  • a sensing device positioned between the workpiece and tool and having a passive contact sensing element rigidly secured to an active sensing element at a known distance such that the passive contact sensing element mechanically contacts the workpiece;

    means for providing relative movement of the workpiece and the sensing device toward the tool and along a main feed axis until the active sensing element detects the position of the tool; and

    control means responsive to the active sensing element for determining the relative distance between the tool and the workpiece based on the known distance between the active and passive contact sensing elements.
