First, a large number of reduction in the number of tooling, machining complex parts do not require complex tooling. If you want to change the shape and size of parts, you only need to modify the parts processing program, which is suitable for the development and modification of new products.
Second, the processing quality is stable, the processing accuracy is high, and the repeat accuracy is high, and it can meet the processing requirements of the aircraft.
Third, multi-variety, low-volume production conditions in the production of high efficiency, can reduce production preparation, machine tool adjustment and process inspection time, but also because of the use of the best cutting amount and reduce the cutting time.
Fourth, can process conventional methods difficult to process the complex surface, and can even process some unobserved processing sites
The disadvantage of CNC machining is that machine tool equipment is expensive and requires maintenance personnel to have a high level
