Research on Design Theory of Micro-cutting Tool of Monocrystalline Diamond

As the development of modern manufacturing, micro-miniature products have attracted a lot of attention due to their reduction of materials and energy consuming and high utilization of space. The micro monocrystalline diamond (MCD) cutting tool, which can cut parts into three-dimensional micro-parts with super smooth surface and super precision dimension accuracy, is a key issue to ultra-precision machining of micro-parts. In the research, the design principle of micro MCD cutters and the mechanical analysis are studied based on the introduction of the application and features of micro-milling cutting tool of MCD. Then, experiments are made to show the feasibility of fabricating MCD micro-cutting tool by grinding with diamond wheel.
