Example:
Process sheets state air pressure to be 40 with a tolerance
of +/- 5 you could adjust the setting anywhere from 40 to 50 without having to resubmit.

Ideally you should create your process by creating a tolerance box.

Create a saturation curve for the following parameters:
Air pressure low Shot flow low
Air pressure low Shot flow high
Air pressure high Shot flow low
Air pressure high Shot flow high
