- Abstract
- Although nanosecond pulsed laser drilling and milling are rapid and non-wear processes in
micromachining, the quality cannot meet the precision standard due to the recast layer and heat
affected zone. On the other hand, electrical discharge machining (EDM) is a well-known high
precision machining process in micro scale; however, the low material removal rate (MRR) and
tool wear remain as drawbacks. In this paper, hybrid process of laser beam machining (LBM)
using nanosecond pulsed laser and micro EDM was studied for micro drilling and milling. While
the quality of the micro structure fabricated by this hybrid process remains as high as direct EDM,
the machining time and tool wear can be reduced. In addition, variable depth of layer was
introduced as an effective method improving efficiency of hybrid milling.
