Abstract
V-profile groove grinding process of fine ceramics with a formed metal-bond diamond wheel is experimentally investigated, analyzing initial profile of formed wheel, wheel wear, stock removal, grinding force, number of cutting edges on working wheel surface and so on, comparing with those in grinding metals with WA vitrified-bond wheel. Main results obtained are as follows : (1) Initial profile of formed metal-bond diamond wheel is expressed by an isosceles triangle whose top is rounded like that of WA wheel, but the tip radius of diamond wheel is much larger than that of WA wheel. (2) The number of cutting edges on working wheel surface is approximately constant and is not affected by different positions along wheel width and different angles of formed wheel, which is different from that in WA wheel. (3) The ratio of wheel wear to grinding length in steady wear region is decided only by initial cutting depth and is not affected by different positions along wheel width and different angles of formed wheel.
