EXPERIMENTAL STUDY OF SURFACE ROUGHNESS AND CUTTING FORCES ON STAINLESS STEEL GRADE MATERIALS

This paper focus on monitoring of surface roughness and cutting forces while machining on two different grade stainless steels under dry and mist conditions. Stainless steels like AISI 304 and AISI 316L are considered for study. Process variables like workpiece speed, tool feed and depth of cut are taken for experimentation on CNC lathe. Responses like surface roughness, power consumption and cutting forces are predicted while machining on the two different stainless grades under dry and mist. Taguchi design of experiments is considered for experimental design. Signal-to-noise ratio of the responses are used for determining individual optimization, while Analysis of Variance is used for knowing significant effect of process variables over the generated responses. This paper shows novelty of using power consumption for calculating cutting forces and also comparisons of two different stainless steel grades simultaneously under dry and mist conditions. In addition, comparison of AISI 304 material with two different diameters is also studied
