Abstract
Grinding process of V-profile groove with a formed wheel is experimentally investigated, analyzing initial profile of formed wheel, wheel wear, stock removal, number of cutting edges on working wheel surface, bonding strength of a cutting edge and so on. Main results obtained in this paper are as follows : (1) Initial profile of formed wheel is different from ideal one at tip zone of V-profile. (2) The number of cutting edges increases with increasing depth from wheel surface, increasing distance from the center of wheel width and larger formed angle of wheel. (3) The bonding strength of a cutting edge increases with an increase of formed angle of wheel. (4) The ratio of wheel wear to grinding length is decided only by real cutting depth and is not affected by grinding length and different positions along wheel width. (5) The generated groove angle as compared with formed angle of wheel becomes larger with an increase of grinding length because of wheel wear.
