About this document
Punch Buckling and Clearance Calculations by Godwin J. Sobin is a document available to read on EtoBox.
This document discusses buckling in punches used in press tools. It defines buckling as the failure of a structural component under compression when it is thin or longer than its width. Punches can fail due to buckling if the compression stresses during pressing are not properly accounted for in tool design. A formula is provided to calculate the maximum force a punch can withstand before buckling based on its material properties, length, and cross-sectional moment of inertia. Two examples show how to apply
