| Abstract: | This paper introduces the requirements of the radial feed system of non-circular turning,chooses the direct drive of linear servo motor and designs the structure of the feed system. It makes the analysis of mechanical properties on tool holder and work platform and analyses the cutting capacity of the feed system by velocity and acceleration characteristics of turning piston ring, oval and hexagon non-circular cross-section parts. The results show that the radial feed system of CNC lathe has frequency response characteristics, and meets the requirements of high speed non-circular turning. |
