How about the development of CNC machining technology? ? ?

Generally speaking, the main content of Wuxi CNC machining process is as follows:

⑴ Select and confirm the parts and contents for CNC machining;

⑵ Process analysis of CNC machining of parts drawings;

⑶ Process design of CNC machining;

⑷ Mathematical processing of parts drawings;

⑸ Compile the processing procedure list;

⑹ Make the control medium according to the procedure list;

⑺ Check and modify the program;

⑻ First piece trial processing and on-site problem handling;

⑼The finalization and filing of CNC machining process documents.

In order to improve production automation, shorten programming time and reduce CNC machining costs, a series of advanced CNC machining technologies have been developed and used in the aerospace industry. Such as computer numerical control, which uses a small or microcomputer to replace the controller in the numerical control system, and uses software stored in the computer to perform calculation and control functions. This soft-connected computer numerical control system is gradually replacing the initial state of the numerical control system. Direct numerical control uses one computer to directly control multiple numerical control machine tools, which is very suitable for small batch and short cycle production of aircraft. The ideal control system is an adaptive control system that can continuously change processing parameters. Although the system itself is complex and expensive, it can improve processing efficiency and quality. In addition to the improvement of CNC systems and machine tools in terms of hardware, the development of CNC has another important aspect that is the development of software. Computer-aided programming (also called automatic programming) means that after a programmer writes a program in a numerical control language, it is input into the computer for translation, and the computer automatically outputs punched tape or tape. The most widely used CNC language is APT language. It is roughly divided into main processing program and post processing program. The former translates the program written by the programmer to calculate the tool path; the latter compiles the tool path into the part processing program of the CNC machine tool. Numerical control processing is to write programs on the computer before processing the workpiece, and then input these programs into the machine tool controlled by the computer program for command processing, or write instructions directly on the machine tool control panel controlled by the computer program For processing. The process of machining includes: cutting tool, changing tool, changing speed, changing direction, stopping, etc., which are all completed automatically. CNC machining is an advanced method of modern mold manufacturing and processing. Of course, CNC machining methods are not only used for mold parts processing, but also have a wide range of uses.
