What is Grid Marking Methods in Metal Forming about?
This document discusses grid marking and measurement methods for evaluating sheet metal formability. It describes how grid marking involves printing precise line patterns on sheet metal blanks before forming, and how the grids deform according to the local strain experienced during forming. Two common grid marking methods are described: electrochemical etching, which is low-cost and does not distort the sheet metal; and screen printing. Grid measurement after forming can provide experimental strain data to
