Abstract

A study of the wear behaviour of the tools operating under accelerated cutting conditions would be of practical value. Experimentally it has been found that tool flank wear during facing follows an exponential law (VB = a ebt) instead of three stage flank wear normally observed during conventional turning. The effect of spindle speed and feed rate on flank wear was analysed and found that wear increases as the value of these parameters is raised. Flank wear also increases with increase in shear strain acceleration. A response surface equation has been suggested that gives the effect of the parameters and their interactions on the tool flank wear.
