Abstract
AbstractIn this paper, we present the detailed techniques of machined surface errors analysis for laser micromachining of biocompatible polymers. Laser micromachining, with its noncontact characteristics and extensive material selection, is a good fit for microscale biomedical devices manufacturing. Machined surface error of laser micromachining is different from that in conventional machining processes and has not been fully addressed yet. In this paper, we present the formulation and modeling techniques to analyze the sources of machined surface errors and to consider the overlapping effects for laser micromachining. An analytical model is proposed to calculate and predict the machined surface errors considering the overlapping effects in laser micromachining. Experimental results based on laboratory experiments are presented for validation of the proposed analytical modeling techniques. The presented techniques can be used in integrating CAD/CAM systems with laser micromachining of biocompatible polyme...
