摘　　要：为克服车轮检测误差造成的过度镟修,采用逆向工程三维检测原理,对火车轮磨损件进行表面信息获取,提取特征参数建立标准车轮模型。通过3D分析比对,精确检测出车轮各尺寸参数的磨损程度,根据3D检测报告确定初步镟修方案,并在检验镟修方案的同时对其优化,最终制定出最佳镟修方案,避免由于检测误差引起的车轮轮缘及踏面的过度镟削,达到有效节约成本的目的。To overcome wheel detection error caused by excessive lathing,3D detection principle of reverse engineering is used to get information of the worn wheel＇s surface and extract feature parameters in this paper,then the standard wheel model is modeled.The degree of wear of each size wheel is accurately detected by 3D analysis and comparison.The initial lathing program is determined according to the 3D detection reports and optimized when testing the lathing program,and finally the best lathing program is worked out to avoid the over lathing cut of the wheel rim and tread caused by detection error and to save cost effectively.
