Numerical control machining technology mainly includes the content

Numerical control processing, is generally refers to the numerical control machine tools on the parts processing process. Numerical control machine tool is a computer to control the machine tool, used to control the machine tool computer, whether it is a special computer, or general computer are collectively called numerical control system. The movement and auxiliary action of CNC machine tools are controlled by the command issued by the CNC system. The instructions of the numerical control system are compiled by the programmer according to the material of the workpiece, processing requirements, the characteristics of the machine tool and the instruction format specified by the system (numerical control language or symbol).

It is the key to realize NC machining programming. But light programming is not good, CNC processing also includes programming must be done before a series of preparatory work and programming after processing work. Generally speaking, CNC machining process mainly includes the following contents:

(1) mathematical processing of parts drawings;

(2) Preparation of processing program list;

(3) according to the program to make the control medium;

(7) verification and modification of the program;

(4) Trial processing of the first piece and on-site problem handling;

(5) Finalize and file the NC machining process documents.

(6) Select and determine the parts and contents of CNC machining;

(7) NC machining process analysis of parts drawings;

(8) numerical control machining process design;

Numerical control machining programming methods have manual (manual) programming and automatic programming points. Manual programming, the entire content of the program is written manually according to the instruction format specified by the numerical control system. Automatic programming is computer programming, which can be divided into automatic programming methods based on language and painting. However, no matter what kind of automatic programming method is adopted, it is necessary to have corresponding supporting hardware and software.
