碩士 === 國立虎尾科技大學 === 光電與材料科技研究所 === 97 === The opto-electronics industry has been developed rapidly in recent years. In order to enhance image quality and meet the industry requirements for light weight, thinness, compactness and low cost, aspheric surface micro-lens has been widely used. For example, mobile cameras and blu-ray pick-up lens are both developed towards having large slope angles. As for quality properties such as form accuracy and surface roughness, the higher quality requirements of the product, the more restrict requirements for the ultra-precision machine technology widely used today. Accordingly, this thesis aims to investigate the factors effecting the form accuracy and surface roughness of large slope angle molds so as to enhance the surface quality of workpiece. In this thesis, Taguchi method is applied to investigate the processing parameters for the ultra-precision machine technology to optimize surface quality. Experiments are done by using single-point diamond tools to cutting electroless- nickel molds. The processing parameters involved are insert radius, feeding speed, spindle speed, and depth of cut. The effects of said different processing parameters on form accuracy and surface roughness are examined through orthogonal array, signal-to-noise ratio and analysis of variance (ANOVA). The experiment results demonstrates how to use Taguchi method parameter design for optimizing machining performance that can effectively enhance form accuracy and reduce surface roughness.
