Abstract :
Laser processing is an important manufacturing technology in machining difficult-to-cut materials. A sound generates when a laser processing is carried out, and the intensity of a sound changes according to processing conditions. The goal of the research is to construct a laser processing system for the manufacture of free form surface. In order to achieve this goal, this study aims to clarify the relationship between the strength of laser processing sound and groove cross-sectional area per pulse when Q-switched YAG laser beam was applied for laser grooving
