## Technical Data

 To Calculate Required Tonnage for Pierce and/or Blank Operations Total the linear inches of cut. Multiply this total by the material thickness. Multiply the number by the material shear strength inpounds per square inch (PSI). Divide by 2000 (lbs/ton) for the number of tons required. ( _____ inches x thickness x PSI shear divided by 2000 = tonnage)______________________________________________________________________
 To Determine a Scaled Dimension inches x scale = _____ divided by 12 = _____ feetExamples:8.75 inches x 16 (1/16 scale) = 140.00 divided by 12 = 11.66 feet1.00 inches x 16 (1/16 scale) = 16 divided by 12 = 1.333 feet _____________________________________________________
 Typical Material Shear Strength (PSI)"Soft" Aluminum, Brass or Copper - 30,000 to 40,000 PSI"Hard" Aluminum or Brass and Low Carbon Steel - 40,000 to 60,000 PSI"Mild"/"Medium" Carbon Steel - 50,000 to 80,000 PSIStainless Steel (1/4 to Full Hard) - 60,000 to 145,000 PSI"Hard" Bronze, High Carbon Steel, Spring Steel - 100,000 to 200,000 PSI____________________________________________________
