Abstract
A typical spectacle lens-polishing operation was simulated in the laboratory. Forearm flexor, smoothed-rectified EMG signals were used to estimate pinching forces used in the operation. Levels of forces produced were very large, near maximum, reaching values of up to 108 N. Largest forces were obtained at the neutral wrist position. Varying various conditions of the task, indicated that using a straight arm, subjectively low pressure and a zig-zag polishing method significantly reduced the pinching force levels. In addition, wetting the lens and providing visual feedback to the subject also tended to reduce pinching force levels.
