Abstracts: In this experiment, effect of tool geometries, material hardness, feed rate and cutting speed on cutting forces were experimentally investigated. High speed steel tool blank with different geometries was prepared and gray cast piston was used as work piece. 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 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 gray cast iron. The contact between 1 mm nose radius and work piece had been small impact on cutting force. However material hardness one of the factors of increased cutting force and tool life therefore the result obtain from the analysis technique indicated that the longer the cutting tools were in contact with the work piece the higher rate wear.
