Hi guys,

I need to do a 45deg chamfer on some Walnut with a 2-flute TCT bit. The total depth of the cut will be 9mm and I can do it in multiple passes (I was going to use 1mm passes).

Can anyone advise how to calculate the optimum feed and speed? I suppose the answer is, there isn't one since the tip will have a far lower surface speed than the wider section. Or perhaps I need to reduce the RPM as a take each deeper pass?

I do have G-Wizard and I can select a 45deg V-bit but I'm not sure if I should tell it the depth per pass or total depth or what.
