普通车床横向切断车刀工作后角变化规律及控制措施

Change Principles and Controlling Measures of working orthogonal Clearance of Horizontal Cut-off on Center Lathe

在普通车床上横向切断轴类零件是车削加工的基本工艺.通过对横向切断车刀工作后角变化过程的分析,表明工作后角的变化规律,指出在实际切断中为避免工作后角变负,采用手动进给是目前唯一有效的方法。

Horizontal cut-off tool on center lathe is fundamental technique in lathe work,and it is shown that through analysis of changing process of horizontal cut-off,it is the only method to use manual impulse to avoid negative working orthogonal clearance according to the principles.
