Parametric Optimization of Laser Beam Micro-Grooving of Hydroxyapatite

摘要

Hydroxyapatite is the most widely employed biomaterial for the reconstruction and repair of bone tissue defects. Besides, it is acknowledged that generating a three-dimensional micro-grooving on hydroxyapatite is a challenging task. Hence, this paper analyses the experimental results obtained after performing micro-grooving operation on bioceramics (hydroxyapatite) through Nd:YAG laser beam machine in order to derive optimal parametric settings for the said machining operation. Initially, it is observed from the machining responses obtained after the conduction of experiments that there is a group of process parameters which meet the challenges of machining hydroxyapatite. Single-objective optimization was performed to determine the optimum level of these process parameters. The setting of machining parameters has been determined by using L_9 orthogonal array.
