摘要：

The CVD diamond micro-grinding tool highly promising for micro-scale high accuracy machining. To improve the lubrication and chip removal performance in the grinding zone, a kind of micro-structured CVD diamond micro-grinding tool. Firstly, the commercial FEM software was adopted to analyze the effects of micro-structure parameters on the deformation and stress distribution of the micro-grinding tool. And then, the coolant flow fields in the grinding zone included the macro flow field, micro flow field and chip evacuation were simulated. The effects of micro-structure parameters and grinding parameters on the flow field performance and the transport capacity of chips were obtained, which provides a basis for the surface micro-structure design and optimization of the CVD diamond micro-grinding tools.
