螺旋锥齿轮数控加工过程中,用直廓截形代替盘状铣刀刀刃理论截形的偏差影响螺旋锥齿轮齿面加工精度. 在分析了螺旋锥齿轮数控加工原理这一基础上,建立了刀刃到形成齿面的数学模型;依据空间啮合理论计算盘状铣刀刀刃实际截形,分析并建立了盘状铣刀刀具半径误差与齿面的误差的关系;进一步通过加工工件齿面点反算推导出刀具实际截形误差,对实际的螺旋锥齿轮加工过程中齿面精度的提高具有重要的指导意义.

The deviation of the profile that cutter blade use a straight profile to instead the truly, that will impact the machining accuracy of spiral bevel gear tooth surface, during CNC machining process. This pa-per analyzes the principle of CNC machining spiral bevel gear first, and then a base on that build a mathe-matical model of the blade to the tooth surface;after that based on the space meshing theory to calculate the actual cutter blades;forward to analyze and establish the relationship of cutter radius affect tooth flank er-rors;finally, deduced actual tool profile error. This study will be important guiding significance to improve the accuracy of spiral bevel gear tooth surfaces.
