In this paper, the curvature of 304 stainless steel thin plate in one pass grinding using WA, CBN and diamond wheels was investigated. And then the result was compared with carbon steel. The influences of grinding direction(up-cut, down-cut) and repetition of grinding pass were also pursued by considering plastically deformed layer. Main conclusions are as follows : (1) In grinding 304 stainless steel plate, WA wheel followed by CBN wheel produced largest concave curvature but diamond wheel causes a little convex curvature. The curvature in grinding 304 stainless steel plate is much larger than carbon steel. The influence of grinding condition, such as depth of cut, wheel speed, and work speed on curvature is generally similar in grinding carbon steel plate. (2) Up-cut grinding causes the larger convex curvature and higher compressive residual stress than down-cut grinding. The plastically deformed layer in up-cut grinding is larger than down-cut grinding in case of carbon steel. (3) As grinding pass is increased, the convex curvature becomes smaller as far as 304 stainless steel is concerned, but the curvature is almost constant in carbon steel plate.
