Tool components and related machines and methods

A tool die for processing of plate-like workpieces, the tool die comprising:

• an end face adjoined by a tool region provided for regrinding;
• and
• at least one identification mark located on the tool die to indicate an amount of shortening of the tool region as a result of regrinding,
• wherein the tool region comprises a frustoconical inclined portion formed around the end face,
• wherein the identification mark extends circumferentially along an outer surface of the frustoconical inclined portion in a substantially helical manner,
• wherein the tool die defines a smooth bore extending from the end face, the smooth bore being configured to receive a punching tool for processing a plate-like workpiece supported above the end face of the tool die, and
• wherein the identification mark travels from the end face in an axial direction that is perpendicular to the end face to a maximum axial length of the identification mark, wherein the identification mark terminates at a single revolution around the end face at the maximum axial length, and wherein the maximum axial length corresponds to a maximum regrinding length of 1 mm from an initial axial position of the end face in a new, non-ground state of the tool die.
