The factors affecting stamping parts in the production process are complex, and the correct use of grid test can effectively guide the optimization of necking and tearing of stamping parts qualitatively and quantitatively, can make stamping parts have a greater “Safety margin” in the stamping process, thus speeding up the speed of problem solving. Through Forming Limit Curve(FLC) analysis and Comsmart equipment measurement, the production guidance data can quantify and reflect the actual status of the mould, and then make specific mould margin adjustment and verify the adjusted mould margin.
