Temperature calculation in cutting zones

This paper presents methods for refining the calculation of cutting temperatures. The heat flow densities and temperatures in the chip forming area, the accumulation zone and the area of the plastic contact between chip and tool affect the cutting temperature considerably. The new method takes the heat distribution for moving sources into account. The temperature in the contact between the flank face and the workpiece is calculated considering how friction and the accumulation zone affect the cutting temperature in the tertiary cutting zone. The methods incorporate material softening during temperature increase. The models are verified by experimental analyses. (C) 2018 Published by Elsevier Ltd on behalf of CIRP.
