Using "Stock to Leave" instead of cutter compensation

Thought I'd share this as I just discovered it yesterday (seems like a no brainer now!).  Instead of adjusting for cutter comp in your control/machine you can alternatively use the Stock to Leave function under "Passes" tab.  This should give you more control of a single tool over multiple features.

The only time I think this would be useful would be if you are using the same tool for multiple features that are toleranced unidirectionally in opposite directions.

You can also duplicate your tool and just set a different tool diameter offset number for just that operation or feature. That way you can still use the wear comp in your machine to work up to any tolerance you have. I tend to stay away from using "stock to leave" as cutter comp as it starts stacking up and getting confusing when you have multiple dimensions and features you are trying to comp in.

I ran a machine with stock to leave only for tolerance compensation for years.

Now I use both, because just the cutter comp only on the machine won't work for milling. You need so many different tolerances with the same tool that usually it's a good habit to use the stock to leave boxes to make the toolpath mill at the middle of the tolerance you get. I mean you can't use cutter comp to mill a +/- 0.02 mm and a -0.05 - -0.10 mm tolerance so if you make sure the first tolerance has no stock to leave and the second one has -0.0375(Since usually doubled since on two sides) adjustment on the machine should be correct for both tolerances.

Laurens: yes, that's what I meant by unidirectional tolerance (the -/- direction). :winking_face:

We do almost none of that at my job but every once in a while the engineers try it.
