摘要： 为了精确测量砂轮轮廓，分析了一种曲线磨削砂轮廓形快速原位视觉检测的工作原理，设计了砂轮廓形原位视觉检测系统，提出了砂轮廓形精度的测量和量化评定方法.基于自主研发的曲线磨削平台，通过实验验证了砂轮廓形原位视觉检测系统的测量精度.同时，为了提高工件的加工精度，进一步提出了一种砂轮廓形误差的分段量化表征和误差补偿方法，并进行了实验研究.结果表明，所提出的方法能够实时在线补偿砂轮廓形误差，有效提高零件加工轮廓的形状和尺寸精度.

Abstract: This study introduced a method for a rapid vision detection of edge profile of grinding wheel based on a self-developed profile grinding machine. The in-situ vision detection of wheel profile was designed. The accuracy measurement and quantitative assessment of wheel profile were presented. The feasibility and measurement accuracy were experimentally testified. Finally, a segmented quantitative characterization of wheel profile error and error compensation method were proposed for grinding of contour surfaces. Experiments were designed and conducted. The experimental results indicated that the method can online compensate wheel profile error and effectively improve the shape and size precision of profile of machined component.
Key words: wheel profile; profile curve grinding; vision detection; wheel wear; error compensation
