Paper Abstract

A brief review of a laser as a machine tool is given together with drilling mechanism. The effects of the variation of laser machining parameters and materials on the hole geometry are examined for Nimonics 75 work-piece material. A statistical approach known as a factorial design is employed to identify the levels of significance of factors that are most important to hole quality. The variation of focal settings with workpiece thickness are also examined. The results obtained showed that the optimal focal setting becomes smaller than the nominal focal position of the focussing lens for the samples thicker than 0.5 mm, but this is reversed for the samples thinner than 0.5 mm.
