Few studies have been reported on the infiuence of work length on the grinding results in cylindrical traverse grinding in high depth of cut. The present report investigates, in the one pass grinding process for various grinding conditions, the variation in the dimensional accuracy related to grinding force and wheel wear, cylindricity, surface roughness, metal removing ratio and grinding ratio with increased work length as well as stock removal. The main conclusions obtained are as follows : (1) The use of a grinding wheel of the higher grade under the conditions of a higher depth of cut and a higher table speed brings the increasing residual stock removal and the worse finishing accuracy due to the grinding force. (2) When the stock removal exceeds a critical value corresponding to the given grinding condition, a large radial wheel wear appears on the opposite side to the starting position of traverse grinding. (3) The larger wheel wear on the opposite side brings a larger residual depth of cut and makes worse the dimensional accuracy, the cylindricity, the surface roughness, the metal removing ratio and the grinding ratio. (4) The critical stock removal becomes larger for lower depth of cut, that is, lower stock removal rate, and wheel of the higher grade.
