The purpose of the paper is to obtain the most efficient infeed curve of wheel spindle stock in plunge grinding. In accordance with this infeed curve, workpiece can be ground at the shortest cycle which is consistent with required quality and accuracy of product. For example, the cycle time can be reduced about thirty-five per cent compared with the grinding at a fixed speed. The quality and accuracy are evaluated by size, roundness, surface roughness and affected layer. The effect of grindability, which changes with stock removal, is also investigated on the infeed curve.
