The present invention relates to information processing devices, information processing methods and programs, and machine tools.

Documents in the above technical fields include Patent Document 1 and Patent Document 2. In particular, the following description is given in the lower left column 17th line to the upper left column 19th line of page 3 of Patent Document 1.

“The repaired tool and the replaced tool are preset by the tool preset device 8. The measured diameter D of the preset tool is taken into the register 13 and the measured length L is taken into the register 16 via the interface 9. The reference value Dm and the allowable value dm of the tool diameter filed in the preset request display data file 10 are taken into the registers 11 and 12, respectively.
The measured diameter D taken into the register 13 is taken into the and gates 17 and 18. The set signal from the tool preset device 8 is taken into the and gate 17.
When the set signal is taken into the and gate 17, the measured value D is taken into the comparator 19. Since the reference value Dm and the permissible value dm are taken in by the comparator 19, | D-Dm | ≤ dm in the comparator 19.
Is compared. If the measured diameter D satisfies the condition range and is OK, it is output as an OK signal and taken into the and gate 18. The measured diameter D of the and gate 18 passes through the and gate 18 and is output by an OK signal.
The comparison is performed by the comparator 19, and if the measured value D does not satisfy the condition, an alarm signal is issued via the converter 20, the operator is notified, and the tool preset device 8 is fed-banked again. The cent signal is also taken into the and gate 21.
When the set signal is taken into the and gate 21, the measured length L is taken into the comparator 23. Since the reference length Lm and the permissible value lm already stored in the registers 14 and 15 are already taken in by the comparator 23, the comparator 23 | L-Lm | <lm
Is compared. If the measured length L satisfies the condition range and is OK, it is output as an OK signal and taken into the and gate 22. By taking in the OK signal, the and gate 22 passes the actually measured length L through the and gate 22 and outputs it.
The comparison is performed by the comparator 23, and if the measured length L does not satisfy the project, an alarm signal is issued via the converter 24, notifies the operator, and is fed back to the tool preset device 8 again. "

Further, as shown in FIGS. 3 to 5, the tools are grouped by a parent number and a child number.

The determination unit 103 determines whether or not the acquired shape measurement value is within the allowable dimensional range.

The notification unit 104 notifies the determination result of the determination unit 103.

According to this embodiment, the tool information can be easily set, and the input error of the measured value can be reduced.

[Second Embodiment]
Next, the information processing apparatus 200 according to the second embodiment of the present invention will be described with reference to FIG. FIG. 2 is a diagram for explaining a functional configuration of the information processing apparatus 200 according to the present embodiment.

The information processing device 200 includes an allowable range setting unit 201, a measurement value acquisition unit 202, a determination unit 203, a notification unit 204, a change unit 205, a measurement value input unit 206, and a list generation unit 207. The information processing device 200 is incorporated in the operating device 211 attached to the machine tool 210.

The machine tool 210 is a machine tool numerically controlled by a numerical control device, and examples thereof include a milling machine, a lathe, a turning / milling machine, a milling / turning machine, a turning center, a machining center, and a multi-tasking machine. Further, the machine tool may be an additional processing machine (Additive Manufacturing Device) for additional processing of metal powder.

The machine tool 210 includes actuators (axis drive actuators, spindle drive actuators, tool exchange actuators, work / pallet exchange actuators, cooling mechanism actuators, chip transfer actuators, etc.) and sensors (temperature sensor, vibration sensor, collision sensor, optical sensor, etc.). It includes a touch sensor, etc.) and is program controlled.

The machine tool 210 includes a numerical control device having a numerical controller (NC) and a programmable logic controller (PLC) inside. The PLC controls a plurality of actuators of the machine tool 210 based on the internal PLC control logic stored in the PLC register or the like and the data or signal received from the sensor or NC. The NC controls a plurality of actuators and PLCs based on user input and manually or automatically generated machining programs (NC programs) and data or signals received from sensors.

The machine tool 210 communicates with the operating device 211 as a front-end controller and receives an operation using the operating device 211. At the same time, information such as data measured by a sensor in the machine tool 210 and a program executed by the machine tool 210 is sent to the operating device 211.

In addition to the information processing device 200, the operating device 211 includes a keyboard, push buttons, and the like as a human-machine interface that accepts input operations from the user while displaying one screen to the user. However, the present invention is not limited to this. For example, the operating device 211 may be provided with a touch panel as a human-machine interface that accepts an operation input operation from the user while displaying one or a plurality of control screens to the user. Further, the operating device 211 may separately include one or a plurality of keypads and an input device such as a button or a key as an input unit. The operating device 211 may be integrated with the external control panel of the machine tool 210.

The information processing device 200 includes a memory for storing data, an operating system, a plurality of control applications, and a processor for executing a plurality of control applications and other program modules based on the data stored in the memory. ..

The operating device 211 has a web browser and can display a web screen generated and transmitted by the web server.

The permissible range setting unit 201 has a common permissible dimensional range for a plurality of tools included in one of at least two tool groups classified by tool attributes (here, a range from a reference value minus tolerance to a reference value plus tolerance). To set. The permissible range setting unit 201 is a database that stores reference values and tolerances for each tool group as master data. The reference value is the original length of the tool included in the tool group. Tolerance is a value indicating an acceptable difference from a reference value in consideration of individual differences of the tool, and when used together with the reference value, defines an allowable dimensional range (effective range) of the shape of the tool. Specifically, the measured value obtained by measuring the shape of the tool (shape of tool diameter or tool length + wear) is compared with the set allowable dimensional range. This measured value is customarily called a correction value because it is a value for correcting the distance between the spindle and the work.

For example, when it is desired to make a product with good machining accuracy, the tolerance of the tool can be set narrow and the dimensional accuracy required for the tool to be used can be made strict. On the other hand, if the machining accuracy does not matter, the tolerance may be set wide.

The measured value acquisition unit 202 acquires the measured value obtained by measuring the shape of the tool to be attached to the machine tool. For example, the tool presetter 220 can measure the shape of the tool 230. The user can manually input the shape measurement value of the tool measured by the tool presetter 220 into the information processing device 200 by using the operating device 211. The measurement value input unit 206 passes the measurement value manually input by the user to the measurement value acquisition unit 202. The measurement value acquisition unit 202 may acquire the shape measurement value directly from the tool presetter 220.

The determination unit 203 determines whether or not the acquired shape measurement value is within the allowable dimensional range.

The notification unit 204 notifies the user of the determination result in the determination unit 203. In addition to the message display, a lamp display or an alarm sound output can be considered as the notification method.

The change unit 205 changes the permissible dimensional range set for each user's tool group based on the operation using the operating device 211. When the allowable dimensional range is changed in the changing unit 205, the notification unit 204 causes the determination unit 203 to determine again whether or not the shape measurement value of the tool set in the machine tool 210 is within the allowable dimensional range. Notify the judgment result. That is, a warning is issued for a tool having a correction value that does not fall within the changed allowable dimensional range. At this time, the notification unit 204 may give a notification prompting the replacement of the tool whose shape measurement value is not within the allowable dimensional range.

In addition, a specific unit that analyzes the machining program executed by the machine tool 210 and specifies the tool group to which the tool to be used belongs may be further provided. In that case, using the specified tool group, the reference value, the plus tolerance and the minus tolerance are read from the permissible range setting unit 201, measured by the tool presetter 220, and compared with the automatically acquired shape measurement value. It is possible to reduce typos.

The notification unit 204 notifies the identification information of the tool used having a shape measurement value that is not within the allowable dimensional range. As a result, the user can immediately determine which tool should be replaced when the allowable dimensional range is changed.

The list generation unit 207 generates a tool list indicating whether or not the tool is within the allowable dimensional range for each tool used. According to this tool list, it is possible to determine at a glance which of the plurality of tools set in the machine tool 210 is not within the allowable dimensional range.

The flow of processing using the information processing apparatus 200 will be described with reference to FIG. FIG. 3 shows the flow of processing in the scene where the shape measurement value is input when the tool to be used is replaced or newly set. In step S301, the tool number of the tool to be used is input. Since the tool number is composed of a combination of a group number and a serial number, the tool group is specified in step S303. The serial number is the serial number of the tool in the tool group.

FIG. 4 is an example of a screen 400 displaying a list of tool groups. As shown on screen 400, the tool group contains information about group number 401, tool group name 402, reference length 403 and reference diameter 404. Further, for example, when the down arrow 405 of the tool group 0001 is selected, the screen 500 shown in FIG. 5 is displayed, and by selecting the tool correction tab 501, the tool length and the tool diameter, and their respective tolerances (+) and tolerances (+) -) Can be entered and corrected. For the tool group of group number "0001", 0 is displayed before inputting the reference and tolerance (±). The tool correction tab is selected, and by inputting the reference value and tolerance (±) of the tool, the screen 1000 is displayed. In this example, 142.902 is entered as the reference value for the tool length, 0.005 is entered as the + tolerance, and -0.398 is entered as the-tolerance. Similarly, 10.000 is entered as the reference value for the tool diameter, 0.030 is entered as the + tolerance, and -0.201 is entered as the-tolerance.

One group is divided into a plurality of (here, eight) subgroups as indicated by # 1 and # 2 of reference numeral 502, and a plurality of reference values and tolerance patterns are contained in one tool group. It is configured so that can be set. For example, when the shape of the tool is an inverted T shape, the allowable dimensional range determined by the tool length, the tool diameter, and the tolerance may differ depending on which part of the tool is used for machining even if the tools are in the same group. In such a case, each allowable dimension range may be set in the subgroup. Further, a plurality of reference values and tolerances when Group 1 is used as a turning tool may be registered, and a plurality of reference values and tolerances when used as a milling tool may be registered.

Further, by changing the tab on the screen 500, general information about the tool included in the group number "0001" and information such as tool life, load monitoring, group tool, and tool model can be displayed. Here, the group number "0001" is shown as an example, but of course, a screen similar to the screen 500 can be displayed for each tool group such as the group numbers "0002" and "0003". The tool group may be distinguished by using the name of the tool type in addition to the group number "0001". Tool types include drills, milling cutters, tools, and cutters.

By moving the splitter bars 406 and 506 provided on the screen 400 and the screen 500 to the left, the transition to the screen 600 in FIG. 6 can be performed. On the screen 600, the serial number and group number 601, the tool group name 602, the tool length shape and the tool length wear 603, and the tool diameter shape and the tool diameter wear 604 are displayed for each tool set in the machine tool 210. The tool length shape and tool length wear 603, and the tool diameter shape and tool diameter wear 604 are shape measurement values. If these shape measurements do not meet the permissible dimensional range set in association with the tool group, message 605 is displayed.
That is, in step S305 of FIG. 3, the reference values and tolerances for each tool group set in the permissible range setting unit 201 are acquired, and in step S307, the input shape measurement values are acquired, and they are obtained in step S309. To compare.

If the reference value-tolerance <shape measurement value <reference value + tolerance is satisfied, the process proceeds to step S311 and the process proceeds to processing using the acquired shape measurement value. If the above relational expression is not satisfied, the process proceeds to step S313 and the message 605 is displayed.

In addition to the above inequality, the following inequality may be used for judgment.
-Tolerance <Reference value-Measured value <+ Tolerance

For example, even though the set tool is a long tool, if a short shape measurement value is set due to an input error, the machining program performs machining based on the input shape measurement value, so it interferes during execution of the machining program. Problems such as may occur. Therefore, the message is displayed as described above to avoid such a problem in advance. When the tool is changed many times, the tool is measured and the measured value is manually input each time, but even in that case, according to the present embodiment, the occurrence of the problem can be avoided by notifying the message.

Although the screen 600 shows a list of all the tools attached to the magazine of the machine tool 210, a list of selected tools and a list of sensor tools can be displayed by changing the tabs.
When the general life button 606 is selected on the screen 600 of FIG. 6, the screen 700 of FIG. 7 is displayed. The screen 700 is a screen that displays the status of each tool included in the tool group of the group number “0001” with a lamp (green or red) or the like. On the screen 700, the tool number 701, the tool name 702, the tool type 703, and whether or not it is a large-diameter tool 704 are displayed, and further, whether or not it is a spindle tool 705, the next tool 706, in use 707, skip 708, load 709, Lamps indicating the service life of 710 are displayed. In addition, the counting method (number of times of use or time of use) 711 of each tool, the remaining life of 712, and the like are also displayed.

FIG. 8 is a diagram showing another screen 800 that displays the state of each tool with a lamp or the like. On the screen 800, in addition to the items 701 to 712 of FIG. 7, the STC speed 801 is displayed, and the lamp 802 indicating the suitability of the tolerance is displayed. In the example of FIG. 8, the state of the two tools of the tool numbers “10001” and “10002” is set. Here, when the shape measurement value (correction value) of the tool with the tool number "10001" is out of the permissible range, the tolerance lamp 821 turns red, and the user needs to perform individual tool correction. Notify to. By displaying the tool status in a list in this way, it becomes easy to finally confirm whether or not there is any omission of change in a plurality of tools.

FIG. 9 shows a flow of processing for checking the shape measurement value of the set tool when the reference value or the tolerance set in the tool group is changed. When the user replaces a tool with another type of tool (a tool having a different reference length) and performs another machining, the reference value or tolerance associated with the tool group is changed. Alternatively, the tool used for finishing has worn out over time, so when using it for roughing, change the strict tolerance to a looser tolerance.

When the reference value or tolerance associated with the tool group is changed in the screen 1000 as shown in FIG. 10 in step S901, the process proceeds to step S905 to acquire the shape measurement values of a plurality of tools included in the tool group. .. Then, in step S907, it is determined whether each of the shape measurement values of the plurality of tools satisfies the reference value and the tolerance (allowable dimensional range). As a result of the determination, if a tool that does not satisfy the allowable dimensional range is found, a message 1001 is displayed. In this message 1001, the tool number "(000)" among the plurality of tools registered in the tool group of "0001" is changed by changing the permissible dimensional range of the tool (at least one of the reference value and the tolerance). It indicates that the tool of "10001" has fallen out of the permissible range (outside the effective range). Here, only one tool number is shown, but when a plurality of tools are out of the permissible range, a plurality of tool numbers are shown. The tool number consists of 8 digits, the first 4 digits indicate the serial number, and the latter 4 digits indicate the tool group. As in message 1001, the upper 0s may be omitted.

The user who sees the message 1001 can eliminate the content of the message by replacing the tool with the tool number "10001" with another tool or by re-correcting and increasing the tolerance range. If the tolerance range is set to, for example, the tolerance -0.403, the shape measurement value of the tool with the tool number "10001" is within the effective range, and the notification screen is not displayed. It can also be handled by changing the shape measurement value of the tool that is out of the effective range.

Further, for example, it may have a function of analyzing a machining program and proposing a tolerance value for each of a tool used in a rough machining process and a tool used for finishing.

FIG. 11 shows a screen 1100 displaying the permissible dimensional range of the tool group of the machine tool group number “0002”. In the screen 500 of FIG. 5, an example of a screen for displaying and changing the reference value and the tolerance of the tool length and the tool diameter is shown. The dimensions in the Y and Z directions may be input and displayed, respectively. FIG. 11 shows an example in which the rotary tool type is turning. In the case of a turning tool, the angle of the tailstock axis (B axis) and the cutting edge point number of the tool cutting edge can be input and changed.

On the other hand, when the tool group having a length of 100 is used for the work A and the tool group having a length of 50 is used for the work B the next day, or when the machining accuracy (roughing or finishing) is changed, the tool is used. It is necessary to change the allowable dimensional range (reference value and tolerance) of the group. In that case, it is possible to identify and notify the tool that does not fall within the changed allowable dimensional range, and prompt the replacement. It is efficient because the dimensional tolerance is set collectively for each type of tool. Since multiple sets of reference values and tolerance settings (8 subgroups in the above) can be memorized for each tool group, different dimensional tolerances can be set when the same type of tool is used in various ways. ..

The user is free to set the tool group. Only short tools may be grouped together, grouped by size, or grouped by type (drill, milling cutter, tool bit, cutter, etc.).

Since the reference value and tolerance can be set for each tool group, it is possible to check the suitability and unsuitability of the shape measurement value with a simpler method, and prevent the tool from interfering with the workpiece when the machining program is executed. It can be avoided.

[Second Embodiment]
11 to 22 are examples of display of operation screens of the 5-axis machine shown in FIG. 23 and the horizontal machining center shown in FIG. 26.

Inside the machine tool, there is a tool spindle to which the tool is attached, and the tool can be replaced and machined depending on the machining conditions such as rough machining and precision machining. The replaced tool is stored in the magazine. Tools stored in the magazine can be selected according to the machining conditions and mounted on the tool spindle for machining. For each tool, check the information about each tool on the operation screen, select an appropriate tool, and machine the workpiece. On the operation screen, it is possible to input a tool correction value so that the tip of the tool does not interfere with the work of the machine tool.

FIG. 11 is an example of an operation screen, and displays an image showing information on standards and tolerances related to tool correction of the tool group “0002” in the magazine tool group. For information on tool group "0002", there are tabs for General, Tool Life, Tool Compensation, Group Tools, Tool Models. In FIG. 11, the tool correction tab is selected, and a screen on which the reference value and tolerance (±) of the tool can be input for X, Y, Z, and R is displayed.
By inputting the reference value and the tolerance value as the reference dimension range, it is displayed or notified that the shape measurement value input for the tool to be used is out of the reference dimension range. As a result, it is possible to prevent the tool from interfering with the work of the machine tool or the like when the machining program (NC program) is actually executed.
Since the reference dimension range can be set individually for each tool group determined by the tool type and the like, the user's labor can be reduced. In the example of FIG. 12, the rotary tool type is a turning tool.

FIG. 12 shows a screen displaying information on the tool group of “0001”. This is the screen before inputting the tool correction standard and tolerance (±) for the tool group of "0001". The tool correction tab is selected, and the reference value and tolerance (±) of the tool correction can be input in the X-axis direction, the Y-axis direction, and the Z-axis direction. FIG. 12 shows a screen before the values are input to the tool correction reference and tolerance of the tool group of “0001”.

FIG. 13 shows a screen in which a reference and a tolerance in the Z-axis direction are input for the tool group of “0001”. In the machine tool of FIG. 13, the frame whose length is Z and whose width is the reference is the tool length, and 142.902 is input. The effective range of the correction value (shape + wear) to be input to the tool registered in the tool group is specified by the reference value and tolerance. A warning is issued if the user sets a correction value (shape measurement value) outside the effective range registered in the tool group for the tool.

Although the tolerance value of FIG. 13 is changed in FIG. 14, since all the tools registered in the tool group of “0001” can be used within the allowable range, what kind of tool is used with the changed input value. Is tolerated.

FIG. 15 has a narrower tolerance range than FIG. FIG. 13 shows a tolerance of -0.409, FIG. 14 shows a tolerance of -0.403, and FIG. 15 shows a narrower tolerance of -0.398. When the tolerance is set as shown in FIG. 15, among the tools registered in the tool group of "0001", the tool with the number 10001 is out of the tolerance range (outside the effective range). Therefore, in front of the tool correction screen of the tool group of "0001", a screen indicating that the tool of the number 10001 is out of the effective range is generated and displayed. This makes it possible to respond to the error message shown in FIG. 15 by replacing the tool number 10001 with another tool or by revising the tolerance range to increase the tolerance range. If the tolerance range is set to, for example, the tolerance -0.403, the shape measurement value of the tool with the number 10001 will be within the effective range, and the notification screen will not be displayed.

It can also be handled by removing tools that are out of the effective range. When it is desired to check the shape measurement values of a plurality of tools, a screen as shown in FIG. 16 is effective. FIG. 16 shows the status of the tools “10001” and “10002” registered in the tool groups of “0001” and “0002”. Two tools, number 10001 and number 10002, are registered. Here, as shown in the screen of FIG. 16, when the tool with the number 10001 is out of the effective range, the tolerance lamp emits red light so that the operator can easily be informed that individual tool correction needs to be performed. The screen is being generated. With the screen shown in FIG. 16, the user can easily see and intuitively know which tool information should be corrected.
Furthermore, as an application, for example, if there is a function such as NC program analysis and finishing, rough machining process and each tool are specified and tolerance values are proposed, even higher precision machining becomes possible.
