An active work rest with pneumatic bellows has been developed for cancelling out the grinding forces and suppressing the deflections of the workpiece together with its supporting system. Although response of the active rest is limited to a lower frequency range, it has been found adequately effective in improving the form accuracy of the ground component. It has been ascertained by grinding experiments that by using the active rest, the residual normal and tangential force components acting on the workpiece and its supports can be reduced to within ±5 N. The grinding time constant is fairly less than that with conventional setup. Cylindricity and/or roundness are considerably improved in both traverse grinding of a slender workpiece and plunge cut grinding of a workpiece with directional stiffness due to non-circular cross-sectional rod attached to both ends.
