Abstract

This research tries to find a meeting point that will reduce regenerative chatter which is a prolonged form of chatter under control by modeling the machining process using first order least square full discretization method. A mathematical model was developed to assist to locate the productive spindle speed at which the lobbing effects occur and depth of cut combination for the machinist. Computational algorithm was developed for the purpose of delineating stability lobe diagram into stable and unstable regions. The results show considerably smooth milling which will be of immense benefit to machinist in choosing the route to follow in machining oppression.
