Engraving Aluminum with v-bit .04 doc

[Julien]

I have no hands-on experience of using Vbits in aluminium, but @Vince.Fab had this to say, and he does have experience:

I usually compensate with varying router speed as the cut deepens.

In my experience V bits are extremely durable but I also use good bands, Kyocera and Destiny. The flat on the end on mine are around 0.010 and they have cut pretty much everything without chipping out or any issues. On feedrate, really depends on the material but the end of the cuts with v carving will usually be around full engagement and it can have a tendency to chatter if you don’t keep an eye (metals). Lubrication is important in metals, especially the first few passes, helps with the tip sfm issues. Keep in mind you can also use v bits for adaptive cutting, I like a 0.009 opt for two flutes (has to be less that tip flat diameter)

I did not quite get your speed, is it really 1800 RPM ? or is it missing one zero and it’s really 18.000 ?
