Claim 17:
18. A workpiece-contacting apparatus comprising:
a die including a workpiece-contacting surface;
a punch coaxially aligned with the die;
a primary actuator operably moving the punch from a retracted position to a fully advanced position, the primary actuator including a fluid-powered piston; and
a linearly moveable slide comprising at least one of:
(a) a first spacer extending from the slide a first height, and at least a second spacer extending from the slide a second height, the first height being greater than the second height, the spacers being laterally spaced away from each other such that only one of the spacers is aligned with the punch when the punch is advanced; or
(b) a first portion of a tapered wedge extending from the slide with a first height and at least a second portion of the tapered wedge extending from the slide with a second height, the first height being greater than the second height; and

a secondary actuator automatically moving the slide, along a plane between the primary actuator and the punch, to change a distance between the fully advanced position of the punch and the workpiece-contacting surface of the die.
