What is Cnc machining definition：
Traditional Cnc machining and manufacturing is manual operation of ordinary machine tools, the processing of the machine tool cutting metal, the eye with calipers and other tools to measure the precision of the product.Modern industrial homework already using computer digital control machine tool, CNC machine tools can be programmed in advance in accordance with the technical personnel program automatically to any directly processed products and parts.This is what we call numerical control processing.Cnc machining industry is widely used in any field of mechanical processing, and it is also an important and necessary technical means for mould processing.
"CNC" is the abbreviation of "Numerical Control" in English.
Nc machine tool is prepared according to the pre-programmed processing procedure, automatic processing of the processed parts.We put the parts of the processing craft route, process parameters and tool trajectory, displacement, cutting parameters and auxiliary functions, in accordance with the instruction code and procedures prescribed by the CNC machine format write into the processing program list, then this program list the contents of the records in the control medium, and then input to the numerical control machine tool numerical control device, thereby command machine parts.
Cnc machining equipment is to use digital information to mechanical motion and working process control technology, numerical control equipment is new technology represented by numerical control technology to the traditional manufacturing industry and emerging manufacturing the penetration formation of the electromechanical integration products, the so-called digital equipment, such as CNC machine tools, etc.Its technology involves many fields :(1) Cnc machining technology;(2) information processing, processing and transmission technology;(3) automatic control technology;(4) servo drive technology;(5) sensor technology;(6) software technology, etc.
Numerical control technology and equipment are the enabling technologies and the most basic equipment for the development of new high-tech industries and sophisticated industries.The information industry, biological industry, aviation, aerospace and other defense industries of the world have adopted the numerical control technology extensively to improve the manufacturing capacity and level, and improve the adaptability and competitiveness of the market.The development of advanced manufacturing technology based on numerical control technology has become an important way for developed countries to accelerate economic development and improve overall national strength and national status.
High speed development
With the improvement of the performance of the core processor of the numerical control system, the speed of the current high-speed machining center can reach up to 80m/min and the air speed can reach about 100m/min.
With the progress of servo control technology and sensor technology, the machine tool can perform accurate motion of submicron level under the control of nc system.
Due to the standardization and modularization of computer hardware and the modularization of software, the open technology is becoming more and more mature, and the numerical control technology is entering the open stage.Open CNC system has better versatility, flexibility, adaptability and expansibility.
With the complexity of the product appearance curve, the mould processing technology must be constantly upgraded, and the new demand for the CNC system is put forward.Machine tool five axis processing, six axis processing has become more and more popular, machine tool processing compound already is inevitable development tendency.
