An Experimental Study and Statistical Analysis of the Effect of Laser Pulse Energy on the Geometric Quality During Laser Precision Machining

摘要: In laser precision machining, process parameters have critical effects on the geometric quality of machined parts. Due to nature interrelated involved, an operator has make a host complex decisions, based trial‐and‐error methods, set control related laser, workpiece material, and motion system. The objective this work is investigate experimentally effect pulse energy parts in terms accuracy, precision, surface quality. Experimental study formation craters thin copper foil with variation energy, geometry topology presented. geometrical were measured statistically analyzed respect incident energy. Statistical analysis including pattern recognition was employed analyze experimental data systematically serve proper selection ach...
