JPS62217309A - Working method by cad/cam - Google Patents

Abstract

PURPOSE:To improve the machine working efficiency by deciding and storing previously the machine control and working conditions. CONSTITUTION:All data on the machine control and working conditions needed for machining and working of various working materials are registered to an NC device set at the machine side in the form o a program. At the same time, the material code name is registered at the CAD/CAM side together with the name of the program registered to the NC device at the machine side. In a working mode, the CAD is used to design a working form and the code of the working material is finally supplied. Thus the subprogram call instructions for working material are put automatically before and after the working form. Thus an NC tape containing the machine control data and the working conditions is produced to carry out smooth execution of various machining and working operations.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application: The present invention improves the applicability of processing conditions and machine control of a processing machine, thereby enabling processing under optimal conditions at all times.
This relates to a processing method using CAD/CAM that enables the creation of C tape.

Background of the Invention: In most cases, processing using various types of tools such as laser processing machines, lathes, wire cuts, machining centers, electrical discharge machines, and water jets is performed using machines equipped with NC devices. In other words, CAD,! : Designing the processed shape by computer-aided design (hereinafter simply referred to as CAD) called CAM, and then manufacturing by computer-aided manufacturing (hereinafter simply referred to as CAM).
VC, and in this CAM, based on the machining shape data created with CAD, an NC tape is created with data that defines machine control and machining conditions, and machining is performed accordingly.

If CAD and CAfvI are not related under certain conditions, the machining shape data (movement of the machining table, etc.) by CAD is transferred to the NC device attached to the machine, and the machine control data (7Jll Parts other than table movement, such as opening and closing the shutter of the oscillator in a laser processing machine, releasing assist gas, etc. )or,
Processing condition data (for example, in the case of a laser processing machine, cutting speed, output, assist gas settings, etc.) is manually generated using NC language.

In this case, machine control and machining condition data are basically entered before and after data of one machining shape. and,
When machine control and machining conditions often require the same data, these data are registered as a subprogram and placed in -C, and subprogram call commands are manually issued before and after the machining shape data.

Prior art #: A method that integrates CAD and CAM as described above and creates data for the organically related metal C1 machining shape directly controlling the machine control and machining conditions has attracted attention, and has been developed in a concrete manner. The one proposed is Roru.

This is an integration of CAI) and CAM using a suitable interface.

The machining shape data obtained with CAD is transferred to CAM via communication, and the machine control and machining conditions are controlled by the NC device attached to the machine.
The so-called Behind the Tape Read allows you to receive information as if you were reading an NC tape.
There is an r-style DNC. With this method, once you master the manual method of processing shapes, you can immediately perform appropriate processing. However, C.A.
The function of M is dominant and integrates CAD and CAM;/j
It was difficult to say CAD/CAM.

In some cases, the computer and the processing machine are connected via serial transmission. It is a DNC combination of a machining shape design section equivalent to CAD and a machine control and labor information creation section such as CAM conditions equivalent to CAM, but it lacks analysis functions and takes a long processing time. This was a difficult point.

Problem to be solved by the invention: The present invention is designed to solve all of the above-mentioned problems.It converts one work and processing means into data using a machine, and always stores it as a subprogram.2@When necessary. The objective is to provide a method for efficiently performing machine work and machining by automatically invoking a subprogram call command that satisfies adaptability.

Structure and operation of the invention: The CAD/CAM processing method of the invention will be explained below.

All data related to machine control and processing conditions necessary for machining and processing of various processing materials are stored in advance on the machine side.
Register it in the C device as a subprogram.

At the same time, the material code name for displaying the processed material and the subprogram name registered in the NC device of the machine are registered in CAI/CAM.

When actually machining the machining material, use CAD to design the required machining shape, and then input the material code of the machining material at the end. Subprogram call instructions for that machining material will be automatically executed before and after one machining shape. As long as the machine control data and machining conditions are entered into the NC tape, the following various machining operations and machining operations can proceed smoothly.

Specific example: CAI)/CAM only automatically inputs subprogram call instructions, so there is no need to handle machine control data and machining condition data. Therefore, in the CAD/CAM processing method of the present invention, any type of machine can be used as long as the handling of the figure processing data of the NC device attached to the machine is the same, that is, as long as the so-called G code is the same. It is also applicable to Also G
Even when the code is different, changes are extremely easy and can be followed immediately, which improves the versatility and contributes to the usefulness of the method of the present invention.

Effects of the invention: In the CAD/CAM method of the present invention,
Since machine control and processing conditions are formulated and stored in advance, a data bank that can be used effectively by the user is inevitably created.

Since the processing conditions are originally determined by the use of the machine, it is preferable that the part that creates the data bank for this purpose be the NC device closest to the machine.

Furthermore, if the nfC is found to have better working conditions than the one currently in use, it is sufficient to change the entire contents of the subprogram. N produced using the method of the present invention
C tape can always be processed under optimal conditions.

As described above, the CAD/CAM-based Caloe method of the present invention can be performed using a laser processing machine, a lathe, a wire cut,
In addition to demonstrating excellent machining efficiency when applied to machining centers, electric discharge machines, water jets, etc., it is also possible to create a machining condition data bank that is useful to the user, and furthermore, by utilizing this data bank, It has a cumulative effect on the efficiency of machining and processing of processed materials, and has great industrial applicability.
