- FIG. 2 is a block diagram showing an automatic programming device for implementing the tool path drawing method of FIG. 1, and Fig. 3 is a flow chart showing the operation of the programming equipment of Fig. 2.
- NC data is automatically created as conventionally known, and the created NC data is created.
- the data is executed.
- the work figure 1 representing the cylindrical work is drawn in a perspective view at the top of the display screen 25 in a three-dimensional manner.
- a two-dimensional YZ coordinate system is drawn in which the axis (Z axis) of the cylindrical work and the Y axis orthogonal thereto are coordinate axes.
- the tool trajectory 7 three-dimensionally represents the movement of the tool on the peripheral surface of the cylindrical work when performing processing on the peripheral surface of the cylindrical work in accordance with the actual processing condition. Since the tool movement position enters the back side of the work from the middle of the third section c to d of the tool path 7, the subsequent tool path 7 (hidden line) is drawn with a broken line. The end point a of the fifth section coincides with the start point a of the first section, thus clearly indicating that the tool goes around the workpiece surface. On the other hand, the tool trajectory 8 represents the movement of the tool on the YZ plane according to the machining drawing.
- the tool moves in the negative Y-axis direction in the first, third, and fifth sections a, b, c, c, d, e, and a, and the second section b
- ' ⁇ c' it is specified that it moves in the negative direction of the ⁇ axis at the same time that it moves in the negative direction of the Y axis
- the fourth section it moves in the negative direction of the ⁇ ⁇ ⁇ axis and in the positive direction of the ⁇ axis.
- the operator can easily confirm the movement of the tool by referring to both tool paths 7 and 8.
- the programming device automatically creates NC data based on a part program created interactively between the operator and the programming device and executes the NC data to draw a tool path. To do so.
- the programming device includes a processor (CPU) 21, and a read-only memory (R 0) is connected to the CPU 21 via a bus 29. M) 22, random access memory (RAM) 23, display control circuit 24, keyboard 26, disk controller 27, and interface Circuit 28 is connected.
- the display control circuit 24 is connected to a graphic display device 25 having a display screen 25a shown in FIG. 1 and comprising a brown tube or a liquid crystal display device.
- the controller 27 is equipped with a floppy disk 27a.
- the interface circuit 28 is connected to a printer, a tablet device, a plotter, and the like provided outside the programming device as necessary.
- the CPU 21 When the programming device is operated, the CPU 21 operates according to the control program read from the ROM 22, and the system program read from the floppy disk 27a, and The figure data file, tool file, machining condition file, etc. necessary for NC data creation are stored in RAM23.
- the operator operates the keyboard 26 to execute a series of operations written in an automatic programming language for machining the peripheral surface of a cylindrical workpiece (more generally, three-dimensional machining).
- a part program consisting of the part program statements of the above is created interactively with the programming device and input to the programming device.
- step S1 the CPU 21 determines whether or not the input part program sentence is a movement definition sentence (step S2).
- a figure definition or the like for a work shape or the like is performed prior to a motion definition, so that the determination result in step S2 is negative here. Therefore, the CPU 21 processes the input part program sentence, such as a graphic definition sentence, to generate NC data corresponding to the input part program sentence, and converts the created NC data to R data. Store it in AM 23 (step S7).
- the work shape data is sent from the CPU 21 to the display control circuit 24, and the work shape data is converted into the display signal by the display control circuit 2. Then, the work figure 1 is displayed on the display screen 25a of the display device 25 as shown in FIG. 1, and the YZ coordinate system in FIG. 1 is displayed.
- the CPU 21 determines whether or not the created NC data represents a program end, and determines whether or not the input of the part program has been completed (step S). 8) If the judgment result is negative, it waits for the input of the next part program sentence.
- step S2 If it is determined in step S2 that the part program sentence that is input thereafter is a movement definition statement that instructs the movement of the tool along the already defined figure in step S2, the input part program sentence is determined.
- Process the program sentence for the motion definition sentence create NC data corresponding to the input part program sentence, and store it in RAM 23. It is stored (step S3). If there is NC data that has been created by the previous processing cycle, the created NC data is converted into a display signal by the display control circuit 24 and is displayed by the display device 25 by the previous processing cycle.
- the tool path corresponding to the created NC data is drawn on the work figure 1 (Fig. 1) (step S4) For example, as shown in Fig. 1, the first section of the tool path 7 a to b are drawn, or a tool trajectory not shown in Fig. 1 for machining the work end face is drawn.
- the CPU 21 determines whether or not the NC data created in step S3 of the current processing cycle is related to the machining of the work cylindrical surface (step S5), and the NC data is, for example, a word. If the determination result in step S5 is negative, the process proceeds to step S8. On the other hand, if the NC data is related to the work cylindrical surface machining, and the determination result in step S5 is positive, the CPU 21 generates the NC data created in step S3.
- the tool path section for example, the second section b to c of the tool path 7 shown in FIG. 1 is calculated, and the tool path section is developed on the YZ plane. Calculate the sections b 'to c ,.
- the calculated data is supplied to the display device 25 via the display control circuit 24, and the tool trajectory sections b to c are drawn on the peripheral surface 2 of the work figure 1, as shown in FIG. At the same time, tool path intervals b, ⁇ c, are drawn on the YZ coordinate system (step S 6). Then, go to step S8.
- steps S1 to S8 are repeated, and, for example, as shown in FIG. 1, tool trajectories 7 and 8 are simultaneously drawn on the same screen 25a.
- the operator refers to the two tool paths 7, 8 corresponding to the input part program drawn on the display screen 25a while sequentially inputting the part program statements.
- the CPU 21 determines in step S8 that the input of the part program has been completed and draws the tool path shown in Fig. 3. The process ends.
- NC data (program) stored in the RAM 23 is transferred to and stored on the floppy disk 27a as necessary, and is also printed by the printer. It is printed out.
- the present invention is not limited to the above embodiment, and various modifications are possible.
- a program for processing a peripheral surface of a cylindrical work is created.
- the present invention can be applied to the creation of other three-dimensional processing programs.
