汽车覆盖件模具数控加工刀具轨迹规划系统

A System of Planning the Tool Path for NC Machining Dies of Motor Covering Parts

为降低数控加工的成本 ,提高生产效率 ,必须对刀具运动轨迹进行合理规划。为此提出了构成汽车覆盖件表面的各种典型曲面 (旋转面、直纹面、列表柱面、自由曲面等曲面 )的刀具轨迹的规划方法 ,建立了刀具轨迹的规划系统。

To reduce the cost of NC machining for raising the production efficiency the movement path of NC tools must be planned reasonably A method is proposed for planning the tool path various curved surfaces composing of motor covering parts including rotating surface,ruled surface,list cylindrical surface,free surface and constant surface A system for planning the tool path is developed
