The advantages of CNC numerical control.

① Significantly reduce the number of tooling, and complex-shaped parts no longer require complex tooling for processing. If the shape and size of the parts need to be changed, only the part processing program needs to be modified, which is suitable for new product development and modification.

② The processing quality is stable, the processing accuracy is high, and the repeatability accuracy is high, which meets the processing requirements of aircraft.

③ In the case of multi-variety and small-batch production, the production efficiency is relatively high, which can reduce the time for production preparation, machine tool adjustment and process inspection. Moreover, due to the use of the optimal cutting parameters, the cutting time is also reduced.

④ It can process complex surfaces that are difficult to machine by conventional methods, and even some processing parts that cannot be observed.

The disadvantage of numerical control machining is that the machine tools and equipment are expensive and require maintenance personnel to have a high level of expertise.
