2. Description of the Related Art In the case of an aluminum sash window frame, for example, the above-mentioned frame material is used as shown in FIG.
Cutouts 201a in the upper and lower end portions of the intermediate portion 1,202,
201b and 201c are provided, and the cutouts 201 at the upper and lower ends are provided.
a, 201b, the upper and lower frames 203, 204 end portions are fitted, the middle cutout portion 201c is fitted with a horizontal frame 205 end portion, and the upper and lower frames 203, 204 end portions and the horizontal frame 205 end portions are A mounting screw 207 is screwed through a screw hole 206 provided in the wall portion 201d of each of the vertical frames 201 and 202, so that the window frame 200
Has a framework. In such a window frame 200, since the vertical and horizontal sizes are determined according to the window opening of the building,
Vertical frames 201, 202, horizontal frames 205, upper and lower frames 203, 20
In many cases, 4 are mold materials having the same cross-sectional shape and cross-sectional dimensions, and only the overall size of the framed window frame is different. In such a case, in the large window frame and the small window frame, each of the frames forming each window frame has the entire length,
The longitudinal positions of the cutouts at the end and the middle are different, but the machining dimensions of the cutouts and the screw holes formed in the cutouts, the positions of the screw holes with respect to the cutouts, etc. They are exactly the same because the dimensions do not change. Conventionally, when machining notches and screw holes on long materials, the coordinates of each notch and screw hole are entered with reference to one machining origin of the machine tool, and the machine tool and It was processed by controlling the relative positional relationship of the materials. On the other hand, although it is not a long material, N is suitable for processing many workpieces of the same shape in different positions and in different directions on the same workpiece.
As the C data creation method, the machining dimension is defined for the basic shape by an independent coordinate system, and the X, Y (and Z) directions between this local coordinate system and the machine coordinate system and the figure In the actual machining, there is a machine in which the local coordinate system is converted into the machine coordinate system to perform the machining by giving a shift amount of the rotation direction angle (JP-A-60-5).
5411).

[0003]

In the former prior art,
With one machining origin of the machine tool as a reference, a large number of notches in the long material and the coordinates of the screw hole positions related to this were input separately, and machining was performed based on this If the notch, the screw hole size, and the screw hole position relative to the notch are the same, but only the longitudinal dimension of the long material and the longitudinal position of the notch are different, There is a problem in that it is time-consuming to input such processing data because it is necessary to input and change a large number of coordinates of many processing parts each time according to length and shortness. With the latter technology, simply changing the shift amount of the independent local coordinate system and machine coordinate system,
Since NC data that can perform the same machining at different positions of the work can be obtained, it is easy to input data, but still,
According to the above technique, at least X, Y, and three directions of rotation are used.
One shift amount must be given, and for a work such as a long material that is different only in the position in the longitudinal direction, this technique also has a problem that the data input is still complicated. An object of the present invention is to provide a machining data creation method that facilitates modification of machining data for long materials having the same machining shape and different lengths, and a machining data creation device that implements the creation method. is there. Further, in the sash material, as described above, since the upper and lower frames are framed by the vertical frame, the notch size of the longitudinal ends of the upper and lower frames is not correct when the frame is assembled unless the size from the end is accurate. There is a problem that the division is not well framed. Another object of the present application is to provide a creating method capable of easily modifying processed data so as not to cause such a problem.

Unlike the combination of a general keyboard and a display, this input display means 8 is a touch panel type that can display information from the general-purpose PC 6 on the screen and can perform input to the general-purpose PC 6 from the screen in the present application. It is a thing. The machine tool 2 for machining is shown in plan view in FIG. This machine tool 2 is a vertical machining center in which a main shaft 2a faces vertically downward, and has an X-axis direction (workpiece longitudinal direction), a Y-axis direction (workpiece width direction), and a Z-axis direction (vertical direction, in FIG. 7). The main shaft 2a, that is, the tool T moves in three orthogonal directions (vertical direction). The data creation device comprises an input display means 8 and a general-purpose PC 6.

Workpieces handled by this NC control device are framed as shown in FIG. 10 to form the sash window frame 200. The left and right vertical frames 201 and 202, and the upper and lower frames 203 and 20.

The processed shape will be explained, for example, with respect to the vertical frame 201, as shown in FIG. Cutouts 201a, 201b, 201c in which the bent piece portions 201e, 201e (FIG. 8) are removed, and the vertical frame 2
In order to screw the setscrews 207 into the screw grooves of the upper and lower frames 203, 204 and the horizontal frame 205 via 01, it is composed of a large number of screw holes 206 provided in the wall portion 201d of the vertical frame 201.

In order to machine such a work, the machining shapes of the work are classified, and the basic shapes of the machining that can be performed by one tool are grouped together, and a general-purpose PC 6 is provided as several basic shape patterns. It is stored in the shape pattern storage unit 25 in the RAM. The basic shape pattern is a shape, a hole, or patterns 1, 3, 3 as shown in FIG.
After the machining of 4, 6, 11, and 12, the slots are classified into the slotter machining for performing the slotter machining on the R portion.

In the machined portion of such a work, the relative positional relationship between the notch and the screw hole is the same as long as the frame material of the mating frame is the same. Therefore, as shown in FIG. 7, the machining parts having a relative positional relationship that is not changed are grouped into left and right end machining groups 20 and 30 and an intermediate machining group 40. The actual dimensions for some basic shape patterns included in each processing group are defined by independent coordinate systems with the origin common to each processing group. That is, in the work of FIG. 7, the basic shape patterns belonging to the left end processing group 20 are pattern 1 (upper cutout), pattern 3 (lower cutout), pattern 51 (slotter processing), and pattern 63 (drilling). Yes, these are defined by a coordinate system based on an origin 21 that coincides with the machining origin of the machine, and the machining origin 21 of the machine is located in a plane including the left end face 200L of the frame material. Further, patterns 4, 6, 51, 64 belong to the right end machining group 30, and these are local with respect to an origin 31 obtained by shifting only the machining origin 21 of the machine and the coordinate in the workpiece longitudinal direction (X-axis direction). Defined in the coordinate system,
The origin 31 is located in the plane including the right end surface 200R of the frame material. Further, the intermediate processing group 40 has the pattern 1
1, 12, 51, 63 are also included, and these are also the origin 41 of the machine, which is the machining origin 21 and the work longitudinal coordinate.
Is defined in the local coordinate system based on. In the present embodiment, the intermediate machining group 40 shows only the left end reference machining group to which the shift amount SM from the origin 21 of the left end machining group 20 is given, but in addition to this, from the origin 31 of the right end machining group 30. Shift amount A
When there is an intermediate machining group (a square hole portion such as the portion 45 in FIG. 7 and a screw hole) to which is given, this is also described in a local coordinate system with another origin 46 as a reference.

A control program relating to the input / output of data shown in FIG. 3 is stored in the RAM in the general-purpose PC 6,
With this control program, processing data for the above-mentioned work is created. Each control step of the control program indicates a function realizing means, and step S3
Is a means for inputting common data (thickness, width, total length, etc.) of the mold material, and step S4 is a machining group selecting means for selecting the machining group. When the intermediate machining group 40 is selected, machining of the machine is performed. The origin shift amount SM in the X-axis direction from the origin 21 is input, and it also serves as an origin shift amount input means between coordinate systems. Of course, if the intermediate processing group has the right end processing reference group with the right end of the work as a reference, the origin shift amount A from the origin 41 of the coordinate system at the right end is input. Further, step S5 is a processing pattern selection means,
It is a means for selecting a basic shape pattern included in the selected processing group from the above-mentioned basic shape patterns. Step S7 is a dimension input means for setting the actual machining dimension including the cutting condition and the tool selection for the selected basic shape pattern. All of these inputs are performed on the screen of the touch panel 8. Further, steps S8 and S9 are data storage command means for referring to a data conversion table, which will be described later, as to where in the variable data storage section the data input from the screen is stored, and storing the data in a predetermined storage position. Further, step S14 is a transmission means for sending variable data, which will be described later, for a plurality of processing patterns (here, three patterns) to the PC 4 on the NC side prior to the processing, and step S15 is for starting NC processing on the NC side and then executing NC. It is a transmission means for transmitting the machining pattern variable data one pattern at a time until the drawing number data ends, in response to a request from the side.

In the RAM of the general-purpose PC 6, a plurality of processed data storage units 10 for each product drawing number are provided. As shown in FIG. 5, each machining data storage unit 10 includes a drawing number data storage unit 11, a common data storage unit 12 for the work of the drawing number, which machining group contains which basic shape pattern, as shown in FIG. A group management data storage unit 13 that manages and delimits processing groups, a left end processing group data storage unit 14, an intermediate processing group data storage unit 15, and a right end processing data storage unit 16 are arranged in order. Each processing group data storage unit 14, 15, 16 is composed of a plurality of variable data storage units 17 that store variable data for the basic shape pattern in association with each basic shape pattern.

The general-purpose PC 6 has a display input buffer 50 for exchanging data with the touch panel 8. A large number of data storage positions a, b, c, d, e ... Of the buffer 50 are in one-to-one correspondence with dimensions for various basic shape patterns displayed on the touch panel 8, input of various data, and display positions. The data storage position is data indicating the display position. Also, a general-purpose PC
A data conversion table 51 showing the correspondence relationship between the storage position of the buffer 50 and the data storage position in the variable data storage unit 17 is provided in the RAM 6 of FIG.
In the data conversion table 51, the data stored from the beginning in the storage position of the buffer 50 is stored in the variable data storage unit 17
From the beginning address (the beginning of the variable data is always set to the pattern type), the data size to be stored (that is, the storage position) is described by the data type code and stored in the buffer. It is associated with the storage location. Therefore, at the time of data input, the data input at a certain position on the screen in step S8 of the flowchart is stored in the corresponding storage position of the buffer 50, and the data conversion table 51 is referred to here. Thus, the data having a small data size is sequentially stored so as to divide the memory unit (16 bits) of the variable data storage unit 17 into a plurality of sections, thereby saving the storage area, that is, R
It is adapted to be stored in a form suitable for storage in the AM. Further, even when the data stored in this way is read out, the data conversion table 5 corresponding to the pattern to be read depends on which pattern is the processed pattern.
By referring to 1, the variable data is stored such that the next 4 bits of the machining pattern type data of the first 8 bits of the head address of the variable data storage unit 17 are the tool number, the next is the reference and group discrimination data. The stored information is cut out by saving the memory in the storage unit as much as possible, and the cut out data is stored in the corresponding storage position of the buffer 50 in a format suitable for display. Therefore, the data conversion table 51 prepared for each basic shape pattern should be referred to even if the structure of variable data is different, such as the arrangement order of data due to the difference in the shape of the reference shape pattern, the size of the storage area occupied by the data, and the like. As a result, data is changed between the storage format in the variable storage area and the storage format in the buffer 50. Therefore, a large number of programs for such data modification are prepared for each basic shape pattern. do not have to. The data change table 51 can be rewritten by the maintenance personal computer 52 shown in FIG. 1, so that even if a new basic shape pattern is added, a table for the added basic shape pattern can be prepared. , Data can be stored and referenced by a new pattern without modifying the program for data conversion.

Then, the display program included in the control program is described in the display command with the display position and the display content (data stored in the data storage position of the buffer 50) as parameters, so that the buffer 50 starts from the beginning. When the display position data indicated by the data storage position of the buffer 50 and the stored contents are applied to the parameters of the display program while reading sequentially, the stored data corresponding to the corresponding position on the screen is displayed. Even if the arrangement order (data structure) of the variable data is different due to the difference in the shapes of the basic shape patterns, the display programs can be made completely common.

Next, in the general-purpose NC device 3, corresponding to each of the basic shape patterns, cutting conditions, tool conditions, dimensions required to process the machining pattern, shift amount of the origin, etc. The machining program that is input as variable data and describes the data necessary for actual machining as variables has the same number as the basic shape pattern.
It is described as a macro program using IM code (G code), and these are stored in the machining program storage unit 55. Further, in the general-purpose NC device 3, whether the variable data described and transmitted by the macro program is a proper value for machining the work, that is, the Y-axis from the work width dimension given as common data Whether the depth of cut in the direction is large, the cutting depth in the Z direction is not large relative to the height of the work, or the pitch of the screw holes does not exceed the work width. A data check program 56 is provided. This determination is performed prior to processing, and if there is any data that is inconvenient for processing, the processing is stopped based on that data to prevent defective products and to alert the operator. There is.

A variable data storage buffer 60 is provided in the NC side PC 4 which mainly controls communication. The storage buffer 60 stores variable data in units of a plurality of processing patterns transmitted from the general-purpose PC 6. The control program of the general-purpose NC device 3 is shown in FIG. Step S21 is a step of determining the presence / absence of a start command, Step 2
2 is a data reading step, step 23 is a data checking step by the checking program, step S
24 is a step of applying variables to the corresponding pattern processing program, and if necessary, step of applying variable data for converting the local coordinate system to the machine coordinate system, step 25 is a step of outputting a control command to the machine, and step 26 is processing. This is an end determination step.

The control program of the NC side PC4 is shown in FIG.
(B). Step S27 is a data storage state detection step of determining whether or not the variable data in the buffer 60 has been reduced by one machining pattern as a result of being read by the general-purpose NC device 3, and step S28 is when one machining pattern is reduced. , A data request step for issuing a request for processing data for the next processing pattern to the general-purpose PC 6, step S2
Reference numeral 9 is a receiving step for receiving data from the general-purpose PC 6. In the present application, as described above, the general-purpose NC device 3 refers to the data stored in the variable data storage buffer 60,
While controlling the machine by the macro program, the NC side PC 4 requests the next data from the general purpose PC 6 while checking the reduction of the variable data, so the machine control and the data transfer are performed at the same time, and as a result, Compared to conventional devices that stop machine control when transferring data,
Since data is smoothly transferred and only the variable data is sent from the general-purpose PC 6 to the NC device 3, the amount of data can be reduced and the transfer time can be reduced as compared with the conventional method of transferring a macro program. Is shortened.

Next, the operation will be described with reference to FIGS. In data input, through steps S1 and S2, step S
The drawing number and the mold material data (thickness,
Width, total length, etc.). Next, a processing group is selected. Since there are three left end machining groups 20, right end machining groups 30, and intermediate machining groups 40 in the work of FIG. 7, a basic shape pattern belonging to the machining group is selected in step S5 in each machining group. For example, in the left end processing group 20, first, the pattern 1 is selected, the pattern is displayed on the touch panel 8, the data input and display position on the screen are touched, and the data is directly input thereto. At the time of data input, the display screen of the touch panel 8 is switched to the keyboard screen, and the input is performed from the keyboard screen. In the pattern 1, the notch dimensions A, B, C, the tool No, the reference for the machining origin 21 of the machine, whether it is not, tool data such as the tool diameter and the tool type, and cutting in each axial direction (not shown). Cutting conditions such as speed are also entered. The dimensions are input with an origin (here, coincident with the machining origin of the machine) 21 as a reference. Each data thus input is stored in the corresponding storage position of the input display buffer 50, and with reference to the data conversion table 51 of the pattern 1, the variable data storage unit for the pattern 1 of the left end processing group data storage unit 14 is stored. 17
First, the data format is changed to a format suitable for data storage, and the data is sequentially stored as described above. Data is similarly input to other processing patterns (patterns 3, 63, 51) belonging to the left end processing group 20 and stored in the left end processing group data storage unit 14 in order as shown in FIG. It Then, through step S11, the same work is repeated for the remaining processing groups 30 and 40. When selecting the intermediate machining group 40, the input of the origin shift amount SM from the machining origin 21 of the machine is prompted,
Then, dimension input is performed with the local origin 41 as a reference. This origin shift amount SM is also stored in the intermediate machining group data storage unit 15 as variable data. Thus, a plurality of processing groups 20, 3 for one drawing number
After inputting the variable data of a plurality of basic shape patterns for 0 and 40, if there is another drawing number input in step S12, the process returns to step S1 to repeat the input.

Next, a case will be described in which variable data is created for workpieces that differ only in the longitudinal data of the mold material. In step S2, the data change is selected, and in step S16, the drawing number of the work having the same variable data of the basic shape pattern of the machining group, which differs from the work to be created only in the longitudinal direction, is input from the touch panel 8. Then, the machining group described in the local coordinate system and the machining group described in the coordinate system that coincides with the machining origin 21 (here, the leftmost machining group 2
The origin shift amount in the longitudinal direction between 0) is changed, and then a new drawing number is added and added and stored in the processed data storage unit. In this way, the variable data is created for a workpiece that has the same basic shape pattern as the previously stored workpiece and machining group, and has the same variable data, and only the longitudinal relationship between the machining groups is different. Sometimes, it is only necessary to read out the previous data and change only the origin shift amount in the longitudinal direction with respect to the machining origin 21, which makes the data change extremely easy.

Next, in step S2, data transmission is selected, and in step S13, the drawing number of the work to be processed is input. As a result, the corresponding drawing number data is selected from the processed data storage unit, and the common data shown in FIG. 5, the group management data, and the subsequent processed group data are read. Taking the drawing number data 1 as an example, the processing group data is read out from the left end processing group data 20 shown in FIG. 5 in this order from the head of the pattern 1 variable data, the pattern 3 variable data, and the pattern 63 variable. Of data,
The set of three pattern variable data is transmitted to the PC 4 on the NC side. The NC-side PC 4 performs step S in FIG.
The data is received at 29 and stored later in the buffer 60.

When the general-purpose NC device 3 is activated,
In step 22 of FIG. 4A, the data in the buffer 60 is sequentially read. Since there is common data such as the total length and width of the work in the buffer 60, a data check is performed in step S23 using such common data to determine whether or not the variable data has an appropriate value. Then, the variable data is applied to the variable description part of the machining pattern program corresponding to the pattern. Then, a machine control command is issued in step S25 for each pattern. While the NC device 3 is performing the machine control in this way, the NC side PC 4 determines whether or not the variable data in the buffer 60 has decreased by one pattern, and if the variable data has decreased by one, the next pattern Request one variable data from the general-purpose PC 6. In response to this request, the general-purpose PC 6 sends the next variable data for the pattern 51. In this way, the NC device 3 is performing the machining control and at the same time, the variable patterns are sequentially changed to NC.
Since the data is sent to the side PC 4, it is not necessary to stop the processing while waiting for data as in the conventional case, and smooth processing can be performed.

Next, when the variable data of the intermediate machining group 40 is sent, since it is described in the local coordinate system other than the coordinate system that coincides with the machining origin 21, the variable data has a shift amount from the origin. SM is also taken into consideration, and in step S24, coordinate conversion from the local coordinate system to the machine coordinate system with the machining origin as a reference is performed. The right end machining group 30 is also described in the local coordinate system with the origin 31 as a reference, but before machining the right end machining group,
Based on the given total length L, the tool is moved further to the right side position from the right end of the work, and then moved to the left to bring the tool into contact with the right end face. At this time, the tool, work, work table, machine body, The circuit which is electrically closed via the spindle head detects the total length of the work from the position of the tool in the X-axis direction, and the actual size of the total length of the work is applied as the origin shift amount during the machining of the right end machining group 30. As a result, even if there is some variation in the total length of the work, the processing standard of the right end processing group 30 is the right end surface 20 of the actual work.
Since it is performed based on 0R, the depth of cut in the X-axis direction is surely guaranteed. Then, for these patterns, a machine control command is issued in step S25, and when all the machining for one drawing number is completed, step S2
The processing is completed through 6. In addition, the right end processing group 30
Alternatively, the total length L may be applied as the origin shift amount in the X-axis direction from the machining origin 21 without measuring the actual dimension, and conversion from the local coordinate system to the machine coordinate system may be performed.

[0022]

As described above, according to the present invention, in a long material such as a sash material, machining shapes whose positional relations are invariant to each other are grouped into a left and right end machining group and an intermediate machining group of the long material. By dividing, the one coordinate system of the end machining group is made to coincide with the machine coordinate system, and each machining group is defined by the local coordinate system based on different origins that differ only in the longitudinal coordinate of the long material. Since the origin shift amount in the longitudinal direction between the coordinate system that matches the coordinate system and other coordinate systems is given to determine the machining position of each machining group, it is possible to perform intermediate machining from the end of the long material. When setting data for workpieces with different distances to the group, only the origin shift amount needs to be changed and input.
The data change operation is extremely easy as compared with the case where the rotation direction and three shift data are required. In addition, in the case where the actual length of the long material is applied to the distance between the coordinate system of the end machining group that does not include the machine origin and the end machining group that includes the machine origin, when machining with that machining data, The processing shapes of the left and right edge processing groups are performed on the basis of the end faces, and even if there is a cutting error in the length of the long material, there is no error in the cutting amount from the end surface.
When assembled as a frame, it has the advantage of being assembled correctly. Also, once the dimension data of the left and right, the intermediate processing group, and the origin shift amount between each coordinate system are input for a long material to which one drawing number is added, these data are stored together in the drawing number unit. Since it was done, when trying to process a long material of a certain drawing number, just enter the drawing number,
There is an advantage that the machining data necessary for machining can be provided to the NC device, the setup change can be extremely facilitated, and the machining efficiency can be improved.
