The Influence of Temperature on Cutting Force

Abstract

Cuttime forces at elevated temperature of work material (paraffin) were calculated in various cutting conditions experimented.
In general, the higher the temperature, the lower the cutting force.
Cutting force is affected by two factors; one is the shear strength of work material and the other is the factor related to the cutting mechanism. The former was decreased exceedingly at high temperatur as reported previously (Part 2), and influences of the latter is not so much. Therefore, the decrease of cutting forces is mainly due to low shear stren-gth of work material at high temperature.
