A Method to Determine Cutting Force Coefficients in Turing Using Mechanistic Approach

Abstract

During performing turning operation, cutting force plays a significant role in metal cutting process affecting tool-workpiece deflection, machine tool vibration and eventually part quality. The present research work aims to develop a mechanistic cutting force model that will be used in development of tool-workpiece flexible system of thin-wall machining. It also concentrates to study the mechanistic constants used in the force model in case of turning operation. The proposed model can be used for the reliable and accurate estimation of the cutting forces establishing relationship of various force components (cutting force and feed force) with uncut chip thickness. The accurate estimation of cutting force is required to improve thin-walled part accuracy by controlling the tool-workpiece deflection induced surface errors and tool-workpiece vibration.
