I can adjust DOC and WOC in a certain range, but using very small tool diameters e.g. 0.5mm with 4mm length (12mm stickout due to the conical shape) in C18200 the numbers are incredibly small. E.g. a DOC of 0.5mm leads to 2% WOC, a DOC of just 0.1mm only to a WOC of 10%. I haven't practiced it yet, but it seems to be too pessimistic? 

If I enable the slotting checkbox, the DOC field remains editable and I would assume that the F&S changes according to the DOC, but it seems to reduce to a certain fixed amount and doesn't react on changes. Apparently this happens when the tool is considered overloaded. I think that it should issue a warning about tool overload or set the feed to 0 as an indicator instead of some random low number?

My material should be rather C18000, not C18200. Any chance to get parameters for that? I think it is even harder than C18200 and the DOC would drop to zero, so maybe (I hope) there is an error for small diameter calculations?
