Abstract
The process of traverse dressing using a prismatic diamond rotary dresser was simulated based on a kinematic model, and the effects of dressing conditions on the grinding wheel removal per diamond grit, the actual depth of cut of diamond grit in dressing, and on the rubbed area of the grinding wheel surface in dressing-out were investigated. The prismatic diamond grit of the rotary dresser cuts the grinding wheel surface intermittently so that a residual depth of cut remains on the dressed surface, resulting in grinding wheel removal and an actual depth of cut that are larger than those calculated geometrically on the assumption that the dressed surface is flat. The actual depth of cut of diamond grit for down-cut dressing is greater than that for up-cut dressing when the depth of cut of dresser and the velocity ratio have the same values. The ratio of the rubbed area increases with the circumferential length of the diamond grit and is affected by neither the depth of cut of the dresser nor the velocity ratio.
