Abstract
This chapter introduces two nontraditional machining processes: laser machining and electron beam machining. These two machining processes use laser and electron beams as energy sources to introduce thermal energy to remove work material by melting and/or vaporization. The chemical reaction between the photon/electron and workpiece is another material removal mechanism using laser. When performing precision micromachining, it is important to consider the chemical reaction to achieve the accurate dimension and desired surface integrity. Applications of laser and electron beam machining processes are broad, from large-scale cutting to microscale drilling of work materials ranging from hard metals to soft polymers.
