Abstract

In this experiment, effect of tool geometries, material hardness, feed rate, and cutting speed on cutting forces were experimentally investigated. High speed steel (HSS) tool blank with three type of geometries was prepared and mild steel CF1018 and DF2 steel bars were used as workpiece. Effect of tool geometries material hardness and cutting parameters on cutting forces statistical analysis of variance was performance. During the experiments two component of tool of tool force and tool life of cutting tool were measured. This experiment shows that the effect of tool wear was influenced to increase the cutting force. Different of tool geometries were showed the variance was performance on cutting force. Where sharp edge show lower tangential force on CF1018. The contact between lmm radius (nose radius) and workpiece had been small impact on cutting force. But honed radius always high tangential force on CFl 018 remarkably influence to material hardness also cutting force. However material hardness is a one of the factors of increased cutting force and tool life. Therefore, the resulted obtained from the analysis technique indicated that the longer the cutting tools were in contact with the workpiece, the higher the rate of wear. The Taylor's equation derived from the experiment is VT0· 15 = 4.78.
