The contact point regress method and error calculations mathematical model of the spatial cam profile inspection
Based on the CMM,the paper firstly proposes and analyzes a new contact point regress method,which adapts to measure any type of spatial cam profile.The coordinates of the measure point are regressed to that of the practical contact point of the cutter.This method realizes the measure of the practical profile of the spatial cam and establishes the mathematical model and error calculate method.In the end,a design example is present.This method will offer a new method for the inspection and error calculation of the spatial cam.
