Chamfer Feed & Speed - G-Wizard?

[Tenson]

I just gave it a try and found it works best a fair bit higher RPM than one might expect. I'm going for 2500mm/min and 12,000RPM. Not surprisingly it cuts well at the wider part of the cutter at lower RPM, but I get a bit of tear-out near the point so it seems to work with higher RPM.

I'm cutting on both sides of the bit. Anyway I found what works well :)

I realise G-Wizard has a V-Bit option but it is really for engraving so expects the whole depth of cut in one pass.

If cutting on both sides of the bit, i.e. V-carving, then it makes sense that the rpm should be quite high, otherwise the centre of the bit isn't moving fast enough to cut efficiently.
