CNC is the abbreviation of numerical control, also known as computer gong, which is an automatic machine tool controlled by a program. The control system can logically process the program specified by the control code or other symbolic instructions, and decode it through the computer, so that the machine tool can perform the specified action, and the rough material can be processed into semi-finished finished parts by tool cutting. CNC machining is a new type of machining technology. The main job is to compile machining programs, that is, to convert the original manual work into computer programming.
The composition of CNC system:
The CNC system consists of "numerical control device", "servo system" and system program.
.CNC device (special computer): hardware and software components.
.Servo system: It consists of detection device, drive device and servo motor.
CNC machining has the following advantages:
The number of tooling is greatly reduced, and complex tooling is not required to process parts with complex shapes. If you want to change the shape and size of the part, you only need to modify the part processing program, which is suitable for new product development and modification.
The processing quality is stable, the processing precision is high, and the repeatability is high, which is suitable for the processing requirements of aircraft.
The production efficiency is high in the case of multi-variety and small batch production, which can reduce the time for production preparation, machine tool adjustment and process inspection, and the cutting time is reduced due to the use of the best cutting amount.
It can process complex profiles that are difficult to process by conventional methods, and even process some unobservable processing parts.
Commonly used CNC CNC systems for machining centers include: Japan's Mitsubishi system, Japan's FAUNC system, Germany's Siemens system, Taiwan's new generation system with Japan's Yaskawa feed system
