平面凸轮轮廓在数控铣床的磨削加工

Grinding Machining of Plane Cam Profile on CNC Milling Machine

本文以某公司铜线凸轮轮廓的磨削加工为例,经修整磨削,砂轮半径值吻合该凸轮的过渡半径值,采用$TC_DP6 [T,D]刀具半径补偿指令在数控铣床磨削加工程序中自动赋值。实际磨削加工证明,该凸轮轮廓的磨削加工工序合理,基于CAM自动生成程序,加入参数编程指令、$TC_DP6[T,D]刀具半径补偿指令磨削加工的方法可行、简便,确保了凸轮轮廓加工的质量及效率。

This paper takes the grinding process of a copper wire cam contour in a certain company as an example,and after adjusting and grinding the grinding wheel radius value to match the transition radius value of the cam,the use of $TC_DP6[T,D]tool radius compensation command is automatically assigned in the CNC milling machine grinding program.The actual grinding process has proven that the grinding process of the cam profile is reasonable.Based on the CAM automatic generation program,adding parameter programming instructions and $TC_DP6[T,D]tool radius compensation instruction grinding machining is feasible,which is simple and ensures the quality and eficiency of cam contour machining.
