CNC is an automated machine tool controlled by a program. The control system is capable of logically processing programs with control codes or other symbolic instructions, decoding them through a computer, and thus causing the machine tool to move and process parts. The blank material is processed into semi-finished finished parts, etc. by tool cutting.
CNC machining has the following advantages.
1. A large reduction in the number of fixtures, the processing of complex shaped parts do not need complex fixtures. If you want to change the shape and size of the parts, you only need to modify the parts processing program, applicable to new product development and restyling.
2. Stable processing quality, high processing accuracy, high repeatability, adapt to the processing requirements of the aircraft.
3. Higher productivity in the case of multi-species and small-lot production 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 optimal cutting volume.
4 can be processed by conventional methods difficult to process complex surfaces, and even process some of the unobservable parts of the processing.
The disadvantage of CNC machining is that the cost of machine tools and equipment is expensive, requiring a high level of maintenance personnel.
