Feasibility study on SiO2f/SiO2 composites processed by diamond tools

Abstract

The thin-wall shell parts manufactured by quartz fiber reinforced ceramic matrix composites have low machining efficiency and bigger cutting force, which can easily lead to broken parts and bad surface roughness not meeting the requirements. To solve these problems and seek feasible cutting tool and process parameters, based on the principles of micro cutting, the feasibility study of SiO2f/SiO2 was carried out by using the developed integral multi-edge PCD tool and electroplated diamond grinding tool. The experimental results show that the integral multi-edge PCD tool, designed based on the micro-edge cutting principle, can achieve a large cutting depth and a large cutting efficiency, but its cutting force is relatively huge. Compared with the integral multi-edge PCD tool, electroplated diamond grinding tool have lower cutting force, better surface quality and lower surface roughness.
