Preliminary experimental analysis of the surface topography formation during laser polishing H13 tooling steel using statistical characteristics of the surface amplitude distribution	2020-12-31		.txt	text/plain	3441	188	40	To complement that, laser polishing (LP) is one of the advanced manufacturing surface finishing techniques that has been recently developed and successfully employed for improving surface quality without deteriorating the overall structural form through surface smoothing by melting and redistributing a thin layer of molten material. To exemplify the effective application of statistical amplitude distribution characteristics, LP experiments were conducted with two different laser powers (25 W and 100 W) on flat and ground initial surfaces and resulting surface topographies were measured. The current study plans to demonstrate that the resulting quality of the LP surface is affected by two interrelated thermodynamic processes induced by the moving laser source, namely melting, redistribution and solidification of both solid body and surface topography. The effect of laser power on surface topography formation and its thermodynamic and statistical components was studied by comparing initial and LP longitudinal Y-Y cross-sections hini(x) and hLP(x) of ground and flat samples with different LP powers (25 W and 100 W).	./cache/cord-103877-03b1t37r.txt	./txt/cord-103877-03b1t37r.txt
