Product Drawing
The roll designer reviews the product drawing and final profile to generate the new roll form tooling drawing. Once the designer has this information, he can determine the practicality of changing the roll form tooling.
At this point the roll form tooling has to be shadow-graphed and measured (see introductory photo). Each pass and each roll must be put into an optical comparator that projects an image scaled 10 times the original size onto a screen. This image has to be traced by hand to examine the current condition of the roll form tooling and compared to the product drawing.
Typically this can be done in about a week, depending on the size of the roll form tooling and the number of forming passes. Companies that offer this service can work with the customer to minimize the amount of lost production time by doing a few passes of roll form tooling at a time.
