Feasibility of Laser Induced Plasma Micro-machining (LIP-MM)
Abstract
The paper offers evidence on the feasibility of a
newly proposed micro-machining process, which is motivated by the need
to overcome the various limitations associated with μ-EDM and
conventional ultra-short laser micro-machining processes. The
limitations in μ-EDM and laser micro-machining processes are mainly due
to the requirement of a conductive electrode and workpiece, electrode
wear and compensation strategies, and complex process control mechanisms
respectively. The new process uses a laser beam to generate plasma in a
dielectric near the workpiece surface whose explosive expansion results
in material removal by mechanisms similar to those that occur in
μ-EDM.
