Identification of Tool Life and Wear Characteristics of HSS Tools Used in Turning of Ck45

Cutting tools can be used when they do not reach tool life criteria and can produce parts with desired surface finish and dimensional accuracy. When the cutting edge of the tool reaches one of the tool life criterion, the tool should be replaced by a new one or sending it for regrinding [1]. During cutting operations, the cutting tool experiences various stresses such as normal, shear and also thermal shocks. These stresses cause wear and breakage of cutting edge. Tool wear is defined as a gradual loss of tool material at contact zones of workpiece and tool material, resulting the cutting tool reaches its life limit [2]. This research is based on ISO3685 and investigates the flank wear patterns of HSS tools during machining of CK45. It also determines the effects of cutting conditions on Taylor tool life equation.
