Abstract (en)
[origin: EP2762245A1] The method involves monitoring the metal sheet material (110) during reforming process in press-bonded material deforming tool (200), by a sensor (400). The separation of metal sheet material at defined location is performed by separation device of press-bonded material deforming tool, if the critical state generated due to increased flow of material in reforming process is recognized by sensor. An independent claim is included for a press-bonded material deforming tool.
