Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention is applicable to work that involves machining a round hole by moving around the circumference using a laser processing machine or the like. The present invention relates to a method for calculating movement data for a numerical control device, which automatically calculates and corrects movement data for machining a round hole by selecting a diameter or the like.

[Conventional technology]

A conventional device of this type is shown in FIG. In the figure, person is a drawing for the workpiece, Bo is a machining condition data input unit for round hole machining (ST, 3), and D is an NC device and C is a movement data calculation unit for round hole machining (ST, 5).

and a movement data output section F (ST, 6) for round hole machining. And G is an NC laser processing device.

Next, the operation will be explained. In general, recent NC laser processing systems use the soft wired method, that is, N
CNC (computer NC), which can handle complex machining by simply changing the program while retaining the C functions, has become mainstream. However, even with such equipment, when creating a grogram for round hole machining, the laser movement data was created by simply inputting the machining dimensions, so data correction may be necessary depending on the hole diameter, etc. Although it was acknowledged, it was not taken into consideration.

That is, as shown in FIG. 5, for example, the dimension data value (ST, 3) input from the machining condition data input section BO for round hole machining is inputted to the movement data calculation section C0 for round hole machining.
In (ST, 5), it is converted into movement data suitable for a numerical control device for a processing machine and processed by a computer,
It is output as movement data F (ST, 6) for round hole machining. During the creation of the program, no corrections were made to the data due to processing material, plate thickness, hole diameter, etc. Therefore, the final result of the work is judged by the judgment section (ST, 7
), a message is output to the operator to ask him to make a decision as to whether or not to repeat the detailed machining, and the above operation is repeated according to the operator's selection.

[Problem to be solved by the invention] The conventional method of calculating movement data for numerical control is that when machining a round hole as mentioned above, if there is a servo characteristic as shown in Fig. 3, the round hole is When machining is performed, as the diameter of the machined hole becomes smaller, it moves inside the circle. In other words, the finished hole diameter will be smaller than the designated hole diameter. In such cases, it would be better to correct the dimensions each time after regular machining, but currently, the same dimensions are determined regardless of the hole diameter, so the machining accuracy decreases as the machined hole diameter becomes smaller. There was a problem with that.

This invention was made in order to solve the problems of the conventional method as described above, and it automatically specifies and corrects the optimum correction value commensurate with the hole diameter when machining a round hole using a laser.
The purpose of this study is to obtain a method for calculating movement data for a numerical control device that improves the accuracy of round hole machining.

[Means for solving problems]

Additionally, means is provided for calculating laser movement data using the optimum correction value.

[Effect]

The optimal correction value used in calculating the movement data for round hole machining in this invention has different values depending on the type of machining equipment, plate thickness, material, hole diameter, etc., but the above data must be input in advance. In particular, the optimum correction value is automatically selected and is used to automatically calculate the corrected movement data for round hole machining.

In addition, a reversal determining means (ST, 7) is provided so that round hole machining can be performed repeatedly under the same conditions.

In addition, in the above embodiment, an example related to round hole machining using an NC laser machining device was explained, but other two-dimensional round hole machining machines that move on the circumference and process round holes can be used with other machining machines.
