Abstract
Additive forging technology is an innovative method for manufacturing heavy forgings by using multi-layer hot-compression bonding. To achieve better bonding performance, the surface of the metal substrate needs to be ground and cleaned before hot-compression bonding. However, the process is less automated in factory production which tremendously hinders the increase of productivity. This paper presents an automatic grinding scheme and the experimental device were designed to verify the feasibility of the scheme. The effects of contact pressure, spindle speed and feed speed on the grinding effect of 316H stainless steel were studied. The results show that the best grinding effect can be obtained when the contact pressure is 25 N, the spindle speed is 8000 rpm, and the feed rate is 30 mm/s, which can significantly improve the product quality and production efficiency.
