【Abstract】 The realization of the parameterized design & assembly in virtual environment for Parallel Machine Tool (PMT) is discussed. Based on the analysis of workspace of PMT, a new mathematical model of workspace is built and the parameterized calculation is realized, which increases the efficiency of interfere calibration. The simulation is made for the interfere calibration of cutter path and real-time 3D kinematics of PMT in the process of machining.更多还原
