Abstract
A die change method includes providing a press apparatus having a base and a ram, and a first die set including an upper die member and a lower die member. The lower die member is supported on the base and the upper die member is mounted on the ram. The ram is lowered into a closed, home position to mate the upper and lower die members and to perform an operation on a workpiece disposed between the die members. The ram is released from the upper die member. The ram is raised a minimum distance to provide minimal clearance for removing the upper and lower die members from the press. The mated upper and lower die members are moved out of the press with the workpiece held between the upper and lower die members.
