Abstract
Tool Wear is one of the important factors affecting production optimization. The complex stochastic nature of tool wear is one of the obstacles in achieving manufacturing automation. This paper experimentally validates the extended Taylor's Tool Life equation for single point turning tools made from High Speed Steel (M-35) material. A three level full factorial design was adopted for investigating the effect of three parameters viz. cutting speed,feed rate and depth of cut on ToolLife. Experiments were run in a range of parameters, according to a 3 factorial design. The tool geometry was kept same for all the 27 tools made of HSS (M-35) used during experimentation. The predicted and measured results of Tool life in minutes were tabulated. The trends of differentparameters on Tool Life have been graphically presented. The results show a good relationship between the Calculated and Measured values of Tool Life thus validating the extended Taylor's ToolLife equationfor our set of experiments.
