| 摘 要： | 基于贝塞尔方法提出了针对自由曲面的自适应测量算法,并与传统测量方法进行了对比。在对自适应测量数据的处理中,提出了一种新的基于离散点三角剖分的测球半径三维补偿算法。通过仿真和试验验证,上述算法已成功应用于集成化柔性激光加工系统中。

| Abstract: | A 2D adaptive measure method for free surfaces based on Bezier curves is developed, the measuring experiments are carried out focused on comparison of our new method with traditional equal step measuring. In order to process the scattered data from adaptive measuring, a 3D probe compensation method based on triangulation has also been developed, both compute simulation and practical experiments are performed, and the results show potential application of the methods in the laser intelligent manufacturing system. |
