What Is thinning percentage during sheet metal forming?
How much it is allowed as per SES (Suzuki Engineering Standard) and is it same for high tensile or different ? what is the SES number for the allowed limit for thinning during forming?

Is it not a simple volume calculation or is the specific gravity of metal changed by forming?

Or are you concerned about variations in thinness/thickness of the formed metal?
