Abstract

Surface roughness of tool steel AISI D2 is studied to investigate the effect of cutting parameters (cutting speed, feed rate and coating) on surface roughness at various machining parameters. Coated cerbide tools (KC 9125) and uncoated carbide tools (K 313) were used in turning tool steel AISI D2 bar with hardness of 267 HV. Machining tests were performed in dry cutting condition at various cutting speeds and feed rates while the depth of cut was kept constant, Taguchi's design of experiment with standard orthogonal array L12 was cmployed to accommodate the machining prrameters of various cutting speeds and feed rates. Coating cutting speed and feed rate inlluenced the surface roughness values but the main factor thst grve a significant effect on the surface roughness is the feed rate, for both types of cutting tools. The high cutting speed and low feed rate produced a low surface roughness value. The lowest surface roughness value for uncoated and coated carbide tools were recorded at a combination of the cutting speed of 250 m/min and the feed rate of 0.05 rpm/put Generally, coated carbide toots with low feed rate performed better than uncoated carbide tools.
