摘要
根据并联机床工作空间的定义及几何约束条件 ,提出了工作空间快速定位校验算法和许用平台倾角[β]x ,y ,z 的概念 ,论述了用许用平台倾角 [β]x ,y,z 组成的工作空间文件描述并联机床不发生干涉的工作空间的思想。在此理论基础上 ,利用VC6 .0开发了并联机床刀具轨迹干涉校验模块 ,该模块实现了对UG的CAM模块产生的刀具路径进行快速校验的功能。同时 ,应用OpenGL 。
According to the workspace definition and geometrical constraints of a parallel machine tool, a quick calibration algorithm and a concept of allowable platform obliquity [β] x,y,z are put forward, and the file made up of [β] x,y,z is used to describes the 5-dimension workspace of PMT. Then a quick interference calibration module of cutter path is developed with VC and a quick interference calibration of cutter path generated by the CAM module of UG is realized. Meanwhile, simulation is performed for interference calibration of cutter path and real-time 3D kinematics of PMT in the process of machining.
