Chatter suppression analysis in milling process with variable spindle speed based on the reconstructed semi-discretization method

Within the scope of high speed milling process parameters, analyzed and discussed the effects of spindle speed, feed rate, milling depth and milling width on milling forces in the process of high speed milling of AM50A magnesium alloy. At the same time, the influence of milling parameters on the surface roughness of AM50A magnesium alloy has been revealed by means of the measurement of surface roughness and surface micro topography. High speed milling experiments of AM50A magnesium alloy were carried out by factorial design. Form the analysis of experimental results, The milling parameters, which have significant influence on milling force in high speed milling of AM50A magnesium alloy, are milling depth, milling width and feed speed, and the nonlinear characteristics of milling force and milling parameters. The milling force decreases with the increase of spindle in the given mill parameters. For the effects of milling parameters on surface quality of the performance, in the milling depth and feeding speed under certain conditions with the spindle speed increases the surface quality of AM50A magnesium alloy becomes better with the feed speed increases the surface quality becomes poor. When the spindle speed is greater than 12000r/min, the milling depth is less than 0.2mm, and the feed speed is less than 400mm/min, the milling surface quality can be obtained easily.

Milling Condition

Milling process is the removal of unwanted materials so as to produce the required shape. The purpose of this study was to investigate the effect of milling process parameters and the cooling technique on corrosion behaviour and microhardness of TI-6AL-4V. Milling of Ti-6Al-4V was carried out using tungsten carbide cutting tool while varying spindle speed (120,150, and 180 rev/min), depth of cut (1, 1.5 and 2 mm) and the feed rate remained unchanged at 4.6 mm/min. Subsequent to milling, characterization of subsurface microhardness and corrosion behaviour was conducted. It was found that varying spindle speed and depth of cut had an impact on microhardness. Furthermore, it was noticed that the type of milling condition (flood and dry milling) affected the subsurface microhardness and the corrosion behavior. The corrosion resistance of the milled surface was generated at 180 rev/min and 150 rev/min for the dry and flood milling respectively. Furthermore, the most corrosion resistance was obtained at 2 mm and 1.5 mm depth of cut during dry and flood milling respectively.
