摘　　要：针对空间斜孔加工容易产生偏差的问题,建立了以立方体上任意两点空间直线为对象的零件模型,以机床附件铣头带动刀具倾斜与工件倾斜相结合的复合加工模型。根据投影关系,推导出了加工空间斜孔所需要的斜角计算公式,建立了任意空间角度斜孔加工的数学空间模型。给出了几种具体的斜孔加工方法并将结果成功应用于生产实践,取得了显著效益。Aiming at the problem that the space bevel hole machining is prone to deviation,a part model is established,which take's any two points space line on the cube as the object,and a compound machining model is set up,in which the tool inclination and the workpiece inclination are driven by the rain head of the accessory of the machine tool.According to the projection relation,the bevel formula for machining space bevel hole is derived,and the mathematical space model for machining arbitrary space bevel hole is established.Several methods for machining inclined hole are given and the results are successfully applied to production practice.
