高速铣削条件下耐磨功能表面的设计、表征与精确制造

For automobile cover mould, surface wear is one of the main failure forms. Because of the contradiction between various surface treatment technologies and the manufacturing process of automobile cover mould, the development of applications in manufacturing automobile cover moulds is limited. It has important research value and practical significance to improve the surface wear resistance and ensure the machining efficiency simultaneously. This project mainly for the actual service condition of automobile cover mould, determine the bionic designed prototype of function surface with high wear resistance and establish the initial model of characteristic parameter of the function surface structure. Study the generation mechanism of surface topography processed by high speed milling , conduct the high speed milling strategy reverse based on the function surface structure. Realize the numerical simulation of continuous stamping process for automobile cover mould, illuminate wear variation rule of the function surface. Optimize the function surface structure of automobile cover mould, characterize wear resistance of the function surface and propose a precise manufacturing method to realize it.For high speed milling automobile cover mould, the aim of this project is to conduct the researches on basic theories and implementation technologies of design, characterization and manufacture of the function surface with high wear resistance, and to provide theoretical and experimental data support for high-efficiency, high-performance manufacturing automobile cover moulds.
