圆柱凸轮的四轴联动加工与仿真技术

Four-axis Linkage Machining and Simulating Technology for Cylindrical Cam

圆柱凸轮是空间曲面结构,采用实体建模方式编程,建模过程复杂,编制时间长。研究了一种新的四轴联动编程加工技术,该方法利用CAM软件MasterCAM的缠绕功能,直接用二维曲线生成三维加工轨迹,程序后置处理后可直接送入机床进行加工具有简单实用的特点。加工实践表明,零件各项技术指标均达到设计要求,验证了该编程方法的可行性。

Cylindrical cam is the dimensional curved surface structure, it would be a complicated and time-consuming process if adopting the entity modeling. There is a innovative programming approach based on four-axis linkage motion which makes it possible to generate 3D tool path directly by a two-dimensional curve through winding function in Master- CAM. It is very simple and practical for programmer after post-processing sent directly into the machine with no modification. Throughout practical machining, all the technical indicators of the part satisfy with the demand for designer, which means that the approach is feasible.
