Punch Press Estimating and the First CNC Punch Press

Posted by Dave Ferguson on Jul 10, 2015 7:23:46 AM

Punch press estimating is a very common way to put wholes in sheet metal parts. Punch presses have been around since 1955.  The Wiedemann Machine Company was established in Philadelphia, Pennsylvania in 1916 and over the years developed and produced a variety of machines. Wiedemann unveiled the world's first NC turret punch press at a machine tools show in Chicago in 1955.

CNC punch presses are very common and still outperform laser in many scenarios in speed.

Punch press formulas for estimating usually ask for number of hits, tools and thickness of material.   You can see a sample formula below which can be changed based on your machine capabilities.

PunchPressFormula

((onehit*.0008*((thickness*2)+1))+(nonstand*2*.0008*((thickness*2)+1))+(perimeter/668*((thickness*2)+1))+(((length/4590)*2*tools)+tools*.05))
