摘要：Ceramic materials are widely used industrial products because of their excellent properties such as resistance to wear and high temperature. However, the high strength of sintered ceramics posts difficulty in micro machining ceramic materials to desired shapes, especially in processing 3D micro-features which require high precision and high quality. In this paper, the study includes the influence of machining gap and tool axial wear on the dimensional accuracy of the 3D structure, the effect of coolant, and the layer thickness and ceramic compact strength on the machining quality of the micro-structure. Based on the analysis of extensive experimental results, the best machining results are achieved when the ceramic green strength is set at 9MPa within the range of experimental conditions in this study to generate 3D micro-features.
