Machining soft jaws remains one of the most tedious and time-consuming tasks for turning centers, so anything you can do to organize and simplify this task will speed up your setups. In order to make the workholding setup when soft jaws must be machined, the setup person must
remove the current top tooling from the chuck,
find the set of jaws to be used for the new setup,
mount the jaws to the chuck,
clamp on some form of temporary plug or ring, and
machine the jaws.
Almost every offset entry requires some kind of calculation to be made before the offset value can be entered. Say, for example, the target diameter for a turning tool is 3.
