【 摘 要 】

This paper presents dry turning performance of coated carbide Tool on 17-4PH stainless steel bright bar (Aerospace metal), which is high strength and extremely corrosion resistant. The presence of different alloying elements and their precipitation hardening makes it a difficult to machine material.17-4PH metal available at different properties based on heat treatment conditions. But the base metal coming from mill is 17-4PH condition A, which is having hardness of 35RC. Cutting Tool Insert (KCP10B) is a specially engineered cobalt enriched carbide grade with thick MTCVD-TiCN-Al2O3-TiOCN coating for maximum wear resistance. The input parameters considered for this experiment are Velocity (V), feed (F) and Depth of cut (d). In this study, the influence of cutting parameters are aimed when turning 17-4PH condition A SS bright bar with KCP10B tool on a CNC Lathe (Maxturn plus+) without coolants. It is optimized that the Material Removal Rate (MRR) and cutting Forces (F1, F2) generated during dry turning of hardened steel (17-4PH) using carbide insert in a possible range of selected parameters by using TAGUCHI and ANOVA.
