Abstract

Quality of surface roughness is one of the challenges in the industry to produce high quality products. Cutting parameters and type of cutting tools are the factors that affect the quality of surface roughness. The purpose of this study is to examine the influences of different types of cutting tools coating and cutting parameters on the surface roughness. The cutting tools used are (TiN, TiCN and TiAlN). Taguchi method is used with three factors and three levels which is spindle speed (500. 1000, 1500) rpm, feed rate (500, 800, 1000) mm/min and diameter tool size (8, 10, 12) mm. The experimental results showed that, with larger diameter tool size the value of surface roughness will decrease. Same goes to spindle speed. When increasing spindle speed from (500-1500) rpm, the value of surface roughness also decreases. Different results surface roughness in feed rate, lower feed rate will produce better surface roughness. With suitable cutting parameters, TiAlN showed in decreasing surface roughness compare to the other two types of cutting tools. Confirmation test had verified that Taguchi design was successful in investigating the effect type of cutting tool coating on the surface roughness.
