ABSTRACT:
A backgage (22) for use in conjunction with a press brake (10), includes an arm (24) movable in three axial directions (R, X, Z) by a drive (26). A gage block (54) is supported on the arm and includes a gage finger assembly (72) including a movable finger (76). A projecting member (94) engages a recess (100) in the finger to releasably latch the finger in a first position. Excessive force encountered by the finger during a collision with an obstruction unlatches the finger and enables it to move to avoid damage.
