To determine

Estimate the cutting temperature for the conditions of Problem 21.65 if the following properties apply.

	Workpiece material
	Aluminium	Steel
Chip energy $\mu \left(\frac{N-\text{mm}}{{\text{mm}}^2}\right)$	1320	2740
Thermal diffusivity $k\left({\text{mm}}^2/s\right)$	97	14
Volumetric specific heat, ${\rho }_c,N/{\text{mm}}^2{}^{\circ }\text{C}$	2.6	3.3
