CNC Machining has the following advantages: ① a large number of reduced tooling, the processing of complex shapes and components do not require complex tooling. If you want to change the shape and size of the parts, only need to modify the parts processing program, suitable for new product development and modification. ② processing quality is stable, high processing precision, high repetition precision, to meet the requirements of aircraft processing. ③ has high production efficiency in many varieties and small batch production, can reduce the time of production preparation, machine tool adjustment and process inspection, and reduces cutting time due to the use of optimum cutting amount. ④ can process complex surfaces that are difficult to process by conventional methods, and can even process some parts that cannot be observed.
The disadvantage of NC machining is the high cost of machine tool equipment, requiring the maintenance personnel to have a higher level.
