: In dry machining, the tool-chip interface temperature is a critical factor affecting the engineering performance of WC–Co tools. As the temperature variation of the cutting tool in
dry machining is similar to that in annealing process. How would you investigate the effect of
tool-chip interface temperature on the mechanical properties of cutting tool materials in dry
machining can be studied by means of heat treatment process (annealing)? What would be the
effect of annealing temperature and holding time on the mechanical properties of the WC–Co
materials.
