Applied Study On High-speed Milling Hardened Steel

The HSC (high-speed cutting ) technique has much excellence, for example, the cutting action effectiveness, The process quality is high, Be able to directly process quench stiff steel and well economy, So The HSC technique has been turned into important developmental direction of advanced manufacture technique today. Along with the development of HSC technique, it is able to afford effective passes for processing quench stiff steel. But, The HSC is one kind of bran-new cutting means, the holistic technique level of the researches in this field is not tall in our country, at present, we have no integrated parameter to supply selection and no much artifactitious example to supply references and no right ways in selecting machining tools. Otherwise, numerical control programme technique is not adapt to demand of HSC, we need right programme strategy to resolve these problem in numerical control system.Base on the origin of HSC technology and the mechanism, virtue and shortcoming, key technique of high-speed milling quench stiff steel. The paper mainly discourse upon the project of process technics and the right ways in selecting machining tools and the programme strategy to high-speed milling hardened steel. The main research finding is as follows:(1) The paper systemic discourses upon the mechanism, definition of HSC and the characteristic of high-speed milling quench stiff steel, It puts forward the problem of high-speed milling hardened steel and high-speed milling hardened steel is indispensable and feasible.(2) The paper systemic studys the technologic system of high-speed milling hardened steel. Across-the-aboard discourses upon the select project of machine tools, cutting tools, fixing and CAM software system.(3) Base on academic analysis and experimentation, it systemic discourses upon the parameter of process technics and offers some data and diagrams of HSM.(4) It puts forward the project of process technics and programme strat-egy of high-speed milling hardened steel.(5) According to the analysis of a representative example which the HSM technique applies in machining hardened steel mould, it confirms the application preponderance and foreground of high-speed milling hardened steel.
