Patent ID: 8201432

Claim:
A plate workpiece processing machine, comprising: a workpiece support; a tool punch holder configured to hold a tool punch; a tool die holder configured to hold a tool die; a tool drive operable to move at least one of the tool punch holder and the tool die holder to reduce a separation between the tool punch holder and the tool die holder along a stroke axis for processing of a plate-like workpiece supported on the workpiece support; a plurality of tool punches selectively mountable on the tool punch holder, each of the tool punches having a tool punch shank and a tool punch head adjoining the tool punch shank, the tool punch shank of each tool punch being configured to be secured to the tool punch holder and the tool punch head of each tool punch being radially enlarged relative to the tool punch shank and being arranged towards the workpiece when the tool punch is mounted on the tool punch holder; and a plurality of tool dies selectively mountable on the tool die holder, each of the tool dies having a tool die shank and a tool die head adjoining the tool die shank, the tool die shank of each tool die being configured to be secured to the tool die holder and the tool die head of each tool die being radially enlarged relative to the tool die shank and being arranged towards the workpiece when the tool die is mounted on the tool die holder, wherein the tool punch heads of at least some of the tool punches have differing heights along the stroke axis as mounted on the tool punch holder, and the tool die heads of at least some of the tool dies have differing heights along the stroke axis as mounted on the tool die holder, and wherein the tool drive is configured to position the tool punch holder with respect to the stroke axis based on the tool punch head height of the tool punch of the plurality of tool punches having differing heights along the stroke axis which is secured to the tool punch holder, and to position the tool die holder with respect to the stroke axis based on the tool die head height of the tool die of the plurality of tool dies having differing heights along the stroke axis which is secured to the tool die holder.
