The results show that the effects on surface roughness are feed speed, depth of cutting , tool rake angle and parts hardness in turn.
结果表明：工件进给速度对表面粗糙度的影响最大，切削深度和刀具前角次之，工件硬度影响最小。

The effects of tool's inclination angle on chip formation and the temperature fields, as well as the cutting forces, back forces and feed forces are discussed.
通过三维切削模拟可以获得在不同刃倾角精密切削过程的条件下切屑形状、切削力和切削温度场的分布情况。

In this system the crankshaft rotating Angle, where the peak combustion pressure occurs, is taken to be a feed back signal, so that the ignition timing of the engine is able to be controlled.
