Abstract

This project represents the investigation of the effect of rake angle variation on the endmill wear, cutting force and surface finish. Conventional milling machine is being used in this analysis. The main purpose of this project is to study the effect of end mill rake angle variation to rate of wear of end mill and surface finish of the machined workpiece and also to understand the impact of endmill rake angle variation to the cutting force during milling process. The workpiece use in this experiment is limit on mild steel only. The workpieces is machined first before machining with dynamometer that clamps with workpiece to get cutting forces data. This experiment was using 3 different rake angles of endmill cutting tool that machined using CNC Tool Grinding. Surface roughness and tool wear also the finding for this experiment. The parameter will be in fixed setting such as depth of cut, spindle speed and feed rate. Then the data will be analysis using Microsoft Office Excel to find which cutting tool is suitable with the industry usage. Finally, rake angle with 10⁰ is the best endmill cutting tool in conventional milling machine through the experiment.
