Abstract: In present scenario it is necessary to optimize the cutting strategies for forging die manufacturing on CNC milling machines. Manufacturing of dies has been presenting greater requirements of geometrical accuracy, dimensional precision and surface quality as well as decrease in costs and manufacturing times. In this study, effects of the cutting parameters on geometrical error have been examined on a representative die cavity profile. Design of Experiment Method has been employed to find out the effects of the cutting parameters on the geometrical accuracy of the manufactured cavity profile. Prediction formula is derived to estimate the geometrical error value in terms of the values of the cutting parameters. Validity of the prediction formula has been tested by conducting verification experiments for the representative die geometry and die cavity geometry of a forging part used in industry.
