摘要： A master die set and unit die system for use with a punch press, the master die set adapted to receive, align, clamp and release unit dies of standard dimensions so that unit dies may be quickly changed in the master die set while the master die set is operably installed in a punch press. The upper shoe of the master die set includes a sliding dovetail to align and clamp a punch holder plate of standard dimensions, the sliding dovetail operated by a single clamping screw. The opposed bottom shoe of the master die set includes a recessed pocket and clamps to align and clamp a unit die blank of standard dimensions in registry with the punch holder plate. The master die set is attached to the punch press by bearings so that the entire die set can rotate with respect to the punch press to cut saw teeth having the same tooth length, but different gullet depths, with the same die. Gage blocks are provided with the saw tooth cutting die to determine the amount of rotation necessary to cut saw teeth having a particular gullet depth.
