Abstract

The present work concerned an experimental study on machining parameter in a milling operation for carbon fib er reinforced polymer (CFRP) to compare the surface roughness. The main objective of the study was to study the effect of machining parameter such a cutting speed, feed rate and depth of cut on the surface roughness of CFRP. The objective was to determine which of the following machining parameters produces the best surface finish and to compare the results obtained to regulate the best effect of machining parameters on the surface finish using Taguchi method. In order to determine the best cutting speed or the material, there were other cutting parameters needed to be constant, such as feed rate ano depth of cut. In machining operation, the quality of surface finish is an important requirement for many workpieces. Thus, the choice of machining parameters was very important for controlling the required surface quality. The-focus on determines which of the following machining parameters produces the best surface finish and also to compare the results obtained to regulate the best effect of machining parameters on the surface finish using Taguchi's method. Among the considered parameters, speed has the greatest impact on the workpiece's surface roughness. The optimum speed obtained using the Taguchi approach in this experiment is 5000 rpm. Similarly, the feed and depth of cut figures were 800 mm/min and 0.3 mm, respectively
