基于线接触的回转二次曲面加工仿真研究

Process Simulation of Line Contact Machining of Revolution Conic Surfaces

根据线接触加工回转二次曲面基本原理,建立基于磨粒磨损理论的线接触加工过程仿真模型,给出仿真流程并分析仿真过程各项参数的选取方法,最后基于此模型来研究加工参数如磨粒大小、工件初始面形和刀具初始面形对加工结果的影响,仿真结果表明工件和刀具初始面形对加工结果没有影响。

A program to simulate the process of line contact machining of revolution conic surfaces is described.The program is based on the theory of the grain-abrasion.With the analysis of the grinding contact system,the material removal model is made.Given the flow chart of the simulation procedure,the methods for choosing the simulation parameter are discussed.To verify this model and to analysis the machining process,the effect of machining is discussed,such as size of particle,initial shape of the workpiece and initial tool shape on the final shape of the workpiece with this model.The simulation results indicate that the final shape is independent on the initial shape of the workepiece.
