摘　　要：为了使复合修整方法中的多种工艺更系统地整合,提高成形砂轮的修整效率,结合自主研制的激光–机械复合修整装备,开发一套CAM系统,可根据不同砂轮截面形状,自动规划多工艺、多修整策略下的修整轨迹,计算平面三轴联动修整刀路,自动生成加工代码,同时设计可视化界面仿真加工过程。对青铜结合剂金刚石砂轮进行修整试验,结果表明:该系统可在保证机床不发生碰撞和过切的情况下,生成激光粗修、半精修及机械精修的加工程序,大幅提高复合修整方法的编程效率,修整后的砂轮轮廓误差在9.1μm以内,圆跳动误差为6.1μm。In order to integrate various processes in composite dressing method more systematically and improve dressing efficiency of forming grinding wheel,a CAM system was developed by combining self-developed laser and mechanical composite dressing equipment.According to different grinding wheel section shapes,the system can automatically plan dressing trajectory under multi-process and multi-dressing strategy,calculate planar three-axis linkage dressing tool path,automatically generate machining code,and design visual interface to simulate machining process.The dressing experiment of bronze bonded diamond grinding wheel was completed.The results show that the system can generate laser rough repair,semi-finishing repair and mechanical finishing machining program without collision and overcutting,and greatly improve the programming efficiency of composite dressing method.After dressing,the grinding wheel profile error was within 9.1μm and the runout error was 6.1μm.
