Abstract
Alternative tool wear compensation modules employing drawbar actuated tool position adjustment or electrically activated solid-state prime mover adjustment including means for physically sensing and verifying the extent of adjustment without awaiting the gaging of successive work piece dimensions following compensation adjustment. In one embodiment, a piezoelectric stack is employed with a flexure unit mounted tool to produce adjustment deflection through controlled voltage applied to the piezoelectric stack.
