Based on the analysis of existing CMM measuring path planning algorithms, a kind of planning method of CMM measuring path is proposed based on the known CAD model and vector resemble selection algorithm. This algorithm can select appropriate measuring points to create the measuring path and DMIS program according to the curvature relationship between vicinity points. Then a simulation verify platform for DMIS program is set up. The experiment proves that the DMIS program verified and debugged by simulation can be used to CMM measurement directly, and the CMM measuring efficiency and accuracy can be improved greatly.
