Abstract
A highly productive completely automatic tracing shaper machine tool performs sequential operations without manual attention permitting a single operator to simultaneously run several machines without being exposed to the shaper heads of the machine. The tracing shaper machine tool has a track mounted vacuum feed table or chuck clamping thereon a template or pattern and the wood workpiece to be shaped. The table is manually positioned on the track to accommodate a wide range of workpiece sizes and this initially positioned table or chuck with the stacked template and workpiece vacuum clamped thereon is automatically biased toward a selectable speed driven upright shaper tool carrying spindle with a rotatable follower bearing surrounding the spindle receiving the periphery of the template thereagainst at a constant pressure. The feed table or chuck is rotated to provide a desired feed rate of the workpiece to the shaper tool, and this rotation continues somewhat beyond a 360.degree. turn, whereupon the biasing means is reversed and the chuck retracted to its starting position on the track. A hold-down wheel is automatically pressed against the workpiece adjacent the peripheral edge being cut by the shaper tool to prevent jumping of the workpiece from the cutting action. The machine has an air logic system sequentially controlling the operating steps.
