① The number of tooling is greatly reduced, and complex tooling is not required for machining parts with complex shape. If you want to change the shape and size of parts, you only need to modify the part processing program, which is suitable for new product development and modification.
② It has stable processing quality, high processing precision and high repetition precision, and can meet the processing requirements of aircraft.
③ In the case of multi variety and small batch production, the production efficiency is high, which can reduce the time of production preparation, machine tool adjustment and process inspection, and reduce the cutting time due to the use of the best cutting amount.
④ It can process complex surfaces that are difficult to be processed by conventional methods, and even process some unobservable machining parts.
The disadvantage of CNC machining is that the cost of machine tool equipment is expensive, and the maintenance personnel are required to have a high level.
