Problems solved by technology

However, for old-fashioned CNC punching machines such as C3000, only simple CNC coding programs are supported. The codes are mainly written step by step by technicians, and even a series of coordinate calculations are required before writing.
Not only the programming efficiency is low, but also the processing parts are prone to errors

Embodiment Construction

[0008] The present invention will be further described below in conjunction with the examples.

[0009] The steps of the method of the present invention are as follows: firstly, the present invention solidifies the processing environment and program of each working step of the components of the rolling stock product, and establishes it in a database for calling at any time. When processing parts, different subroutines are called to optimize the combination into a complete processing method.

[0010] According to the production batch and the structure of the parts, the part diagram is decomposed into several parts, and the subroutines are compiled for different parts. As shown in Schedule 1. According to the shape of the workpiece, the size of the processing, the thickness of the sheet, the material, the equipment of the tool and other related technologies. Use the same "0" point as the programming origin. Create a new program and offset the required subroutine to the machin...

Abstract

The invention relates to a processing method of a numerical control machine, in particular to a method of the numerical control machine utilizing a subprogram to realize the modularization processing. The method comprises the steps as follows: firstly, processing environment and program of each processing procedure are solidified and built in a database; when parts are processed, different subprograms are transferred to optimize and combine a complete processing procedure through the display of a menu, required graphs are moved to the appointed position through the deviation function, the required graphs are validated through the drawing function of programming software, thereby the quality of the object is ensured; according to the shape of a workpiece, the processing size, the thickness and the material of the panel, and the allocation information of the cutter, the same 0 point is adopted to be used as a programming origin, a new program is built, the required subprograms are deviated to the processing position and are verified through graph software, and a first workpiece is processed and goes into mass production after being mutually detected. The invention has simple programming, high precision, flexible operation and combination and allocation of modules, and can create products with different demands so as to meet the customized requirements of customers.

Description

technical field [0001] The invention relates to a processing method of a numerically controlled punching machine, in particular to a method for realizing modularized processing of a numerically controlled punching machine by using subprograms. Background technique [0002] With the rapid development of the machine industry, some performances of old-fashioned CNC equipment have fallen behind. Like the early CNC turret punch press without automatic programming software, it can only be programmed manually on the CNC system. The products of rolling stock are more complicated, such as the production of high-speed EMUs and the production of T-cars with a speed of 200 kilometers per hour. Having equipment and ability to improve product quality and efficiency is the primary issue. [0003] According to foreign statistics, when programming manually, the ratio of the programming time of a part to the actual processing time of the CNC machine tool is about 30:1, and 20% to 30% of the ...
