Press apparatus, striker control modular tool apparatus and programmable method for punching apertures into a workpiece

摘要

Method and apparatus for punching apertures into a workpiece. A press apparatus includes an inputting device, that enables a user of the press apparatus to input working pattern data representing the workpiece, and a display device, that displays a working pattern of the workpiece based on the inputted working pattern data. A tool selecting device selects a plurality of tools required for working the workpiece in accordance with the working pattern data. A calculator calculates a transferring pitch of the workpiece in order for parts of the workpiece to be sequentially arranged in predetermined positions in a feeding direction of the press apparatus with respect to the plurality of tools selected by the tool selecting device. In this regard, the calculator also determines which tool is to be operated in association with the transferring pitch. The press includes a controller that controls the transferring pitch calculated by the calculator.
