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.
