Abstract
A feed mechanism for feeding a work piece to a tool includes a control system for monitoring feed operation. The feed mechanism includes at least one vise movable with respect to a support structure to advance a work piece. The amount of movement permitted the movable vise is adjustable by a coarse and fine adjustment system employing simplified structure for setting the stop defining the movable vise start feed position. The movable vise is driven by a mechanism interconnected to the movable vise by a pin and slot arrangement which permits the vise to accommodate warped work pieces. Preferably, the feed mechanism includes a second fixed vise, one jaw of which is adjustable to permit parallel alignment of vise jaws forming the fixed vise. The control system employs a manifold having a mounting surface for interconnecting various ones of the devices operating the feed at a central, programmable location.
