Abstract
The elimination process of the eccentricity of a cylindrical workpiece as a basic model of the shape error was experimentally analyzed. The results may be summarized as follows : In the one pass traverse grinding, a limit residual shape error is in existence. The limit value increases as initial shape error grows larger. When total setting depth of wheel is a constant, the residual shape error is reduced in size by decreasing the setting depth per traverse, and by increasing the number of traverse. In order to eliminate the effect of initial shape error by the spark-out grinding, it is necessary to establish the setting depth of wheel over the sum of initial shape error in size and a limit residual stock removal.
