Design and manufacturing of ultra-hard micro-milling tool

Abstract

Based on the study of existing typical micro-milling tools and the actual demand for micro-milling tools, the P³ design principle and design flow for ultra-hard micro-milling tool were introduced to give basic guidance for the optimization of micro-milling tools. Then, according to the P₃ design flow, the manufacturing process of polycrystalline diamond (PCD) micro-milling tool was proposed, and the PCD micro-milling tool with diameter of 0.5 mm was developed. Finally, the micro-milling test on the slot was carried out to study the milling performance of PCD micro-milling tool.
