Laser Induced Plasma Micromachining

Lipmm can reduce machining time up to tenfold and can overcome the limitations of other conventional micromachining processes. The new process termed laser induced plasma micro machining 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 m edm.

Laser induced plasma micromachining lipmm is a novel tool less process that has the potential to achieve high material removal rates on materials such as aluminum transparent ceramics silicon wafers and polymers. Laser induced plasma micromachining lipmm process is an effective approach to create micro features with high aspect ratio and reduced heat affected zone. However the throughput of this process is limited by the low scanning speed and low frequency used in the conventional underwater condition due to the disturbance of water layer. Laser induced plasma micromachining lipmm using a 10 ps laser was applied to create micro channels on the surface of al 2 o 3 tic ceramic. The thickness of the nozzle tip is about 500 mm to 2 mm and the orifice is about 25 to 500 mm. Laser induced plasma micromachining lipmm is a novel tool less micromachining process which offers machining characteristics superior to conventional laser ablation such as multi material capability higher machined depth and better wall geometries. Micro channels were firstly created by direct laser ablation and lipmm to comparatively assess the machining ability of two processes. Laser induced plasma micromachining lipmm has emerged as a promising alternative to direct laser ablation for micromachining and microtexturing which offers superior machining characteristics while preserving the resolution accuracy and tool less nature of laser ablation.

An axisymmetric model combining the effects of cascade multiphoton ionization and recombination and diffusion losses was developed to simulate the spatial and temporal plasma. This work investigates the influence of pulse energy on machining characteristics using a 10 ps laser during laser induced plasma micromachining lipmm process.
