Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a tooling determining device that can automatically determine the optimal tooling for a comb-shaped tool rest of a numerically controlled (hereinafter referred to as NC) lathe.

(Prior art) When multiple tools are mounted on the comb-shaped tool rest of an NC lathe, it is necessary to prevent the comb-shaped turret and tools not involved in machining from interfering with the workpiece or chuck during machining. . For this reason, in the past, operators themselves took into consideration the distance to adjacent tools, the shape of the workpiece, the shape of the jaws, the cutting location of the tool, etc., and placed the workpiece or chuck between the comb turret and tools not involved in machining. The optimal tooling that does not interfere with each other, that is, the foil-forming position and protrusion amount of the tools in the comb-shaped tool rest was determined.

(Problem to be Solved by the Invention) After determining the tooling for the comb-toothed tool post described above,
If there is a change in the mounting position or protrusion amount of a tool, it is necessary to recheck all tools to make sure they do not interfere with the workpiece, even if it is a single tool, which takes a lot of time. There were drawbacks. Furthermore, since the operator decides the tooling himself/herself, there is a problem in that calculation errors and oversights are likely to occur.

The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to enable the optimum tooling to be easily determined within a graphic display according to an operator's instructions.<1. (↓The purpose is to provide a tooling determination device for a type 1 tool post.

(Means for Solving the Problems) The present invention relates to a tooling determining device that can automatically determine the optimal tooling for a comb-shaped tool rest of an NC lathe. a generating means for generating a chucking diagram and a tooling diagram based on input data and registered data for determining tooling in the tool rest; displaying the chucking diagram and the tooling diagram from the generating means on a screen;
The method further comprises determining means for determining tooling in which the chucking diagram and the tooling diagram do not interfere with each other on the display screen in response to an external command, and displaying the determined tooling on the display screen and outputting the determined tooling to the outside. This is achieved by

(Function) The tooling determination device for the comb-tooth-shaped tool post of the present invention is configured so that the comb-tooth-shaped tool post, the tool, the workpiece, and the chuck are displayed graphically, and each display can be freely moved on the screen. This allows the operator to visually determine touring in a short time.

(Embodiment) FIG. 1 is a block diagram showing an example of a tooling determination device for a comb-shaped tool rest of the present invention. Necessary input data (workpiece shape, tool number used, jaw shape number, tool holder mounting position, etc.) 10 and registration data (tool holder shape, tool shape,
an input data storage section 4 and a registration data storage section 5 that respectively store the RD (nail shape, etc.) via the input control section 3; and input data 10 and 26m from the input data storage section 4, and registration data IO from the data storage section 5. A chucking diagram C11 showing the shape of the chuck and the shape of the workpiece held in the chuck, and a tooling drawing showing the shape of the comb-shaped tool rest and the shape of the tool attached to the comb-shaped tool rest. It has a shape generation section 6 that generates the figure TO.

Furthermore, the chucking diagram CI+ and the tooling diagram 'rU from the shape generating section 6 are displayed on the display device l, and the tool is placed at a mounting position 1θ that does not interfere with the workpiece according to the operator's command SS input from the pulse handle 8 or 1-shaping section 2. is determined, and the determined tool mounting position data PI) is added to the tooling diagram Tll and displayed on the display device 1,
The tooling determining section 7 outputs the determined tool mounting position data PD to a printer or floppy disk 10 via a data output section 9.

In such a configuration, an example of the operation of the touring determining section 7, which is the main part thereof, will be explained with reference to the flowchart of FIG. For example, the display device 1 displays a chucking diagram C11 and a tooling diagram TIJ as shown in FIG. When processing the inner circumferential surface of the workpiece W, the operator operates the pulse handle 8 or the operating section 2 to move the tooling diagram Tll and position the tip of the tool A on the end surface of the workpiece W (step St). Then, the tooling diagram Tll is moved within the machining range of tool A (within the arrow ^1 shown in the figure), and the workpiece W, chuck CK, and tool 0. It is confirmed whether or not there is interference between C and the comb-shaped tool rest TS (step S2). In this case, since the workpiece W and chuck C do not interfere with the tools n and C and the comb-shaped tool rest TS, it is further confirmed whether there are any tools for which the interference check has not been completed (step S4).

In this case, since tool B is present, the tip of tool B is positioned on the outer circumferential surface of workpiece W as shown in FIG. ), the tooling diagram TO is moved, and it is confirmed whether or not the workpiece W and the chuck L interfere with the tool, C and the comb-shaped tool rest TS (step S2).

In this case as well, since there is no interference between the workpiece W and the chuck C and the tool, and between C and the comb-shaped tool rest TS, the interference check is further completed and the presence or absence of the missing tool is checked (step 54).

In this case, since the tool C is present, the tip of the tool C is positioned at the inner periphery of the workpiece W as shown in FIG. 5 by the same operation as described above (step Sl). At this time, move the chucking diagram CI+ to the top of the screen to display the tooling diagram TU.
so that it does not protrude from the screen. Then, draw the tooling diagram TO in the machining range of tool C (inside the arrow Ae shown in the figure)!
It is confirmed whether or not the workpiece W and chuck CK interfere with the tools a, C and the tooth-shaped tool rest TS (step S2). In this case, the workpiece W and the tool B interfere (shaded area IV in the figure), so the workpiece
1. Let B work until M does not interfere with work W (
Step S3). Note that if only the rear part B is moved, there is a possibility that tool A and workpiece W will interfere when machining with tool B, so at the same time as tool B is moved, tool A is also moved by the same distance in the direction of tool B's movement. move automatically.

Then, it is checked whether there are any tools for which the interference check has not been completed (step S4). If there are no tools for which the interference check has not been completed, each of the determined tools A is checked.

Step S5: Add the mounting position data PD of 8.6 to the tooling diagram Tυ and display it on the display device l (Fig. 7), and output the determined mounting position data IID of each tool A, B, and C to the outside. ), all processing ends.

(Effects of the Invention) As described above, according to the tooling determination device for a comb-tooth type tool rest of the present invention, the operator can simply input commands while looking at the graphic display, making it possible to quickly and accurately determine the optimal tooling. In addition, it is possible to significantly reduce the number of man-hours.
