Abstract

Hard turning of martensitie stainless steel is gaining importance in all manufacturing sectors like automobile and aerospace industries. Machinability of materials depends on surface roughness, tool wear, cutting forces, specific cutting pressure and work material hardness. In this paper, hard rnartcnsitic stainless steel AlSl 440 C md SCM 440 alloy steel was used as work piece materials. CBN and PCBN eutting tools were used to turn these work materials. The operating parameiers used were cutting velocity 100, 125, 150, 175 and 200 mlnlin with feed rate of 0.10, 020 and 0.30 mrn11.e~w ith constant depth of cut of 1.0 mm. The length of turning was 150 mm and 750 mm. Machitlability of both nlaterinls and both tools were evaluated in terms of roughness, flank wear, cutting force and specific cutting pressure.
