Abstract
Drilling of various materials by electron and laser beams has been studied with the purpose of comparing the two kinds of processing. The minimum spot obtainable with the electron beam is smaller than that with the laser beam. Hence a smaller hole can be perforated by the electron beam. But, in power efficiency, the laser beam is superior to the electron beam. When the two beams are allowed to impinge upon a metal work-piece, the surface power density of both beams is nearly of the same order, but a higher volume power density can be expected with the laser beam. These results are explained by the characteristics of the two beams.Keywords
