A Study on Transition of Dimension Error and Surface Precision in High Speed Endmill Cutting of Al6061S-Alloy

High speed machining aims to raise the productivity and efficiency by making more precise and higher value-added products than other machining method by means of the high speediness of spindle and feed drive system. The purpose of this study is to investigate the effects of the run-out of endmill on the dimension precision of workpiece and to obtain the fundamental data on high speed machining, which is available by machining the side of Al-alloy with solid carbide endmills in high speed machining center and by measuring dimensions and surface roughness. From the results of experimentations followings are obtains; if spindle speed is ultrahigh in conditions that radial depth of cut and feed per tooth are very small, highly precise and accurate products are to be made efficiently with feed rate and so we can raise productivity.
