank setting unit 113 performs initial learning to learn the relationship between the number of times of machining and the degree of wear based on the number of machining times acquired by the number of machining number acquisition unit 103 and the degree of wear of the tool measured by the measuring unit 104. It is a functional unit that sets the degree of wear to rank in a predetermined stage. When the tool of the drive unit 204 is replaced with a new type or the like in the processing machine 200, the relationship between the number of times the tool is processed and the degree of wear is unknown. Therefore, after the tool is replaced, the machining operation is repeated until the number of times the tool is considered to be the limit of the number of machining operations (hereinafter, may be referred to as "upper limit value of the number of times"), and as shown in FIG. 12, the number of machining operations. It is desirable to perform a process to learn the relationship between and the degree of wear. Here, the upper limit of the number of times may be obtained, for example, based on the relationship between the characteristics of the material of the tool and the degree of wear of other tools. Alternatively, the initial learning may be performed by setting the number of times until the tool is damaged by the machining operation as the upper limit of the number of times. However, when a tool is damaged, it is safe for workers, etc., assuming that a part of the damaged tool will scatter, or that the jig fixing the tool will be damaged or misaligned. It is assumed that it is sufficiently secured.

As a result of the initial learning, the wear rank setting unit 113 obtains the relationship between the number of times of machining and the degree of wear as shown in FIG. 12, and sets the degree of wear at a predetermined stage (“wear rank 1” to “wear” in FIG. 12). Rank 3 "). The graph showing the relationship between the number of machining times and the degree of wear shown in FIG. 12 schematically shows that the degree of wear increases linearly, but the physical characteristics of the tool are not limited to this. The shape of the graph as a result of the initial learning differs depending on the shape and the like. Further, in FIG. 12, the ranking is divided into three stages and the rank width is also set at equal intervals, but the present invention is not limited to this, and the number of rankings and the rank width may be freely set.

The wear rank setting unit 113 is realized by, for example, a program that operates on the CPU 61 shown in FIG.

The storage unit 108 contains various information necessary for the diagnostic function of the diagnostic device 100a, the content of the initial learning performed by the wear rank setting unit 113, the content of the predetermined ranking of the set wear degree, and the processing machine 200. It is a functional unit that stores logs and the like showing records such as machining status, tool adjustment and replacement. The storage unit 108 is realized by, for example, the auxiliary storage device 68 shown in FIG.

The pop-up display setting unit 105 is a functional unit that sets under what conditions the adjustment confirmation dialog or the replacement confirmation dialog is pop-displayed. For example, the pop-up display setting unit 105 may set the pop-up display conditions based on the operation input by the operator via the input unit 109. For example, the pop-up display setting unit 105 stops the machining operation of the machining machine 200, adjusts or replaces the tool, then starts the machining operation, and the wear determination unit 107 shifts to a wear rank with a low degree of wear (for example,). , "Transition from" wear rank 3 "to" wear rank 2 "), the adjustment confirmation dialog is displayed in a pop-up, and the transition to the wear rank with the lowest degree of wear (for example, from" wear rank 3 "to" wear rank 1 "). If a transition is made), a condition may be set to display a replacement confirmation dialog in a pop-up. The pop-up display setting unit 105 is realized by, for example, a program running on the CPU 61 shown in FIG.

The wear display control unit 110a of the display control unit 110 is based on, for example, the degree of wear of the tool measured by the measurement unit 104 and the relationship between the number of machining times initially learned by the wear rank setting unit 113 and the degree of wear. This is a functional unit that displays at least one of the tool wear ranks and the like on the display unit 111. The wear display control unit 110a may display on the display unit 111, for example, that when the difference between the number of times of machining and the upper limit of the number of times is equal to or less than a predetermined value, a warning or a tool replacement is urged. Good.

The communication control unit 101, the machining information acquisition unit 102, the machining count acquisition unit 103, the measurement unit 104, the pop-up display setting unit 105, the operation determination unit 106, the wear determination unit 107, the display control unit 110, and the log document shown in FIG. The embedding unit 112 and the wear rank setting unit 113 may be realized by causing the CPU 61 shown in FIG. 3 to execute the program as described above, that is, by software or by hardware such as an IC. However, it may be realized by using software and hardware together.

Further, each functional unit of the diagnostic apparatus 100a shown in FIG. 11 conceptually shows a function, and is not limited to such a configuration. For example, a plurality of functional units shown as independent functional units in FIG. 11 may be configured as one functional unit. On the other hand, the function of one functional unit in FIG. 11 may be divided into a plurality of functions and configured as a plurality of functional units.

As described above, the initial learning to learn the relationship between the degree of wear and the number of times of machining is performed, the degree of wear is ranked into predetermined stages, and the adjustment confirmation dialog or the adjustment confirmation dialog is performed based on the change in the wear rank before and after the machining operation. The exchange confirmation dialog is to be displayed. As a result, the current wear rank can be grasped, and the next tool adjustment or replacement time can be easily grasped in relation to the current number of times of machining.

[Third Embodiment]
The diagnostic system according to the third embodiment will be described focusing on the differences from the diagnostic system according to the first embodiment. In the first embodiment, the tool is adjusted or replaced by the manual operation of the operator based on the adjustment confirmation dialog or the replacement confirmation dialog displayed according to the pop-up display conditions set by the pop-up display setting unit 105.

The operations of the unit 110a and the display unit 111 are the same as those described in the first embodiment.

When the operation mode is set to the manual mode by the mode setting unit 114, the pop-up display control unit 110b of the display control unit 110 performs an adjustment confirmation dialog or replacement confirmation according to the pop-up display conditions set by the pop-up display setting unit 105. This is a functional unit that displays a dialog on the display unit 111.

When the operation mode is set to the manual mode by the mode setting unit 114, the log writing unit 112 logs that the tool has been adjusted or replaced according to the contents input through the adjustment confirmation dialog or the replacement confirmation dialog. It is a functional unit that writes (records) in the storage unit 108. Further, when the operation mode of the log writing unit 112 is set to the automatic mode by the mode setting unit 114, the tool is adjusted or replaced according to the change in the degree of wear of the tool determined by the wear determination unit 107. It is presumed that the tool has been adjusted or replaced, and the fact is written (recorded) in the storage unit 108 as a log. The log writing unit 112 is realized by, for example, a program running on the CPU 61 shown in FIG.

The mode setting unit 114 is a functional unit that sets the operation mode of the processing machine 200 to a manual mode or an automatic mode. The mode setting unit 114 sets the operation mode according to, for example, an operation by the operator via the input unit 109. The mode setting unit 114 is realized by, for example, a program running on the CPU 61 shown in FIG.

Further, each functional unit of the diagnostic apparatus 100b shown in FIG. 13 conceptually shows a function, and is not limited to such a configuration. For example, a plurality of functional units shown as independent functional units in FIG. 13 may be configured as one functional unit. On the other hand, the function of one functional unit in FIG. 13 may be divided into a plurality of functions and configured as a plurality of functional units.

(Log recording process)
FIG. 14 is a flowchart showing an example of the operation of the log recording process of the third embodiment. The log recording process of the diagnostic apparatus 100b according to the present embodiment will be described with reference to FIG.

<Steps S31 to S34>
The processes of steps S31 to S34 are the same as the processes of steps S11 to S14 shown in FIG. 6, respectively. When the degree of wear is lowered by a predetermined threshold value or more (step S34: "lowers"), the process proceeds to step S35, and when the degree of wear is 0 (step S34: "becomes 0"), the process proceeds to step S37. If it shifts and shows an unexpected value such as an increase in wear degree (step S34: “other than that”), it shifts to step S40.

<Step S35>
When the operation mode is set to the manual mode by the mode setting unit 114 (step S35: manual), the process proceeds to step S36, and when the operation mode is set to the automatic mode (step S35: automatic), the process proceeds to step S41.

<Step S36>
When the wear determination unit 107 determines that the degree of wear has dropped by a predetermined threshold value or more, the pop-up display control unit 110b presumes that the tool has been adjusted, and displays the adjustment confirmation dialog 501 as shown in FIG. 7 on the display unit 111. Pops up. Then, the process proceeds to step S39.

<Step S37>
When the operation mode is set to the manual mode by the mode setting unit 114 (step S37: manual), the process proceeds to step S38, and when the operation mode is set to the automatic mode (step S37: automatic), the process proceeds to step S41.

<Step S38>
When the wear determination unit 107 determines that the degree of wear is 0, the pop-up display control unit 110b presumes that the tool has been replaced, and displays the replacement confirmation dialog 502 as shown in FIG. 7 on the display unit 111. Pops up. Then, the process proceeds to step S39.

<Steps S39 and S40>
The processes of steps S39 and S40 are the same as the processes of steps S18 and S17 shown in FIG. 6, respectively.

<Step S41>
When the operation mode is the manual mode, the log writing unit 112 and the pop-up display control unit 110b perform the same processing as the processing in step S19 shown in FIG.

On the other hand, when the operation mode is the automatic mode, the log writing unit 112 estimates that the tool has been adjusted when the wear determination unit 107 determines in step S34 that the degree of wear has dropped by a predetermined threshold value or more, and the tool. The date and time of the adjustment and the adjustment "☆ adjustment" are associated with each other and recorded in the storage unit 108 as a log (see FIG. 8). Further, when the wear determination unit 107 determines that the degree of wear is 0 in step S34, the log writing unit 112 presumes that the tool has been replaced, and replaces the tool with the date and time when the tool was replaced. In association with the effect "☆ exchange", it is recorded in the storage unit 108 as a log (see FIG. 9).

This ends the logging process.

According to the flow of steps S31 to S41 described above, the log recording process by the diagnostic apparatus 100b is performed.

As described above, in the present embodiment, it is possible to switch between the manual mode and the automatic mode as the operation mode, and in the automatic mode, the pop-up display and the operation input work by the operator are skipped and recorded in the log. As a result, when adjusting or changing the tool, it is not necessary to record manually, and in the automatic mode, there is no need to perform a simple operation on the dialog displayed in the pop-up, and the tool is adjusted or changed. The log can be easily recorded.

[Fourth Embodiment]
The diagnostic system according to the fourth embodiment will be described focusing on the differences from the diagnostic system according to the first embodiment. In the first embodiment, after the machining machine 200 is stopped, the tool is adjusted or replaced, and only the fact that the tool is adjusted or replaced is recorded in the log by a simple operation on the displayed dialog. .. However, instead of recording only the adjustment or replacement of the tool, further record comments such as how the adjustment was made or the reason other than the increase in wear for the purpose of adjustment or replacement. This is often more useful from the viewpoint of maintenance of the processing machine 200. In the present embodiment, when the machining machine 200 is stopped and the tool is adjusted or replaced, not only the fact that the tool has been adjusted or replaced but also the corresponding operation that can be recorded by adding a comment explain. The overall configuration of the diagnostic system, the hardware configuration of the processing machine and the diagnostic apparatus, and the configuration of the functional blocks of the diagnostic system are the same as those described in the first embodiment.

(Pop-up display operation)
FIG. 15 is a diagram illustrating at what timing the pop-up display is performed in the fourth embodiment. The outline of the operation of the pop-up display of the present embodiment will be described with reference to FIG.

As described above, the pop-up display setting unit 105 sets under what conditions the adjustment confirmation dialog or the replacement confirmation dialog is pop-displayed. In the present embodiment, for example, as shown in FIG. 15, the pop-up display setting unit 105 stops the machining operation of the machining machine 200, adjusts or replaces the tool (“blade” in FIG. 15), and then machining. When the operation is started and the wear determination unit 107 determines that the degree of wear has dropped by a predetermined threshold value or more, an adjustment confirmation dialog is displayed in a pop-up, and a comment dialog accompanying the dialog is displayed to make a memo (comment). It is assumed that the condition that the input is possible is set. Further, as shown in FIG. 15, the pop-up display setting unit 105 pops up a replacement confirmation dialog when the wear determination unit 107 determines that the wear degree is 0, and further, a comment dialog accompanying the pop-up confirmation dialog. It is assumed that the condition is set so that a memo (comment) can be input by displaying.

The pop-up display control unit 110b causes the display unit 111 to display the adjustment confirmation dialog, the replacement confirmation dialog, and the comment dialog according to the pop-up display conditions set by the pop-up display setting unit 105.

(Log recording process)
FIG. 16 is a flowchart showing an example of the operation of the log recording process of the fourth embodiment. FIG. 17 is a diagram showing an example of a dialog displayed in a pop-up in the fourth embodiment. FIG. 18 is a diagram showing an example of a log at the time of tool adjustment according to the fourth embodiment. FIG. 19 is a diagram showing an example of a log at the time of tool change according to the fourth embodiment. The log recording process of the diagnostic apparatus 100 according to the present embodiment will be described with reference to FIGS. 16 to 19.

<Steps S51 to S54>
The processes of steps S51 to S54 are the same as the processes of steps S11 to S14 shown in FIG. 6, respectively. When the degree of wear is lowered by a predetermined threshold value or more (step S54: "lowers"), the process proceeds to step S55, and when the degree of wear is 0 (step S54: "becomes 0"), the process proceeds to step S56. If it shifts and shows an unexpected value such as an increase in wear degree (step S54: “other than that”), it shifts to step S57.

<Step S55>
When the wear determination unit 107 determines that the degree of wear has dropped by a predetermined threshold value or more, the pop-up display control unit 110b presumes that the tool has been adjusted, and displays the adjustment confirmation dialog 501 as shown in FIG. 17 on the display unit 111. Pops up. Then, the process proceeds to step S58.

<Step S56>
When the wear determination unit 107 determines that the degree of wear is 0, the pop-up display control unit 110b presumes that the tool has been replaced, and displays the replacement confirmation dialog 502 as shown in FIG. 17 on the display unit 111. Pops up. Then, the process proceeds to step S58.

<Step S57>
The process of step S57 is the same as that of step S17 shown in FIG.

<Step S58>
The operator confirms the dialog (adjustment confirmation dialog 501 or replacement confirmation dialog 502) displayed on the display unit 111, and inputs a desired operation via the input unit 109. Then, the process proceeds to step S59.

<Step S59>
For example, as shown in FIG. 17, when the adjustment confirmation dialog 501 is displayed on the display unit 111 and the operator presses the “Yes” button via the input unit 109, the log writing unit 112 Is recorded in the storage unit 108 as a log in association with the date and time when the tool was adjusted and the “☆ adjustment” to the effect that the tool was adjusted, as shown in FIG. Then, the pop-up display control unit 110b shifts the display of the dialog of the display unit 111 from the adjustment confirmation dialog 501 to the comment dialog 511. In addition, "☆" indicates that it is a log about adjustment or replacement of a tool.

On the other hand, when the adjustment confirmation dialog 501 is displayed on the display unit 111 and the operator presses the "No" button via the input unit 109, the pop-up display control unit 110b displays the dialog of the display unit 111. The display of is changed from the adjustment confirmation dialog 501 to the replacement confirmation dialog 502. Then, when the replacement confirmation dialog 502 is displayed on the display unit 111 and the operator presses the "Yes" button via the input unit 109 due to the replacement of the tool instead of the adjustment, the log is displayed. As shown in FIG. 19, the writing unit 112 records in the storage unit 108 as a log in association with the date and time when the tool was replaced and the “☆ replacement” indicating that the tool was replaced. Then, the pop-up display control unit 110b shifts the display of the dialog of the display unit 111 from the exchange confirmation dialog 502 to the comment dialog 511. On the other hand, when the replacement confirmation dialog 502 is displayed on the display unit 111 and the operator presses the "No" button via the input unit 109, the log writing unit 112 does not record the log. , The pop-up display control unit 110b shifts the display of the dialog of the display unit 111 from the exchange confirmation dialog 502 to the comment dialog 512.

Further, as shown in FIG. 17, when the replacement confirmation dialog 502 is displayed on the display unit 111 and the operator presses the “Yes” button via the input unit 109, the log writing unit 112 Is recorded in the storage unit 108 as a log in association with the date and time when the tool was replaced and the “☆ replacement” indicating that the tool was replaced, as shown in FIG. Then, the pop-up display control unit 110b shifts the display of the dialog of the display unit 111 from the exchange confirmation dialog 502 to the comment dialog 511. On the other hand, when the replacement confirmation dialog 502 is displayed on the display unit 111 and the operator presses the "No" button via the input unit 109, the log writing unit 112 does not record the log. , The pop-up display control unit 110b shifts the display of the dialog of the display unit 111 from the exchange confirmation dialog 502 to the comment dialog 512.

Then, the process proceeds to step S60.

<Step S60>
As shown in FIG. 17, when the comment dialog 511 or the comment dialog 512 is displayed on the display unit 111, the operator inputs a comment for adjusting or replacing the tool via the input unit 109. Then, the process proceeds to step S61.

<Step S61>
As shown in FIG. 17, when the comment dialog 511 is displayed on the display unit 111 and the operator presses the “OK” button via the input unit 109, the log writing unit 112 is shown in FIG. As shown in 18 and 19, the date and time when the tool was adjusted or replaced, the fact that the tool was adjusted or replaced, and the input comment regarding the adjustment or replacement are associated and recorded in the storage unit 108 as a log. For example, in the example of FIG. 18, it is shown that the comment "☆ Adjust the depth and restart machining" was recorded as a log in association with the effect of adjustment. Further, in the example of FIG. 19, it is shown that the comment "☆ Replaced because the blade was missing" was recorded as a log in association with the fact of replacement. Then, the pop-up display control unit 110b closes the comment dialog 511.

On the other hand, when the comment dialog 511 is displayed on the display unit 111 and the operator presses the "Cancel" button via the input unit 109, the log writing unit 112 can record the comment log. Instead, the pop-up display control unit 110b closes the comment dialog 511.

Further, as shown in FIG. 17, when the comment dialog 512 is displayed on the display unit 111 and the operator presses the "OK" button via the input unit 109, the log writing unit 112 , The date and time when the tool was adjusted or replaced, and the fact that the adjustment or replacement was performed are associated with the input comments other than the adjustment or replacement work, and recorded in the storage unit 108 as a log. Then, the pop-up display control unit 110b closes the comment dialog 512.

On the other hand, when the comment dialog 512 is displayed on the display unit 111 and the operator presses the "Cancel" button via the input unit 109, the log writing unit 112 can record the comment log. Instead, the pop-up display control unit 110b closes the comment dialog 512.

This ends the logging process. According to the flow of steps S51 to S61 described above, the log recording process by the diagnostic apparatus 100 is performed.

As described above, in the present embodiment, when the machining machine 200 is stopped and the tool is adjusted or replaced, not only the fact that the tool is adjusted or replaced but also a comment is additionally recorded accordingly. It is supposed to be possible.
