Abstract

PURPOSE:To shorten the producing time and to reduce the production cost of the numerical control data by setting the types, the positions and the sizes of plural different basic shapes as parameters for the contour line of a machining shape and at the same time connecting those parameters to each other with use of a symbol designating how to combine the basic shapes so as to automatically generate the numerical control data to a processing machine. CONSTITUTION:The input data are received through an input part 1, and a machining shape defined by the input data is regenerated at a machining shape production part 2. The part 2 regenerates the machining shape defined by the parameter and a symbol of the input data by reference to the basic shape registered into a basic shape register part 5. Then the numerical control data is automatically produced at a numerical control data production part 3 based on the regenerated machining shape. The obtained numerical control data are outputted to the outside through an output part 4.

Description

[Detailed description of the invention] [Industrial application field]

The present invention provides a method for creating numerical control data for contour machining, which creates numerical control data for a processing machine that processes along the contour of a desired machining shape.

[Conventional technology]

Traditionally, like wire electrical discharge machines and laser processing machines,
2. Description of the Related Art Processing machines have been provided that perform processing along the outline of a desired processed shape. Numerical control data for this type of processing machine is set by defining the position of the tool so as to trace the contour of the processing shape. That is, the numerical control data is expressed as a permutation of position data.

[Problem to be solved by the invention]

As described above, it is a very complicated task to express the locus of movement of the tool as a permutation of position data, and there is a problem in that it takes time and effort to create the numerical control data. In addition, in order to create numerical control data, it is necessary to learn a language specific to the processing machine, such as a numerical control language or a part program language, and training for the creator is costly.
There is a problem in that the cost required to create numerical control data increases. The present invention aims to solve the above problems, and it facilitates the creation of numerical control data required for contour machining.
The present invention aims to provide a method for creating numerical control data for contour machining that significantly reduces creation time and cost.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a method for creating numerical M# data for a processing machine that processes along the contour of a desired machining shape. Create an input code by combining the basic shapes, set the type, position, and dimensions of each basic shape as parameters, and combine the parameters using symbols that indicate how to combine the basic shapes. , the input code is translated to automatically generate numerical control data for the processing machine.

[Effect]

According to the above configuration, if the outline of the machining shape is defined as a combination of basic shapes, the numerical control data for the machining machine is automatically generated, so the creator of the numerical control data can convert the machining shape into the basic shape. All that is required is to disassemble the data and instruct the parameters and how to combine them, which greatly reduces the amount of work required compared to the conventional case of providing permutations of position data. Furthermore, since there is no need to learn a language specific to the processing machine, the cost required to create numerical control data is reduced.

【Example】

The process of creating numerical control data in the present invention is shown in FIG. 1. First, a desired machining shape is expressed as a combination of basic shapes registered in advance. A plurality of types of basic shapes, such as circles, rectangles, and triangles, are defined, and the desired processing shape is decomposed into a combination of these basic shapes. Next, let's look at the types of basic shapes that make up the machining shape. , set the dimensions as parameters. For example, if it is a rectangle, the type is REC1, the center position is X, Y, and the vertical and horizontal dimensions are H.
, V, etc., and REC, X, Y
, H, V. Figure 2 shows an example of defining the basic shape parameters. Figure 2 (a) shows a circle, Figure (b) shows a rectangle, Figure e) shows a rectangle with rounded vertices, and figure (d) shows an equilateral triangle.The types of basic shapes are CIR, REC, and RE, respectively.
C, TRf are shown, and the center position J, tX, Y is shown. Once the basic shape parameters are set, the combination method is instructed. The way the basic shapes are combined is expressed by an instruction symbol. For example, when selecting the outermost outline of a figure that overlaps basic shapes, use +, and when selecting the innermost outline, use 11. When selecting the outline of a common part of overlapping basic shapes, use ``book''. Figure 3 shows an example of the correspondence between the input code that combines parameters using these symbols, the state of superposition of the basic shape, and the machining shape defined by the input code. show. The machining shape is defined by the input code created as described above. Here, in order to confirm whether the input code corresponds to the desired machining shape, a contour line of the machining shape defined by the input code is automatically created. Here, if the input code does not correspond to the desired machining shape, the input code may be modified. Numerical control data is then automatically generated based on the contour of the machining shape defined by the input code, and then processed using paper tape or electrical Numerical control data is output in the form of signals. When a creator of numerical control data creates input data, it is sufficient to configure the device as shown in FIG. The machining shape defined by the data is reproduced by the machining shape creation section 2. The machining shape creation section 2 refers to the basic shapes registered in the basic shape registration section 5 and reproduces the machining shape defined by the parameters and symbols of the input data. If the desired processed shape is not obtained at this stage, the input data 1 is corrected. Then, based on the machining shape, the numerical control data creation section 3
Numerical control data is automatically created in the process. That is, a permutation of position data is generated corresponding to the machining shape reproduced by the machining shape creation section 2. The numerical control data obtained in this way is outputted to the outside through the output unit 4.The basic shape registered in the basic shape registration unit 5 described above can be changed by input from the input unit 1, and is necessary as the basic shape. This allows users to define shapes using a macro language. Using the above method, a processed shape A as shown in FIG. 5(a) is obtained.
For example, when processing the outline of
Create input data as shown in the following formula 8 ■ PT, Xi, Yl ■ +REC, X1. Y1. H, V, R■ -CrR,

The circled numbers in [Phase] correspond to the circled numbers in FIG. 5(b). When numerical control data is created using input data defined in this manner, a permutation of position data for moving the tool is automatically created as shown by the arrow in FIG. 5(e).

【Effect of the invention】

As described above, in the present invention, if the outline of the machining shape is defined as a combination of basic shapes, the numerical control data for the machining machine is automatically generated. The only work required is to decompose it into shapes and instruct the parameters and how to combine them, which has the advantage that the amount of work is significantly reduced compared to the conventional case of providing permutations of position data. In addition, since there is no need to learn a language specific to the processing machine, numerical fflNM
This has the effect of reducing the cost required to create data.
