摘要
分析封闭圆柱凸轮槽结构,设计出专用夹具,实现零件在车铣复合机床上的快速装夹定位;使用UG NX4.0多轴加工功能编制出适合车铣复合加工机床的加工程序,提高了同类型凸轮零件的加工效率。提出沿曲面曲率进刀方法,解决了加工过程中因常规圆弧等进退刀方式引起的封闭圆柱凸轮槽内两侧面接刀痕的问题。经实际加工验证,采用该方法大大提高了零件的加工质量,降低了次品率。
The structure of closed cylinder cam slot was analyzed, a special tongs was designed to realize quick clamping and po- sitioning of spare parts in the mill-turn compound machine tool. By using UG NX4. 0 multi-axis process function, a process program suitable for mill-turn compound machine tool was written, and the processing efficiency of the same kinds of cam spare parts was im- proved. The feed method following surface curvature was put forward, and the problem about contact tool scars generated on the two sides inside the closed cylinder cam slot caused by normal feed methods was solved. It is verified through test that the process quality of spare parts is greatly improved, and the inferior rate is reduced.
