Then, the three-dimensional data D10 and the like of the dead area are stored.

However, the inside of the memory ME does not necessarily have to be constructed as in the illustrated embodiment, but may be constructed in other ways, and if necessary,
For example, a program for performing stress analysis of the three-dimensional data D1 of the work may be provided.

Then, in a state where the control device C1 is operated by any of the CAD program PR1, the jig program PR2, and the CAM program PR3, the designer operates the computer device C0 to realize the machine tool. An interference check method by processing simulation before operation will be described.

I) Operation of CAD Program First, the designer starts up the CAD program PR1 stored in the work storage area F1 by the control device C1 and, for example, the three-dimensional data D1 of the work as shown in FIG.
Is designed (drawn) on the display L1 using the keyboard K1 or the mouse N1. At this time, the three-dimensional data D1 of the workpiece is the three-dimensional data D2 of the jig and tool.
And, like the three-dimensional data D3 of the cutting tool, the X axis, Y
It is composed of a set of coordinate data indicating each coordinate point on each coordinate axis in the Z-axis and Z-axis directions.
It is desirable that 2 and D3 be, for example, a set of solid type three-dimensional data including both coordinate data indicating coordinate points of those contour portions and coordinate data indicating coordinate points inside the contour portions. .

This is because the control device C1 will be described later.
The three-dimensional data D2 of the tool and the three-dimensional data D1 of the work supported by the tool and the three-dimensional data D3 of the cutting tool are displayed on the screen of the display L1, and the three-dimensional data D3 of the cutting tool is moved. When moving based on the trajectory data D4 and performing a machining simulation, the three-dimensional data D of the work or jig or tool.
This is because it is possible to easily determine whether or not there is an interference between the 1 and D2 and the three-dimensional data D3 of the cutting tool.

That is, the three-dimensional data D1 of the work, the three-dimensional data D2 of the jig and the tool, and the three-dimensional data D3 of the cutting tool.
If any two of them have the same coordinate data at the same time, interference occurs between them, whereas three-dimensional data D1 of the work, three-dimensional data D2 of the jig,
If any two of the three-dimensional data D3 of the cutting tool do not have the same coordinate data, mutual interference does not occur.

Therefore, in the control device C1, any two of the three-dimensional data D1 of the work, the three-dimensional data D2 of the jig and the three-dimensional data D3 of the cutting tool have the same coordinate data. It is possible to recognize whether or not interference occurs between the coordinate data of the three-dimensional data D1, D2, D3 by detecting the. However, the three-dimensional data D
1, D2, and D3 do not necessarily have to be made up of the solid-type three-dimensional data, and have, for example, only coordinate data indicating coordinate points of the contour portion, and coordinate data indicating coordinate points inside the contour. It may be made up of other data such as surface type three-dimensional data.

When the design (drawing) is completed, the display screen of the display L1 is set to, for example, a screen in which the upper, lower, left and right areas AR1 to AR4 are equally divided into four. Then, a plan view of the three-dimensional data D1 of the work as shown in FIG. 4 is displayed in the upper left area AR1, and the three-dimensional data of the work is displayed in the upper right area AR2. An isometric view of D1 is displayed, a front view of the three-dimensional data D1 of the work is displayed in the area AR3 at the lower left of the same, and a three-dimensional data D1 of the work is displayed in the area AR4 of the lower right of the same. A side view is displayed. And the three-dimensional data D of the work
1 is stored in the working storage area F4, and then the CA
The D program PR1 is terminated.

II) Operation of Tool / Tool Program Next, when the designer starts up the tool / tool program PR2 stored in the work storage area D2, an initial screen as shown in FIG. 5 is displayed. This initial screen is arranged at the upper and lower sides of the screen, and areas AR5 to AR8 in upper, lower, left and right, which are obtained by equally dividing the screen of the display L1 into four.
It includes a main menu bar (hereinafter simply referred to as a menu bar) M0, which will be described later, and a "command" column CM arranged at the lower end of the screen for displaying a predetermined message or the like.

A plan view of the three-dimensional data of the jig or the work is displayed in the area AR5 on the upper left side of the four-divided screen, and the area A on the upper right side is displayed.
In R6, an isometric view of 3D data of the same tool or work is displayed, and area A at the lower left of the same.
A front view of three-dimensional data of the same jig or work is displayed in R7, and the area AR8 at the lower right of the same is displayed.
Inside, a side view of three-dimensional data of the same jig or work is displayed.

On the menu bar M0, there are "application" M1, "data creation" M2, and "data deletion" M.

6, "Display" M7, "Drawing" M8, "Total" M9,
A menu "HELP" M10 is displayed side by side in the horizontal direction of the screen. Then, when a predetermined menu is selected from the menu bar M0 (the mouse N1 or the like is operated, the cursor displayed on the screen of the display L1 is placed on the predetermined menu and clicked), and the predetermined menu is selected. A pull-down menu is displayed below each menu.

Of course, the menu bar M0 does not necessarily have to be constructed as in the above embodiment, but may be arbitrarily increased or decreased according to need, and the arrangement of the menu bar M0 may be arranged. Need not necessarily be set in the illustrated embodiment, and may be arranged at any position on the screen.

In the area AR6 at the upper right, when the three-dimensional data D2 of the jig and the tool and the three-dimensional data D1 of the work are assembled, a total weight display list A indicating the total weight of these is displayed.
R9 is provided, and for the calculation method of total weight,
It will be described later. Note that the total weight display list AR9 does not necessarily have to be provided at this position, and normally, nothing is displayed, and it may be appropriately displayed when necessary.

Hereinafter, an example of a method of assembling the three-dimensional data D2 of the jig and the tool and the three-dimensional data D1 of the work will be described item by item.

(1) Selection / arrangement of processing machine The designer selects "selection / arrangement" from the menu bar M0.
When M4 is selected, as shown in FIG. 6, a menu called "machine data", "workpiece", "standard part", "special part", "machine data display", "dead area display", "interference check". Pull-down menu P4 consisting of
Is displayed below the "selection / arrangement" M4 on the menu bar M0 as a list in which the items are listed one above the other.

In this state, when the designer selects "machine data" from the pull-down menu P4 (by operating the mouse N1 or the like, placing the cursor on "machine data" and clicking), As shown in FIG. 7, the pull-down menu P4 is erased, and the data of the list showing the contents of the machine data (hereinafter referred to as the machine list K1) is displayed at the center of the screen of the display L1. , "OK" Z1, "Cancel" Y1 and "HEL" on the lower side of the machine list K1.
P ”H1 is displayed respectively.

The machine list K1 includes a plurality of registered symbols K2 and the like indicating usable machining machines (in the illustrated embodiment, the symbols "H-4" indicating four types of machining machines). “H-8”) Displayed in order of top and bottom. Then, from the symbol K2 indicating these processing machines, for example,
After selecting the symbol "H-4" K2 (by operating the mouse N1 or the like to place the cursor on the symbol "H-4" K2 and clicking), select the display "OK" Z1. (Operate the mouse N1 etc. to move the cursor to "OK" Z

The symbol K2 of "-4" is selected. As a result, when the symbol K2 indicating the processing machine to be used is selected, the data corresponding to the selected symbol K2 is stored in the storage area F4, and the machine list list K1 is displayed on the screen of the display L1. It is becoming more and more disappearing.

In the middle of this operation, when the selection of the symbol K2 indicating the processing machine to be used is stopped, the "cancel" is executed.
Y1 may be selected (the mouse N1 or the like is operated to position the cursor on "Cancel" and click). In addition, if an explanation about the processing machine is required during the operation, select "HELP" H1 (mouse N1
If the cursor is placed on the "HELP" H1 and clicked), the display L1
The screen has changed to display an explanation of the processing machine.

(2) Machine data registration method Next, when the designer selects "Create data" M2 from the menu bar M0, "machine data" and "dead area" are displayed as shown in FIG. , "Workpiece", "standard part", "special part", and "parametric" pull-down menu P2 is a list list in the order of top and bottom, and is below the "data creation" M2 of the menu bar M0. Is displayed.

In this state, the designer selects "machine data" from the pull-down menu P2 (by operating the mouse N1 or the like, placing the cursor on "machine data", and clicking), Since the machine data S0 including the loading range S1 and the tool stroke S2 is ready for input, by operating the mouse N1 or the like, as shown in FIG.
As shown in FIG. 3, machine data (three-dimensional data) S including a loading range S1 and a tool stroke S2 is displayed on the screen.
0 can be input and stored in the storage area F4. Incidentally, the size of the display L1 of the loading range S1 and the tool stroke S2 on the screen can be enlarged or reduced to an arbitrary size by a zoom function described later so as to make it easy to see. .

The loading range S1 indicates a range where the three-dimensional data of the work and the jig should be located, that is, a range which does not come into contact with the processing machine except the cutting tool portion when the processing machine is used. If the three-dimensional data of the work and the jig are arranged outside the range S1, the interference occurs with the processing machine. Further, the tool stroke S2 indicates the range reached by the tool when the machining machine operates. When the work is placed outside the tool stroke S2, the work cannot be machined. It will be.

(3) Assembling method of jig / tool a) Assembling of "base" Next, the designer selects "selection / arrangement" M4 from the menu bar M0 as described above, and further pulls down the selection. Select "Standard Parts" from the menu P4 as described above, then select "Base", "Stopper", and
"Supporter", "Clamper", "Adapter",
The "standard part name list" M4a in which the standard part names of "riser" and "accessory" are listed in the order of up and down is shown in FIG.
As shown in 0, it is displayed on the side of the pull-down menu P4 while overlapping on the display screen.

When the designer selects "base" from the "standard part name list" M4a (by operating the mouse N1 or the like, placing the cursor on the "base" and clicking), As shown in FIG. 11, the pull-down menu P4 and the "standard parts list" are deleted, and the "base selection" list B1 is displayed on the display screen.

In the list B1 for "base selection", data Ba of a tool ("base") consisting of an external view Bm of the tool ("base") and a part number Bn is stored in a plurality of the tool Ba. "Cancel" Y3 which is displayed so that it can be selected from the data and which is selected (the mouse N1 or the like is operated to place the cursor on "Cancel" Y3 and click operation) when the operation is canceled Is displayed below.

The designer confirms the external view Bm and the part number Bn of the "base" shown in FIG. 11, and confirms the data of a plurality of jigs ("base") displayed on the screen of the display L1. From Ba, select the data Ba of the desired jig ("base") (by operating the mouse N1 etc.,
The cursor is placed on a desired “base”, for example, the external view Bm of the “base” corresponding to the part number “BJ071” and clicked. Then, the data Ba of the selected desired jig (“base”) is displayed in the icon AW1 separated by another frame so as to overlap the list B1 for “base selection” (hereinafter, the list). Alternatively, for the item selected in the icon, the display portion H becomes black).

In this case, the external view Bm is enlargedly displayed in the icon AW1, the part number Bn is displayed in the left corner, and data BD1 showing various sizes is displayed.
And data BD2 indicating each type are displayed in a selectable manner. As a result, the designer selects one of the data BD1 showing various sizes (the mouse N1 or the like is operated to move the cursor to the data BD1 showing the desired size).
1. Place it on "400", for example, and click.)
In addition, one is selected from the data BD2 indicating the type (the mouse N1 or the like is operated to move the cursor to the data BD2 indicating the desired type, for example, “4025-12 (M
12) ”and can be clicked).

Then, the selection of the "base" data BD1 and BD2 of a desired size and type is completed, and the icon AW1 and the "base selection" list B1 displayed on the screen are displayed on the screen of the display L1. Disappear more.
Therefore, the previously displayed screen areas AR5 to AR
As shown in FIG. 9, the "state in which the loading range S1 and the tool stroke S2 are entered" is displayed on the screen 9, and the "command" column CM on the lower end side of the screen displays three-dimensional data of the selected base. A message (not shown) prompting the user to decide the location of the BA is displayed.

After that, the designer positions the placement position of the selected three-dimensional data BA of the base within the loading range S1 and the tool stroke S2 in any one of the four divided areas AR5 to AR8. When the mouse N1 or the like is operated as described above, the three-dimensional data BA of the selected base is, as shown in FIG.
The data is displayed at a predetermined position within the loading range S1 and the tool stroke S2, and is stored in the storage area F4 as assembled data D6.

Regarding the standard parts in the three-dimensional data D2 of the jig and tool, the data of the part name and the part number,
Since the unit weight data is stored together in the storage area F4, the control device C1 can recognize the unit weight data of the base three-dimensional data BA. Then, when the base three-dimensional data BA is stored in the storage area F4 as the data D6 in this way, the single weight data of the base three-dimensional data BA is displayed in the gross weight display list AR9.

(B) “Display of machine data” In this case, the three-dimensional data BA of the base, the loading range S1 and the tool stroke S2 are simultaneously displayed on the screen of the display L1 and are difficult to see, so the screen of the display L1 is displayed. As a result, the machine data S0 including the loading range S1 and the tool stroke S2 can be deleted (see FIG. 14).

As a concrete operation method, when "select / arrange" M4 is selected from the menu bar M0 and "machine data display" is selected from the pull-down menu P4 as described above, it is shown in FIG. "OFF" M42 and "O" on the side of the pull-down menu P4.
Both "N" and M43 are displayed. And the designer

In AR8, three-dimensional data RA1 of riser, three-dimensional data D1 of work, and three-dimensional data S of stopper
The mouse N1 or the like is operated so as to be at a predetermined position with respect to A1 and the three-dimensional data BA of the base.

Then, as shown in FIG. 39, the three-dimensional data CA2 of the selected "clamper" is divided into four areas of the upper, lower, left and right areas AR5 to AR8, and the three-dimensional data RA1 of the riser, A screen positioned with respect to the three-dimensional data SA1 of the stopper, the three-dimensional data TA1 of the special component (plate 4) and the three-dimensional data BA of the base is displayed and stored as the data D6 in the storage area F4.

A flow chart for realizing the height adjustment will be described with reference to FIG.

The controller C1 performs height adjustment according to this flowchart, but first determines whether or not to select a mode that allows height adjustment (step SE1).
Then, the designer places a cursor on the selection unit Sa3 and operates it to select a mode that enables height adjustment between predetermined positions (for example, h1) of the three-dimensional data D1 of the jig and tool.
Then, if YES is determined in step SE1,
In the "command" column CM at the lower end of the screen, the height between predetermined parts of the three-dimensional data of a plurality of jigs and tools is displayed so that it can be set or input as a dimensional value (step SE2). It is determined whether or not (step SE3).

When the designer places the cursor in the "command" column CM and operates it to select the height between the predetermined parts, the controller C1 determines YES in step SE3. , The following distance calculation is performed (step SE4). That is, for example, the distance between a specified surface displayed on the screen of the display L1 in the three-dimensional data D1, D2 of the work or jig and the coordinate point apart from this surface can be calculated mathematically. Calculation is performed using the calculation formula used for distance calculation.

Further, when the designer selects to input the height between the predetermined parts by the dimension value, the control device C1 judges NO in step SE3, and the designer makes a "command" at the lower end side of the screen. It waits for input of a dimension value (numerical value of length of distance) in the column CM (step SE5).

Then, the calculation is completed by using the calculation formula for calculating the distance, or the dimension value (the numerical value of the length of the distance)
41, the control device C1 retrieves the combination data (“BJ122-12001” “BJ510-12” from the combination data as shown in FIG. 41.
075 ″) is displayed (step SE6), and it is determined whether or not the combination data is selected (step SE6).
7). Here, from this combination data, the designer
("BJ122-12001""BJ510-120
75 ") is selected (YES in step SE7)
In this case, as described above, the control device C1 corresponds to the height (h1) between the predetermined positions or the height (h1) between the predetermined positions of the three-dimensional data of the jigs corresponding to the dimension value. h1)
Changes, and the appearance of the three-dimensional data of the jig corresponding to the setting of the height (h1) between the predetermined positions or the dimension value is displayed, for example, in the icon AW8 on the screen of the display L1 (step SE8). ).

In this case, the combined clamper (B
J122-12001 and BJ510-12075)
The desired height "range from 130.0 mm to 145.0 mm" can be dealt with. And
If the height (h1) between the predetermined positions or the dimension value is 140.0 mm, the shaft CJ of the clamper-BJ122-12001 is extended on the member BJ510-12075 by a predetermined length. Deploy.

Of course, the height between predetermined parts of the three-dimensional data of the jigs whose heights can be set as described above is set, or the height between predetermined parts of the three-dimensional data of a plurality of jigs is set or the dimension value is set. The configuration for displaying so that input can be performed does not necessarily have to be configured as in the above embodiment, and other configurations may be appropriately adopted. Further, since such a height adjusting function is a special function, it is not necessary if it is not necessary.

When the designer selects "edit" M5 from the menu bar M0 and further selects "copy" from the pull-down menu P5 shown in FIG. 42, the copy target can be designated. At the same time, a message (not shown) prompting the user to determine the copy object and its designated position is displayed in the "command" column CM at the lower end of the screen.

Then, the designer operates the mouse N1 or the like in one of the four divided areas AR5 to AR8 in the upper, lower, left, and right directions to specify the copy object (for example, the stopper three-dimensional data SA1). At the same time, a predetermined position to copy the designated copy object is designated. Then, the three-dimensional data SA1 of the stopper is positioned with respect to the three-dimensional data BA of the base, etc., and the four-divided areas AR5 to AR8 are shown in FIG.
As shown in FIG. 3, a screen for which the copying operation is completed is displayed for the copy target including the stopper three-dimensional data SA1 and the storage area F4 is stored as the data D6.
Is stored.

E) Interference check Next, the designer selects "select / select" from the menu bar M0.
Select "Arrangement" M4, and further select "Interference check" shown in FIG. 6 from the pull-down menu P4 (mouse N
Operate 1 etc. to place the cursor on the “interference check” and click.

Then, the three-dimensional data D1 of these works stored in the storage area F4 and the three-dimensional data D of the jig and tool are stored.
2, between the three-dimensional data D2 of the tool and the three-dimensional data D2 of the tool, between the three-dimensional data D2 of the tool and the machine data, and between the three-dimensional data D2 of the tool and the dead area. An interference check is performed on the screen of the display L1 to determine whether or not interference occurs with the three-dimensional data.
And, if any two of these three-dimensional data D1, D2, etc. have the same coordinate data at the same time, interference occurs between them, whereas any two of them occur. , If they do not have the same coordinate data, mutual interference does not occur. Therefore, the control device C1 detects whether or not there is interference, and if interference has occurred, the place where the interference has occurred is detected. For example, different colors are displayed on the screen. However, the occurrence of the interference may be notified or displayed by a sound, an error message, or other appropriate means.

As a result, the designer, for example, positions the three-dimensional data D1 of the workpiece, the three-dimensional data D2 of the jig and tool, the machine data and the three-dimensional data of the dead area so that the interference does not occur. Shift and redesign. However, this interference check does not necessarily have to be performed at this stage, and may be performed when the three-dimensional data D1 of the work and the three-dimensional data D2 of the jig and tool are assembled together.

W) Assembling of another accessory After the above-mentioned interference check, for example, another accessory may be assembled. That is,
As shown in FIG. 25, when the “accessory-selection” list Q1 is displayed on the display screen of the display L1, the designer selects a desired part number, for example, “BJ.
When the "accessory-" data Qa corresponding to "750" is selected, the selected desired part number "BJ750" is selected so as to overlap the "accessory-selection" list Q1 as shown in FIG. The data Qa to be displayed is displayed in the icon AW9 separated by another frame.

In this case, the external view Qm is enlargedly displayed in the icon AW9, the part number Qn is displayed in the left corner, and the data QD1 of various shaft diameters are displayed in a selectable manner. . As a result, the designer
By selecting one from the data QD1 of various shaft diameters, the selection of the "accessory-" data Qa of the desired shaft diameter is completed. Then, when positioning is performed in the above-described manner,
As shown in FIG. 45, a screen in which the accessory three-dimensional data CA3 is positioned with respect to the base three-dimensional data BA and the like is displayed.

By assembling the three-dimensional data of standard parts and special parts (three-dimensional data SA1, RA1, TA1, QA1 of stoppers, risers, special parts, accessories, etc.), the three-dimensional data D1 of the workpiece is corrected. It is surely supported by the three-dimensional data D2 of the tool. Then, it is necessary to terminate the jig / tool program PR2 and launch the CAM program PR3 to perform a machining simulation in a manner described later. In this case, CAM program PR3 and jig / tool program P
Since it is a different program from R2, it is necessary to store the three-dimensional data D1 of the workpiece and the three-dimensional data D2 of the jig and the like in which the interference has disappeared in the external recording medium.

However, in the above embodiment, the CAM
The program PR3 and the jig / tool program PR2 are different programs, but they do not necessarily have to be different programs. For example, one program supports the three-dimensional data D2 of the jig and the jig / tool. Assembling with the three-dimensional data D1 of the work, the three-dimensional data D3 of the cutting tool is displayed on the screen of the display L1, and the three-dimensional data D of the cutting tool is displayed.
3 is moved based on the movement trajectory data D4 to perform a machining simulation, and as a result of this machining simulation, the three-dimensional data D1 of the workpiece or the three-dimensional data D2 of the jig and the three-dimensional data D3 of the cutting tool are mutually interleaved. It may be possible to display on the screen of the display L1 whether or not there is interference.

F) Application registration operation Therefore, when the designer selects "application" M1 from the menu bar M0, as shown in FIG. 46, "application read", "application registration", and "application deletion" are performed. , "Application initialization" and "system termination" are displayed on the lower side of the "application" M1.

Then, the designer selects the pull-down menu P
When "Application registration" is selected from 1, the control device C1 outputs a signal instructing the registration operation to the input / output drive unit TD1, so that the input / output drive unit TD1 is stored in the external recording medium. , The data displayed on the screen of the display L1 is input and stored in an external recording medium. However, if the control device C1 can read the data and the like displayed on the screen of the display L1 from the memory ME when the jig / tool program PR2 is finished and the CAM program PR3 is started up, it is not necessarily external. It does not need to be stored in the recording medium.

(4) System end operation Further, when the designer selects "application" M1 from the menu bar M0 and further selects "system end" from the pull-down menu P1 shown in FIG. 46, control is performed. The device C1 ends the jig / tool program PR2.

III) Operation of CAM Program Then, when the CAM program PR3 is started up and the designer performs a predetermined operation, the control device C1 causes the memory ME to operate.
By reading out the three-dimensional data D6 of the work and the jig assembled from each other stored in the storage area F4 or by outputting a signal instructing the reading to the input / output drive unit TD1 The drive unit TD1 reads the three-dimensional data D6 of the workpiece and the jig assembled together, and as shown in FIG.
Display it on the screen of the display L1.

On the screen of this display L1,
In order to process the three-dimensional data of the workpiece among the three-dimensional data D6 (three-dimensional data SA1, RA1, TA1, QA1 etc. of the stopper, riser, special parts, and accessories) of the workpiece and jig that are assembled together. The cutting tool movement locus data D4 (see FIG. 48) for cutting the surface of the cutting tool, making a hole in the work, etc., is input and set using, for example, the mouse N1 and stored in the storage area F4.

After that, an automatic operation program for driving the NC machine tool, that is, an operation for creating an NC program is performed and stored in the storage area F4. This CAM program PR3 is as described above. Since a known "SmartCAM (registered trademark)" program is used, detailed description thereof will be omitted.

After the NC program D5 is created, the three-dimensional data D of the work and the jig assembled together are
6 is displayed on the screen of the display L1. afterwards,
The three-dimensional data D3 of the cutting tool is read from the memory ME, displayed on the screen of the display L1, and the three-dimensional data D3 of the cutting tool is based on the movement trajectory data D4 as shown in FIGS. 49 to 51. And move it to perform a machining simulation. As a result of this machining simulation, it is detected whether or not there is interference between the three-dimensional data of the work or jig and the three-dimensional data D3 of the cutting tool, and if there is interference, there is such interference. The spots are displayed on the display L1, for example, in different colors. However, the occurrence of the interference may be notified or displayed by a sound, an error message, or other appropriate means.

Then, the designer corrects the three-dimensional data D6 or the NC program so that the interference does not occur wherever there is interference, so that the NC program, which is a program for automatic operation, is changed. Once completed, it will be possible to perform automatic operation machining of machine tools.

Further, based on the corrected three-dimensional data D6, for example, when the machine tool is processing another work, by creating an output drawing, a statement of instruction, etc. relating to jig assembly, It is also possible to prepare the assembly of jigs and tools in advance outside the machine tool.

FIG. 63 shows a flowchart of the interference checking method by machining simulation of this embodiment. However, the method is not necessarily limited to this mode. As another mode, it is for machining simulation with NC program creating function. The following interference checks can be performed using the program.

That is, as shown in FIG. 64, the three-dimensional data D6 of the work and the jig assembled with each other is created (step SY0) and stored in the internal storage memory or the external storage medium of the computer. . On the other hand, by activating a machining simulation program with an NC program creation function, two-dimensional data or three-dimensional data of the work is input (read) from the internal storage memory or external storage medium of the computer device.
Yes (step SY1). Then, the three-dimensional data of the cutting tool is also input (read) from the internal storage memory or the external recording medium, and the movement locus data is input (step SY2), and then the NC program is created (step SY3). Then, the three-dimensional data of the workpieces and jigs assembled with each other created in step SY0 is input (read) from the internal storage memory or the external recording medium (step SY4), and the workpieces assembled with each other and The three-dimensional data of the jig and the tool and the three-dimensional data of the cutting tool are displayed on the screen of the display L1 (step SY5), the three-dimensional data of the cutting tool is moved based on the movement trajectory data, and the machining simulation is performed. Is executed (step SY6).

Then, whether or not there is interference is displayed on the screen of the display L1 (step SY7), and if there is interference (YES in step SY8), the three-dimensional data of the work and the jig assembled together, Or NC
The program is corrected and input (step SY9), and then steps SY4 to SY9 are repeated. Here, if there is no interference (NO in step SY8), the NC program is completed (step SY10), and automatic operation machining of the machine tool can be performed (step SY11).

However, in the case of the machining simulation shown in FIG. 64, when creating the NC program,
Since the three-dimensional data in which the work and the jig are assembled is not taken into consideration, it is highly likely that interference will occur when the machining simulation is executed, and steps SY4 to SY9 are likely to be repeated. On the other hand, in the case of the machining simulation shown in FIG. 63, when the NC program is created, the three-dimensional data of the work and the jig and tool assembled with each other are taken into consideration. The probability of occurrence of is less than that in the aspect shown in FIG. 64. Therefore, the mode shown in FIG. 63 has an advantage that the time required to complete the NC program is shorter than the mode shown in FIG. 64.

The program for creating the NC program and the program for performing the machining simulation may be different programs.

IV) Next, the flow chart of the jig / tool program PR2 will be described item by item based on FIGS. 52 to 59.
