Modelling and simulation of the contour error evaluation based on spherically-approximated patches for freeform surface

Abstract: The mathematical modelling of contour error evaluation in Computer Aided Manufacture (CAM) system is critical for high-precision measurement and manufacture of free-form surface. The existing methods of evaluating the contour errorfor free-form surface have been developed based on various models. Nevertheless, there still exist some of the shortcomings when applied practically, including the inaccurate distance model between the measured point cloud (MPC) and ideal surface, numerical search required for the co… Show more
