An experimental method for determining cutting forces

Abstract

The prediction of the force required to cut a material has been one of the central problems of interest in metal cutting. Many theories have been presented, but because of their predictive inaccuracies, they have rendered themselves wholly unacceptable for practical use. In this thesis an empirical method of predicting the forces produced during cutting is developed for SAE 1117, CRS, SAE 4145 HRS and SSE 6150 HRS materials. The same type of empirical method is also presented to predict cutting forces for any type of steel by knowing its ultimate shear strength. This can be used to predict the cutting force and feed force, once, the cutting conditions have been selected and without the necessity of conducting a trial cut
