This invention relates to a machining shape definition method when automatically creating a machining shape.

(Prior art) The machining shape definition method in the conventional interactive automatic programming function divides the shape surrounding the tool path or the area to be machined into multiple straight lines or circular arcs, and then selects the corresponding shape from among these straight lines or circular arcs. This is done by selecting the shape and specifying its shape data. However, in some cases, shapes that are not directly related to machining may be defined as auxiliary shapes,
There is a machining shape definition method in which the machining shape cannot be defined unless a shape that matches the machining shape is reused as an auxiliary figure.

In such a configuration, the operation will be explained using the flowchart shown in FIG. If it is determined that the data does not require an auxiliary figure, the processed shape data is input (step S2), and all processing is completed. On the other hand, in the judgment step Sl, if the operator etc. judges that the machining shape data requires an auxiliary figure, the operator etc. searches for a shape that is likely to become an auxiliary figure from the machining drawing and names it. is added and its auxiliary figure data is input (steps S3 and S4
). Further, the operator or the like checks the processing drawing to see if there is a shape that could be an auxiliary figure based on his or her own judgment (step S5), and if it is determined that there is a shape that could be an auxiliary figure, the operator or the like checks the processing drawing in step S3. Return to and repeat the above operation. On the other hand, in the judgment step S5,

Then, the operator etc. confirms whether or not the machining shape has been defined (step S7). If it is determined that the machining shape cannot be defined, the operator returns to step S3 and repeats the above-mentioned operation. Further, if it is determined that the machining shape has been defined, all processing ends.

(Problems to be Solved by the Invention) In the method of defining the machining shape described above, the operator etc. searches for shapes that are likely to be auxiliary figures from the machining drawings based on his or her own judgment. It has been difficult to judge in advance whether the machining shape can be defined. Then, the machining shape may not be defined by the auxiliary graphics determined by the operator or the like, or a different machining shape may be defined.

The present invention was made in view of the above-mentioned circumstances, and an object of the present invention is to provide an interactive automatic programming function that allows the definition of machining shapes by defining auxiliary figures without relying on the judgment of an operator or the like. The object of the present invention is to provide a processing shape definition method.

(Means for Solving Problems) The present invention relates to a machining shape definition method in an interactive automatic programming function that automatically creates an NG program for controlling an NG machine tool. If an auxiliary figure is required to obtain machining shape data for defining the machining shape, select a pattern corresponding to the auxiliary figure from the menu shown, input the data of the auxiliary figure, and then This is achieved by defining an auxiliary figure, obtaining the machining shape data, and defining the machining shape using this machining shape data.

(Function) The machining shape definition method in the interactive automatic programming function of the present invention defines the machining shape by selecting a corresponding pattern from among the pre-stored auxiliary graphic patterns, making it easy to define the machining shape. and can be precisely defined.

(Example) FIG. 1 is a block diagram showing an example of a device having an interactive automatic programming function that realizes the machining shape definition method of the present invention, corresponding to FIG. The explanation will be omitted. This device having an interactive automatic programming function outputs a command Sl to the screen display unit 13 to display a menu consisting of a plurality of auxiliary figure patterns instead of the input auxiliary figure storage unit 3, and
An auxiliary figure shape calculation unit 11 that calculates processing shape data SJ based on the auxiliary figure data S[+ from the key data input unit 2, and an auxiliary figure shape calculation unit 11 that calculates processing shape data SJ based on the auxiliary figure data S[+ from the key data input unit 2, and an auxiliary figure shape calculation unit 11 that calculates processing shape data SJ based on the auxiliary figure data S[+], and an auxiliary figure shape calculation unit 11 that calculates processing shape data SJ based on the auxiliary figure data S[+ Menu storage area 1
2, and a screen display section 13 that reads the menu S from the auxiliary graphic menu storage area 12 and displays it on the CRTIO in accordance with the menu display command Sl from the auxiliary graphic shape calculation section 11. Furthermore, the conventional machining trajectory calculation unit 4
Instead, a machining trajectory calculation section 14 is provided that calculates machining trajectory data SF based on the machining shape data SC from the key data input section 2 and the machining shape data SJ from the auxiliary figure shape calculation section 11.

In such a configuration, the operation will be explained with reference to the flowchart shown in FIG. If it is determined that the data does not require an auxiliary figure, the machining shape data is input (step 512), and the process proceeds to step 51B. On the other hand, in the judgment step Sll, if the operator etc. judges that the machining shape data for defining the machining shape requires an auxiliary figure, Cr1T10
Select a pattern corresponding to the auxiliary figure from the menu displayed in step 513), and define the auxiliary figure in an interactive manner. After that, the operator etc. decides whether or not further auxiliary figures are required to define the auxiliary figures (step 514). If it is determined that further auxiliary figures are necessary, from the menu displayed on CnT10, Select a pattern corresponding to the auxiliary figure and define the auxiliary figure interactively (step 515), step 517
Proceed to. On the other hand, in the judgment step 514, if the operator or the like determines that the auxiliary figure is not necessary for defining the auxiliary figure, the auxiliary figure data is input (
step 516). Then, in step 517), the operator etc. confirms whether or not the input of sufficient auxiliary figure data to obtain machining shape data or further auxiliary figure data is sufficient to obtain machining shape data. If it is determined that data input has not been completed, the process returns to step 514 and the above-described operations are repeated. On the other hand, if the operator or the like determines in the judgment step 517 that the input of auxiliary figure data sufficient to obtain the machining shape data is completed, or if the machining shape data has been input (step 512), the machining Check whether input of machining shape data for defining the shape has been completed (step 518), and if it is determined that input of machining shape data for defining the machining shape has not been completed, step Sll The process returns to and repeats the above-described operations, and if it is determined that the input of machining shape data for defining the machining shape has been completed, the machining shape is defined and all processing ends.

Next, a case will be described in which a processed shape of a circle C1 centered at the intersection 0 of the diagonals Ill and u2 of the rectangle shown in FIG. 3 is fixed. First, in step 511), the operator or the like determines whether an auxiliary figure is necessary to find the center point O, which is the machining shape data of the circle C1. In this case, all that is known is that the center point O is the intersection of the diagonal lines l and Il,2, so the operator, etc., decides that an auxiliary figure is necessary and does not display it on the CRTIO, for example, the fourth
From the menu shown in the figure, select the pattern "1. Intersection point of two straight lines °" that can define the intersection of two straight lines (step 513). Then, the operator etc. select the diagonal line I1.
．． It is determined whether additional auxiliary figures are required to define 1 (step 514). In this case, the diagonal I1.
Since it is clear that l passes through two points Pi and P2, the operator determines that an auxiliary figure is not necessary and inputs the shape data of the diagonal line Ql in an interactive manner (step 516). Then, check whether the operator etc. has finished inputting sufficient auxiliary figure data to find the center point O (step 517); in this case, the diagonal ρ2 is still
remains, so repeat the above operation in step 51.
4 to 517), find the center point O. Then, the operator etc. confirms whether or not input of machining shape data for defining circle C1 has been completed (step 518). In this case, since the radius of circle CI still remains, the radius is calculated from the diameter of circle C1. (step 512) to define the circle CI.

(Effects of the Invention) As described above, according to the machining shape definition method in the interactive automatic programming function of the present invention, it is possible to easily define auxiliary figures and machining shapes from pre-stored auxiliary figure patterns. By doing so, it is possible to prevent errors in judgment by operators and the like, and to significantly reduce the number of man-hours required when creating an NG program.
