Abstract

The purpose of this paper is to present an experimental work attempting to optimize the influencingprocess parameters involved in dry machining of the exhaust engine valve of material martensiticstainless steel grade SUH3. Looking at available literature it is observed that a lot of work can be donein the field dry machining related to surface integrity but no work can be reported on investigationimplementation of dry machining in engine valve manufacturing of martensitic stainless-steel of gradeSUH3. In this work Aluminum Tin Nitride (AlTiN) coated carbide cutting tool is used for machiningoperation in dry condition.AlTiN coated carbide cutting tool best suitable for dry machining operationto achieve the required output measure. The experiments were carried out on experimental set updeveloped in machine shop. Response surface methodology (RSM), employing a Box–Behnken designfor three design variables such as cutting speed(vc), feed(f), depth of cut (ap) was used to assess theprocess performance with the help of 15 experimental run. Minitab 17 soft wear is used in theexperiment for set up of experimental trial. In this experiment Analysis of variance (ANOVA) is usedfor checking the consistency of the cutting parameters. Regression based models for the responseoutputs were obtained and residual plots is used as graphical representation of analysis done duringexperimentation which show the effect of cutting parameters like cutting speed, cutting feed and depthof cut with the help of various residual plots.
