Abstract
Recently, laser micromachining and micro-fabrication processes have remarkable and diversified applications in the direction to manufacture highly precised and accurate dimensional parts or components which are used in bio as well as technological domains such as biomedical, dental and orthopaedic, aircraft engines, micro-electromechanical systems (MEMS), electronic devices, turbocharger rotor parts and nuclear reactors. The present chapter deals with experimental investigation into micro-turning process using pulsed Nd:YAG laser during machining of aluminium oxide ceramics. A number of experimental schemes were adopted to explore the parametric influences on process characteristics such as surface roughness and depth deviation. Experimental investigation was also carried out to improve the dimensional accuracy and surface characteristics of laser micro-turned components using laser defocusing technique.
