advantage:
(1) Greatly reduce the number of tooling, machining parts with complex shapes does not need complex tooling. If you want to change the shape and size of parts, you only need to modify the part processing program, which is applicable to the development and modification of new products.
(2) The processing quality is stable, the processing accuracy is high, and the repetition 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 higher, which can reduce the time of production preparation, machine tool adjustment and process inspection, and reduce the cutting time due to the use of cutting quantity.
(4) It can process complex surfaces that are difficult to be processed by conventional methods, and even process some unobservable machining parts.
Disadvantages: machine tools and equipment are expensive, and maintenance personnel are required to have a high level.
