Abstract

PURPOSE:To facilitate the correction of a definition shape by designating an area that is replaced with an added shape element. CONSTITUTION:A definition shape SL for numerical control which is defined via a keyboard 1 and a shape data input part 2 is stored in a definition shape storing part 3. When the additional shape element data SE is inputted via the keyboard 1, an additional shape element data input part 6 calculates a definition shape element SG and supplies it to a definition shape correction part 8. At the same time, a definition shape SK is read out of the part 3. A correcting shape designation part 7 designates a desired shape element to be corrected in response to a command SF received from the keyboard 1 and then designates an area to be replaced with the element SG to supply a designated shape element SI and a designated area SH to the part 8. The part 8 replaces a designated area SH of the element SI of the element SL of the part 3 with the element SG and stores a corrected designation shape SJ in the part 3. Thus a definition shape is easily corrected with a simple operation.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention modifies a shape defined in a numerical control (NC) program or a function for creating NC information such as a command to operate a numerically controlled machine. Concerning husband.

(Prior Art) FIG. 4 is a block diagram showing an example of a device having a general NG information creation machine fi, in which shape data SA is manually input to the shape data human input section 2 via the keyboard 1, and the shape A defined shape 5B based on the data S^ is calculated and stored in the defined shape storage section 3. Then, the machining path generation shape data SC is read out from the defined shape storage section 3 to the machining path generation section 4, and the machining path data S is used to create NC information.
D is generated and stored in the machining path data storage section 5.

Here, the defined shape correction method in the conventional NC information creation function will be explained with reference to the flowchart in FIG. If there are no unnecessary shape elements in the defined shape, the process advances to step S3, and if there are unnecessary shape elements in the defined shape, all unnecessary shape elements are deleted (step S2). Roughly speaking, the operator determines whether or not there is a shape element that requires modification in the defined shape.Step 53) If there is no shape element that requires modification in the defined shape, the process proceeds to step S5; If there are shape elements that need to be changed in the defined shape, all the shape elements that need to be changed are changed (step 54).

Then, in step S5, the operator determines whether or not there is a shape element that requires an additional shape element in the defined shape.
), if there is no shape element that requires an additional shape element in the defined shape, all processing ends, and if there is a shape element that requires an additional shape element in the defined shape, add the additional shape element All the steps are added (step S6), and all processing ends.

(Problems to be Solved by the Invention) For example, line segment 9.10 shown in FIG. 6(a),
11, 12. When modifying the defined shape composed of 13 as shown in the same figure (C), the end point p1 of the line segment 11, which is the shape element that requires modification, is changed as shown in the same figure (b). The point p2 is changed to the line segment 11a, and the grooved shape 11b, which is an additional shape element shown in FIG. It is necessary to add a line segment 11c connecting p3 and point +1+ as an additional shape element. In this way, in the conventional defined shape correction method in the NC information creation function, the line segment 11c is added to the additional shape even though the line segment 11c is a part of the line segment 11, which is a shape element of the initially defined shape. Since it has to be added as an element, there is a drawback that the operation for the operator becomes complicated.

The present invention was made in view of the above-mentioned circumstances, and an object of the present invention is to provide a method by which a defined shape in an NC information creation function can be easily modified.

(Means for Solving the Problems) The present invention relates to a method of modifying a shape defined in an NC information creation function, and the above object of the present invention is to
specifying a shape element that requires modification in the defined shape;
This is achieved by specifying a region in the designated shape element that will replace the added shape element, and replacing this designated region with the additional shape element.

(Function) With the definition shape modification unit 7 in the NC information creation function of the present invention, only the designated part of the designated shape element is replaced with the additional shape element, and parts other than the designated part can be used as they are, so the operator operation can be simplified.

(Embodiment) FIG. 1 is a block diagram showing an example of a device for implementing the defined shape modification method in the NC information creation function of the present invention, corresponding to FIG. The explanation will be omitted. The additional shape element data SE is manually entered into the additional shape element data input section 6 via the keyboard 1, and the defined shape element SG based on this additional shape element data SE is calculated and sent to the defined shape modification section 8. On the other hand, the defined shape SK stored in the defined shape storage section 3 is read out to the modified shape specifying section 7, the shape element that needs to be modified is specified according to the command SF input from the keyboard, and is replaced with the defined shape element SG. The region in the designated shape element is designated and sent to the defined shape modification unit 8 as the designated shape element sr and designated region SN. Then, the defined shape SL stored in the defined shape storage section 3 is read out to the defined shape correction section 8, and the designated shape element Sr in this defined shape SL is read out.
The designated portion SN of is replaced with the defined shape element SG, and is stored in the defined shape storage unit 3 as the modified defined shape SJ.

In such a configuration, an example of its operation will be explained with reference to the flowchart in FIG. 2. The operator specifies the shape element that needs to be modified, and specifies the part of the designated shape element that will be replaced with the additional shape element (steps S7 and S8). ). This specification method includes, for example, manually inputting the coordinate values directly from a keyboard, or displaying them graphically and manually inputting them using a light pen. Then, the specified portion is replaced with an additional shape element (step S9), and all processing is ended.

For example, the line segment 14 shown in FIG.
, 15, 1 [i, 17, and 18, as shown in Figure (c), specify line segment 16, which is the shape element to be modified, and modify the defined shape as shown in Figure (b). As shown, the part to be replaced with the threaded shape 16b, which is an additional shape element,
That is, specify the area between point p4 and point s. And the same figure (c)
As shown in the figure, the designated area between point p4 and point 95 is threaded into the threaded shape 16b M? exchange. As a result, the line segment 16 is divided into three shape elements: a line segment 16a, a threaded shape +6b, and a line segment 11ic.

In addition to the threaded shape described above, the additional shape elements that can be replaced include a grooved shape and a holed shape.

(Effects of the Invention) As described above, the ability to correct defined shapes in the NC information creation mechanism of the present invention? According to the above, the defined shape can be easily modified, which reduces the burden on the operator and greatly improves work efficiency.
