摘要
Abstract
For the control of workpiece contour errors resulting from the change of workpiece posture,a matching algorithm based on on-machine measurement data is designed.The reference points on the theoretical and actual measured surfaces are selected to build local coordinate systems,and the initial matching is achieved by aligning the local coordinate systems.The objective function based on the least square method is established by the point sets after the initial matching.The optimal transformation matrix can be acquired by self-adaptive differential evolution algorithm.The posture adjustment matrix of workpiece can be achieved by the two matching results.The algorithm is verified through practical application.The results show that the designed algorithm can complete the adjustment of machining coordinate system,and contributes to the effctive control of contour errors.关键词
