V-bit feeds and speeds ballpark: yay or nay?

[Julien]

A while ago I tried to collect data to come-up with a baseline set of feeds and speeds for V-bits, based on what people happened to use, since there is apparently no good way to determine them theoretically due to the weirdness of their geometry and toolpaths (i.e. chipload-based approach does not work very well for V-carving)

I’d like to at least have a ballpark set of values to mention in the e-book, and as far as I can tell after reading a number of posts and comparing to my own notes, the feeds and speeds for 60 and 90deg Vbits in wood are typically like so:

• RPM in the 16-20k range

• Feedrate in the 30-60 ipm range

• Depth per pass in the 0.1-0.2" range

• Plunge rate in the 10-20 ipm range

I’ll be happy to hear from you all, whether the values you use for your V-carve jobs fall in those ranges, or not. Noting that these are intended to be “comfort zone” settings, not aggressive ones.

0.1 doc, 40 to 50ipm (depending on type of wood), 4+ setting on dewalt. 20ipm plunge (HDZ)

however one variable you haven’t covered yet is if you do a roughing pass first. If you do a proper roughing pass first you can push the F&S much higher in my experience.
