Abstract
Manual finishing is an important die manufacturing process, which decides the surface roughness and form accuracy of a die. However, manual polishing consumes several days to finish a die surface. Therefore, high precision die milling or grinding are required that improve surface roughness, in order to minimize manual operation. In the previous report, ultrasonically diamond grinding experiments were carried out to confirm ultrasonically oscillation effect on the ground surface by face grinding. And mirror surface was obtained. In the present study, we fabricated electroplated diamond grinding tool to reduce tool run–out and improve flexibility of tool selection for ultrasonically assisted grinding. The effects of grinding conditions such as feed rate and radial depth of cut on the surface roughness are presented. A relationship between the surface roughness Rz and grinding time was investigated to evaluate tool life.
