Controlling the accuracy of manufacturing surfaces of parts by CNC machining centers

The high quality of base members of complex geometrical shapes with precise cylindrical surfaces is quite difficult to provide. Manufacturing accurate surfaces using CNC machines requires unconventional processing methods and, first of all, a reasonable strategy for stock removal during finishing operations. A method of ensuring the accuracy of precise surfaces of parts during CNC machining is developed. The proposed method is verified experimentally on samples made of a hard-to-treat material. The possibility of this method to ensure the required accuracy of diametrical sizes of surfaces corresponding to IT5 and IT6 in an automatic cycle is discussed.
