| Abstract | This paper investigates the High speed end millin g of Al-Si-Mg-Fe alloy for aerospace and automotive industry. High speed machining has received important interest because it leads to an increase of prod uctivity and a better workpiece surface quality. At high cutting s peeds, the tool wears increases dramatically due to the high temperature at the tool-workpiece interface. The cu tting force depends upon the cutting speeds, depth of cuts and feed rates. The behavior can be attributed to the p recipitation hardening in the alloy on account of t he formation intermetallic compounds. The cutting force increase s with increase in feed rate and depth of cut. The machining parameters with the highest influence on tool wear progress are cutting speed and feed/tooth. Tool wea r impairs the surface finish and hence the tool life is reduced. The cutting speed range was up to 1800 m/min. The feed rate used was up to 5000 mm/min. Cutting speeds of up to 1800 m/min are feasible and will greatly improve the mi lling process productivity and to implement this range of cutting velocity in industrial applications, new c utter designs should be developed.The adhesive tool wear mechanism and adhesion activated surface quality deteriorat ion are revealed. Chip management is indicates that up to a cutting speed of 1800 m/min, a continuous chips ar e generated and cause surface degradation. |
