A measure of probe radius compensation for CMMSUN Ke, TIAN Huai-wen School of Mechanical Engineering, SouthWest JiaoTong University, Chengdu 610031, ChinaAbstract:A practical probe radius compensation is described in this paper for CMM measurements of the surface data. Propose a strategy that refine the measureing points two times, interpolate of the measureing points along the measureing line, then interpolate of the cross-sections. After this, derive the horizontal and vertical shear vector of the refineing points using methods of interpolation and derivation, and then cross-product the two shear vectors to obtain the law vector of each refineing points, and compensate the probe radius in the end.[著者文摘]
