What is involved in the die tryout process for new stamping tools?

Die tryout validates new tooling before production: Initial tryout assesses basic die function (drawing, binding, ejection), identifies major issues requiring die modification; subsequent tryouts refine forming (adjust spotting, binder pressure, timing); dimensional tryout confirms part meets specifications using CMM and checking fixtures; appearance tryout evaluates surface quality; and production tryout validates at full rate with automated handling. Issues addressed include splits, wrinkles, springback, surface defects, and dimensional deviation. Die modifications include welding/grinding, shimming, and spotting. Tryout duration significantly impacts program timing and is a focus of virtual tryout efforts using simulation.
