微细轴正交车铣加工外圆表面形成研究

Study on Mechanism of Micro-shaft Surface Formation in Orthogonal Turn-milling Machining

车铣技术是以铣削方式实现车削功能,由于其特殊的运动方式,特别适用于微细轴类零件的外圆加工。为了研究正交车铣加工轴类零件外圆表面的形成过程,在建立铣刀刀刃与工件之间运动关系的基础上,运用计算机仿真模拟了刀刃的运动轨迹,结果表明轴类零件外圆表面是铣刀刀刃运动轨迹包络而形成的。同时通过对切削试验结果观察,验证了仿真运动轨迹的正确性。

The turn - milling technology realized the turning function through the milling. The technology may be employed in micro- shafts processing by the special movement mode. It sets up the motion relationship of the edge of end milling cutter and workpieces for analyzing the micro - shafts surface formation in orthogonal turn- milling machining. Through computer simulation, the results indicate that the formation of cylindrical surface of micro - shaft parts is enveloped by moving path of the edge of end milling cutter. The correctness of the simulation is demonstrated by cutting experiment.
