Cutting Force Evaluation Based On Total Energy Consumption

This paper presents a methodology for practical estimation of the cutting force and cutting power. Providing a complete list of mathematical expressions needed for the calculation, the paper demonstrates their utility for turning operation of two work materials: AISI bearing steel E52100 and aerospace aluminum alloy 2024 T6. The calculated cutting forces are in good agreement with the experimental results. Energy partition in the cutting system and relative impact of the parameters of the machining regime are discussed. For the first time, a simple practical method is available for the calculation of the total cutting power and the cutting force.
