Experimentation and Optimization of Milling Machine Parameters Using Taguchi Method

Abstract

In this research work, the problem is to reduce the surface roughness of the Jacquard body which is a casting part to optimize the effects of different process parameters of surface roughness & to reduce surface roughness for milling operation by using the Taguchi method. Milling is better than other machines in the surface finish and accuracy. Greater quality product and higher productivity is the main vision of every entrepreneur. To achieve this, the process parameters of each process need to be optimized. In a milling machine, some of the important parameters like feed rate, depth of cut, speed, etc, play an important role in achieving the required quality product. To optimize these parameters, the most suitable and widely used method is the Taguchi method. The most significant objective of this research is to obtain effective quality parameters. Experimentation is done on the Jacquard body by varying the milling machine parameters. The experimental results indicate that the minimum surface roughness is obtained for the process parameters feed 0.7 mm per revolution, speed 225 rpm and 1.5 mm depth of cut. This study recommended that more surface finish be obtained by increasing speed, low feed rate, and depth of cut.
