Problems solved by technology

[0002] In the NC process of turning, the NC instructions for simple revolving bodies are generally directly constructed manually. For irregular streamlined revolving bodies, due to the lack of fixed mathematical equations, manual construction cannot be realized, and a dedicated NC turning module is required for NC instructions. Construction, during the construction process, parameters such as the front and rear angles of the turning tool also need to be considered. The construction process of CNC commands is cumbersome and low in efficiency, resulting in complex CNC turning operations and low efficiency for irregular streamlined rotary bodies
