HPT Process Parameter Optimization in Dry Turning of Bohler K110 Steel

This paper presents the optimization of surface roughness & material removal rate in hard part turning (HPT) of Bohler K110 steel. Carbide inserts were used for machining of Bohler K110 to study effects of process parameters [Cutting speed (S), Feed (F) and depth of cut (D)]. These models can be effectively used to predict the surface roughness (Ra) & material removal rate of the work piece. The big challenge of the Micro, small & medium industries in India is to achieve high quality products with increased productivity with minimal setup. Paper presents work of an investigation of HPT process parameters on Bohler K110 material, for optimization of surface roughness, material removal rate for avoiding cylindrical grinding operations. The experiment is carried out by considering three controllable input variables namely cutting speed, feed rate, and depth of cut. The design of experiment and optimization of surface roughness, material removal rate is carried out by using Taguchi L9 orthogonal array. Affirmation of the results was done with dry and wet machining. (C) 2015 Elsevier Ltd. All rights reserved.
