Tool life has been a major source of concern to manufacturers, the extent of usefulness of any tool depends on it. The major cause of tool failure is tool wear and the most important aspect of wear to a machinist is the flank wear as it is the flank that is in direct contact with the work piece. This research investigates various cutting parameters and how they contribute to tool wear. The model used is the new wear model proposed by Palmai. The research involved the experimental investigation of turning on the Sumore SP 2110 lathe machine using ISOP Tungsten Carbide and High Speed Steel (HSS) as tools and Bright Mild Steel and Stainless Steel as work piece. The experimental data were used to calibrate the Palmai model for the various cutting tool and work piece pair, at different cutting parameters of spindle speeds depth of cut and feed rate. Experimental and Paimai wear results show good correlation, with about 1.5% to 5.4% deviation.
