Pilot Study Of High-speed Milling Process Parameters Optimization

The high-speed milling(HSM) of aluminium alloys is one of the important applied fields of application of high-speed milling technology. The optimization of cutting parameters which is relation to machining efficiency and machining economization is an significant research direction, and is one of the object of studying mechanism and technics on high-speed machining. This paper optimized the high-speed milling parameters for two kinds of aluminium alloys and two kinds of composites by applying the method of experimental optimization. First using orthogonal array for multi-factor analyses the effect of each factor in high-speed milling, then adopting a series of single factor experiments to propose by adjusting the tool length so as to take advantage of stability lobe effects. And lengthening the tool improves the metal removal rate. Following, obtaining the stability lobe diagrams of three materials and discussing the change mechanism of chip morphology during three machining states. The main factors which affect the tool wear and cutting temperature is also tested and the cutting temperature conversation law is validated. At last, the residual stress of the optimized areas is contrasted to other areas.
