CNC machining has the following advantages:

① 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.

②Stable processing quality, high processing precision and high repeatability, which can meet the processing requirements of aircraft.

③ 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 reduce the cutting time due to the use of the optimal cutting amount.

④ It can process complex profiles that are difficult to process by conventional methods, and even process some unobservable processing parts.

The disadvantage of CNC machining is that the machine tool is expensive and requires a high level of maintenance personnel.
