Metal Stamping terms and Glossary
Die shut height, Press shut height, feed height

It is self evident that, if a tool or Die is to be run in a given press machine, the tool much be designed to in accordance with the various press dimensions with pertain to the die to press relationship. These dimensions are normally taken from the press specification chart. The required dimensions may be ascertained by actually measuring the specific press in which the die is to be run.
In general, some metal stamping terms and glossary such as Die shut height, Press shut height, feed height etc. have to be understood.

 

Die Shut Height .
By definition, the shut height of the press is the distance from the top surface of the upper shoe to the lower surface of the lower shoe when the tool is in the lowest operation position. When the tool is been operated in the press, the press shut height and the die shut height coincide exactly. With cutting die, the die shut height normally becomes slightly lower each time after the die is sharpened.

Press shut height.
Press shut height is always means the dimension from the table surface to the press's ram when the press is at bottom dead center ( BDC) position, maximum press shut height means the press adjustment is at it highest stroke down position. In considering minimum press shut height, the ram adjustment is down with the ram extended to its lowest position.

Press feed height
For tools when are feed manually, the feed height is not critical. However, when dies are use in conjunction with automatic feeding devices, the height of the stock line of the die must be within the range permitted by the feeding device.
