A micro cutting has been performed on hard nickel alloy using a short-pulsed laser machining process. The input process parameters such as laser power, laser scan speed and laser beam frequency are varied to study the quality of micro profile. Scanning electron microscopy is used to measure the dimensional quality of the micro profile. At slow scan speed (50 mm/sec) the profile breadth found to be close 290–330 μm. at maximum scan speed (100 m/sec) the breadth dimension is varying. Similarly, the breadth of the profile found variant at all three scan speeds in line with the laser power and laser power frequency. Statistical technique is used to study the influence of input process parameter. In order to find the optimal process, the adam – gene multi varying population based evolutional search algorithm is adopted. The minimum laser power with average laser scan speed and frequency has yielded with best process condition for proposed problem.
