“…This work also deals with the removal of these abnormalities such as the burr, coolant pressure, feed rate etc. The sequence of the operations in VMC for crankshaft has been listed below Bhargab Kalita et al [1] reviewed the experimental investigation and optimization of process parameters in drilling mild steel with HSS drill bit using Taguchi Method Methodology to obtain minimum surface roughness. It has been observed that the minimum surface roughness of a machined workpiece is influenced by several process Impact Factor (JCC): 7.6197 SCOPUS Indexed Journal NAAS Rating: 3.11 parameters such as spindle speed, feed rate, cutting fluid, drill tool diameter etc.…”
