-### Aim of the experiment
+### To quantify the stock removal rate from basic concept of bulk boiling for metals using Lazeranko's model
+
+### Objective
+1. To estimate the effect of pulse energy and pulse width on crater depth, crater volume assuming bulk boiling using Lazeranko's model
+2. To understand the phenomenon of over cut, taper and surface finish as a result of variation in pulse energy
