With the development of the manufacturing industry and the progress of science and technology, all walks of life, especially in aerospace, medical, automotive, electronics and other fields, the requirements for metal precision parts are getting higher and higher, and the precision, difficulty and complexity of metal precision parts are also gradually improving. Compared with the ordinary metal processing technology, the processing accuracy and surface finish of the precision metal processing technology are higher than the corresponding processing methods. Precision machining technology generally includes precision machining, such as diamond boring, precision turning, wide-edge precision planing, etc., and high-precision grinding. The processing accuracy of precision machining is generally......
