ABSTRACT:
A metal stamping die for a punch press is provided that has a programmable logic microcontroller fixed directly to the die body of the stamping die. The programmable logic microcontroller is encased in epoxy resin to protect it from contaminants and to protect it from vibration which will occur as the punch press operates to stamp metal parts. Sensing devices on the stamping die are electrically connected through passages in the stamping die to the programmable logic microcontroller. An annunciator panel is positioned on the programmable logic microcontroller and has light emitting diodes to indicate the type of malfunction in the die which causes the punch press to stop when a malfunction occurs.
