Abstract
A radial cut profile is achieved while advancing a workpiece at a substantially constant rate in a direction towards a cutting blade by moving the workpiece vertically relative to the blade in synchronization with the oscillation of the workpiece. The vertical movement is provided by a linkage including two links pivotally connected to each other. The other end of one link is pivotally connected to the feed mechanism. The other end of the other link is fixed relative to the oscillating workpiece.
