A011 Pulsed Laser Milling Integrated Die and Mold Machining : Experimental Analysis of Laser Irradiation Method on Process Performance

DOI Web Site

Description

This paper proposes a novel process to achieve high efficiency die and mold machining technology. The process consists of laser milling for rough process and micro end milling for finishing. In the present paper, reasonable pulsed laser irradiation method is investigated in advance. Some fundamental experiments were carried out to clarify influences of laser irradiation conditions on surface quality and material removal rate in case of hardened die steels for workpiece material. As a result, reasonable laser irradiation conditions including shorter pulse duration and higher peak power irradiation were derived.
