刀具切削角度的通式

金属切削刀具广泛地应用于机械制造业中，随着加工对象和生产条件的不同，刀具的切削角度更是千变万化。然而到目前为止，各种刀具的切削角度竟没有一些通式来表示其变化规律。本文根据切削速度方向以及刀刃和刀具表面法线方向，推导了刀具切削角度的一些通式，利用这种通式可以方便地确定任何复杂刀具的切削角度。

GENERAL FORMULAS OF TOOL CUTTING ANGLES

The metal cutting tools are widely employed in machinery manufacturing industry, and the cutting angle of the tools is intricate and volatile owing to the difference of workpiece and the production conditions. But to date there are scarcely any general formulas used to express the regularity of variation for the cutting angle of different cutting tools. In this paper some general formulas of cutting angle are derived in consideration of the direction of cutting speed and the direction of cutting edge and surface normal of fools-By means of these formulas the cutting angle of any complicated tools can be calculated with convenience.
