摘要

车齿工艺是一种高效齿轮切削加工工艺，刀具工作角度是影响切削加工性能的重要参量。车齿工艺由于运动关系和刀具几何形状复杂，导致刀具工作角度在切削过程中不断变化，并受多因素影响。首先基于车齿工艺原理和坐标变换方法建立其运动学模型，并根据车齿刀几何构型建立产形后刀面、前刀面和切削刃的数学模型，结合斜角切削的刀具工作角度定义推导出车齿刀工作前角和后角的计算公式，实现车齿刀工作角度演变过程的解析表示，最后分析了车齿刀设计前角和螺旋角对工作角度的影响。结果表明较大的刀具设计前角主要影响工作前角，而车齿刀螺旋角主要影响工作后角。相关结果可以为刀具结构优化提供理论支撑。

Abstract

Gear skiving is an efficient gear cutting technology，and the tool working angle is an important parameter affecting the cutting performance. Due to the involving complex kinematics relation and cutting tool geometry in skiving process，tool working angle changes continuously and is affected by several factors. Primarily，the kinematics model is established based on gear skiving principle and coordinate transformation method. And the mathematical model which specifying the forming flank，rake face and cutting edge of the skiving cutter is proposed according to the geometric configuration of skiving cutter. The calculation formulas of the working rake angle and relief angle of the skiving cutter are derived by bringing in the definition of tool working angle in oblique cutting model. It is capable of realizing analytically express the evolution process of the working angle of gear skiving cutter. Finally，the influence of the designed rake angle and the helix angle of the skiving cutter on the working angle is analyzed. The results show that the designed rake angle tends to affect the working rake angle，while the helix angle of skiving cutter is more conducive to the relief working angle，and the analysis results can provide theoretical support for tool structure optimization for skiving cutter.
