CAM system for automobile longeron punching processing and control method and construction method thereof

Abstract

The invention relates to a CAM system for automobile longeron punching processing, which is characterized by comprising a device for reading a CAD file, a device for establishing a link, an icon menu and an interface for a CAD / CAM system, a device for transforming the data in the CAD file into data with the mould model and size data of the CAM system, a device for mould adaptation and optimization and simulation running, a device for generating an NC data program from the data, a device for transmitting the NC data program to punching numerical control equipment and numerical control punching equipment. A control method of the CAM system for automobile longeron punching processing is characterized by comprising the following steps of: reading the CAD file; establishing the link, the icon menu and the interface for the CAD / CAM system; transforming the data in the CAD file into data with the mould model and size data of the CAM system; carrying out mould adaptation and optimization and simulation running; generating the NC data program from the data; transmitting the NC data program to the punching numerical control equipment; and carrying out processing operation by the numerical control punching equipment.

Description

technical field [0001] The invention relates to the technical fields of a control system for a numerically controlled punching production line and computer-aided manufacturing (CAM), in particular to a CAM system for a longitudinal beam of an automobile remodeled and trial-manufactured, a control method, and a system construction method. Background technique [0002] At present, the integrated CAD / CAM software with numerical control programming function used for stamping equipment in the world mainly includes PROCAM software of TEKSOFT Company of the United States, NEWCAM of Taiwan Shixin Technology, AP100 of Japan Amada Company and other CAM automatic programming software. These software are integrated CNC machining function module. However, for the special CNC punching production line for automobile longitudinal beams, because there is no CNC machining functional module system supported by CAD / CAM integrated software, it cannot meet the requirements of this special punchin...

AI Technical Summary

Problems solved by technology

[0003] The above various programming control methods have low efficiency, high error rate, many steps, and cumbersome, once the graphics are changed, they have to start all over again.

There are the following three types of disadvantages: (1) programmers need to learn and master the CNC language, (2) need to convert the information of the processed parts into text or digital information, which is not only not intuitive, but also has a high error rate during the conversion process, (3) NC language programming still adopts batch processing at present, that is, the part source program written in NC language is only processed once after being input into the computer, and manual intervention cannot be performed during the processing, so that the operation result of the instruction code cannot be modified. Vehicle stringers for remodeled and pre-production models require frequent revisions

[0004] Due to the limitations of the above-mentioned control software, the control of the punching CAM system is backward, and the technical performance, versatility and efficiency are relatively poor
