Abstract

In laser beam micro machining process, the quality of the micro milled component mainly depends on appropriate selection of process parameters. In laser milling technology, the material removal is done by a laser beam through the mechanism of layer by layer ablation. The process is affected by the laser characteristics and the properties of the work material but is mostly influenced by their interaction. The selection of the laser and its parameters significantly affects surface roughness as well as the material removal rate(MRR) of the micropart. In present research, an attempt has been done to study the effect of laser process parameters on the quality of the features obtained by laser machining. In Fiber laser micro milling operation on Inconel 718, scanning speed, frequency, power have most significant effect on all responses.
