Problem is they don't make and use wood pattern gauges to check the parts they make. They load tooling onto the CNC bender and enter the program they have for the part. Then they check it with a laser "Romer" and it averages the straight length sections to determine if it's close. Trouble is every time you load the tooling you have to have it set up EXACTLY the same as the times before or you will get different bends. Over the length of a 6 foot line it can read OK on the romer but actually be way off. Thats where the wood gauge comes in. You can tweak the pressure settings to correct the bends until the part fits the gauge correctly so they are consistent from run to run.
