Punch Press Estimating and the First CNC Punch Press

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))

David Ferguson has been to over 100 manufacturing companies helping and guiding them to be more efficient and cost effective. As a child in Junior High School David Ferguson found a passion for the early computer systems, which would drive much of his future work. David Ferguson created and sold his first computer program, Arrow Data Systems, which was an early CAD/CAM system for the Apple 2e Computer. In the late 1980's after seeing his father (a sheet metal manufacturer) come home many nights estimating, David Ferguson saw an opportunity to optimize his effort through computer technology. Shortly thereafter the FabriTRAK Production Control package was developed. The Quote It! estimating package was developed out of the FabriTRAK system to become one of the leading sheet metal estimating packages in the world. David Ferguson has always had a passion for developing software to make the manufacturing process simpler, faster and more efficient. Prior to founding MIE Solutions David Ferguson worked with his father at Alco Sheet Metal, METALSOFT Inc. and was a consultant at Toyota Motors Sales. David Ferguson has his Masters in Computer Science and Mathematics from California State University, Long Beach.
