A Literature Review on Optimization of Cutting Parameters of P20 Steel by Using Taguchi Method for Minimizing Surface Roughness in End milling Process

The Surface roughness is one of the most commonly used criteria to determine the quality of milled steel and it is affected by various cutting parameter such as depth of cut, cutting speed and feed rate. Surface roughness is an important parameter for quality of product such as aerospace, automobile and mold dies etc. Some standard tools and techniques are required for the analysis of cutting parameter to get the optimum results. Surface roughness contributes to better function or longer life span. It also contributes to abrasion resistance materials and good wear resistance. Hence Taguchi method or cutting parameter design approach is used. The aim of the project is to optimize the cutting parameter such as feed rate, depth of cut and cutting speed for End milling process of P20 steel. P20 steel which is used for making molds and dies requires excellent surface finish. This can be achieved by Taguchi method aiming to increase the surface finish and reducing production cost. Taguchi method is powerful tool to design a process. It can be used to find optimal condition for the operation. This optimized cutting parameter can be used for End milling process to achieve better surface finish.
