Abstract

The aim of this research is to obtain the optimal parameters for machining FC300 cast iron interns of surface roughness and surface texture. FC300 is a material that frequently used in die industry. The parameters that will be evaluated are based on the 6000 – 9000 rpm spindle speed, 4 – 7 m/min feed rate and with constant depth of cut 0.01mm. In this research, the machining conducted by using CNC milling machine under dry condition and the cutting tool that will be used is uncoated carbide ball end mill with diameter 32mm. The performance of surface integrity for FC300 cast iron will be measure by surface roughness machine and surface profile using Scanning Electron Microscope (SEM). Response Surface Methodology (RSM) was used to evaluate the optimum cutting parameter in order to obtain a better surface finish. This research will provide useful information about the suitable cutting parameter to machining FC300 cast iron efficiently.
