In the lingo we use in here... we take the information from the current measurement-method and correct the curve at the machine with a wrench and lead-hammer. In order to do that I need a measurement that doesn't take a half-hour in the lab to perform. Most of that is setup and teardown of the measurement equipment.
So... I use put my blade in the hypothetical Measurematic, and either by automation or manually positioning the head I get my numbers quicker, and I can correct the machine quicker.
Result, less tweaking and rework downstream.
The grinder dates from 1985, aside from the wheel-wear-comp PLC everything is adjusted by hand.
It's simply a matter of getting the data quicker so I can correct the machine quicker.
