Abstract: In micromachining the achievable range of material removal depth is the range of 1 x 10-6 m to 10-3 m. The least count in a normal milling machine is 0.01mm which is greater than 10-3 microns. Normally micro milling is done on specific milling machine which can achieve such micron level of material removal and they involve very high cost. This report is on the experimental procedure done for micro end milling on normal milling machine. During the machining various parameters like speed, feed and depth of cut were varied and surface roughness obtained for each value is noted and an optimum combination value for above is proposed.
