Abstract

Material selection is determined by the purpose of the product. Material selection is critical when considering the quality of the final products and waste produced during CNC milling machining. Based on previous study, multiple ductile and brittle material were being tested to undergo high speed machining to identify which material category has better surface roughness. The goal of this project is to evaluate machining time and surface roughness for aluminum and mild steel with varying spindle speeds. This study focuses on the comparison of aluminum and mild steel for CNC milling operations utilizing CAD/CAM programming. Mastercam software is used to design the 2D and 3D of the sample block, and simulation is used to get a preview of how the toolpath of the machining will look and to gain the expected time for the machining time of each parameter, which are 1000rpm, 1200rpm, 1400rpm, 1600rpm, and 1800rpm with a constant feed rate of 500mm/rev and a constant depth of cut of 0.5mm. As a result, when both aluminium and mild steel are machined using Computer Numerical Control (CNC), it is proven that aluminium have better surface roughness and time saving then mild steel
