Abstract

This project is carried out with the purpose to find or get the relationship between machining process and the result of surface finish. The scope of this study chose a Computer Numerical Control (CNC) Lathe Machine operation for machining process and machinability such as spindle speed and feed rate for cutting parameters. The material will be used are copper, aluminum and mild steel. The cutting tool using for this study is a Tungsten Carbide. After machining process, fmd the surface roughness depends on characteristic of surface finish. The surface roughness will be measure and the result obtained will be analysis on it. The analysis of the surface roughness showed the relationship between machinability like spindle speed affected the quality of roughness surface from Ra and Rmax versus spindle speed graph plotted. The result of the experiment showed that at a particular spindle speed produced the different surface finish.
