Experimental study of the heat affected zone (HAZ) and surface roughness on laser beam cutting (LBC) on acrylic sheet

Nowadays, laser beam is a practical and versatile tool for processing range of alloys, glasses, ceramics, composites, polymers and metal in manufacturing industries. Laser beam cutting (LBC) is achieved by the radiation emitted by a focused beam of coherent light with a assistance of a high pressure...
