推导了准双曲面齿轮小轮数控变性法铣齿加工各数控轴的运动表达式,在VERICUT环境中,以一对准双曲面齿轮副的小轮为例,建立其数控铣齿模型,利用SIMENS数控系统中的计算参数R编制通用的小轮粗切和变性法精切的数控程序,进行了包括粗切和变性精切的小轮加工全过程仿真。

英文摘要：

NC axes motion expressions of hypoid pinion NC machining by the modified roll are derived.Using NC machining simulation software,VERICUT—the virtual simulation machining model of the hypoid pinion of a pair of hypoid gears is modeled,and universal NC program consist of rough-machining and finishing cutting are done by application calculation parameters R in SIMENS numerical control system,then the whole hypoid pinion NC machining process is simulated.
