摘要
通过采用一种新型的试验装置,可重现在了较大的切削速度范围内(从15~ ̄100m/s),正交切削下的切削过程。该试验设备可以记录在正交切削下的切削过程中法线方向上和切线方向上的作用力数值。从而在很大的切削速度范围内,可以对刀具和切屑之间的摩擦力进行分析。给出了切削力的分力变化和摩擦系数变化的情况。此外,通过可以使用一台高速摄影机,记录了高速加工中,切屑的形成过程的图像。
An original experimental device is used to reproduce conditions of orthogonal cutting for a wide range of cutting speeds(from 15 to about 100m/s). The device makes it passible to record both values of normal and tangential forces in orthogonal cutting. A n analysis of the tool-chip friction is then possible for a large range of cutting speeds. The evolution of cutting force components as well as the evolution of the friction coefficient are presented and analyzed. In addition, the process of chip formation during high speed machining is illustrated by photographic recording with a high speed camera.
