Thermal analysis & Optimization of coated turning insert on AISI 304 Austenitic stainless steel materials-A Review

Austenitic stainless steels are a mostly used group among stainless steels. The austenitic stainless steel is consumed in large volumes (72%) among the other grades of stainless steels. Many of research works contributed their efforts to overcome poor mach inability of austenitic stainless steels. Many problems have been faced by users during machining due to its low thermal conductivity, high work hardening, high strength, and high ductility. These made it complicated to machine the materials. The aim of our present experimental investigation is to study the temperature analysis and to determine the optimal levels of process parameters for optimizing the surface quality of AISI 304 austenitic stainless steel work piece by employing Taguchi's orthogonal array design and Analysis of Variance (ANOVA) using PVD coated turning insert tool on CNC lathe. Taguchi's Design of Experiments approach (DOE) is used to analyze the effect of process parameters on surface roughness to obtain their optimal setting. The ANOVA is used to identify the significant process parameters more accurately by investigating the relative importance of process parameters. This paper deals with the study of the performance of coated turning insert in turning AISI 304 austenitic stainless steel material.
