Experimental investigation of surface roughness and cutting force during machining of SS43100 by using coated and uncoated carbide inserts

Abstract

Machining processes are the accurate metal removal processes for shaping components in the manufacturing industry. The main challenges of the manufacturing industry are to increase productivity and quality. Manufacturing industries are trying to reduce the cost of machined parts which are manufactured by different machined methods. Machining hard metals is a challenging task. In the presented research work machining parameters were investigated for machining of SS43100 by using coated and uncoated carbide tool inserts. Carbide tool inserts were coated by Ti16Zr using the PVD method of coating. Experiments were performed during the turning operation of SS43100 by coated and uncoated tool inserts. Cutting speed range were 150r.p.m, 250 r.p.m., 350 r.p.m., feed were 0.085 mm/rev, 0.095 mm/rev, 0.1 mm/rev. and depth of cut was 0.1 mm, 0.15 mm, and 0.2 mm selected as controlling factors. Surface roughness and cutting force were selected as response factors. Digital lathe tool dynamometer was used for cutting force measurement and ITI surface tester RS232 was used for surface roughness measurement. In the experimental study and analysis of output response parameters, Taghuchi L9 orthogonal array model has used The results obtained were optimized using the Taghuchi technique for cutting forces and surface roughness. The Taghuchi technique was performed for combinations of each input variable in linear fit model multivariate analytics. Experimental results were compared and models established supported by evidence.
