Hi all,

Since my last update I've been doing some research on feeds and speeds and trying to understand the relationship between the two (amongst all the other variables).

I've used GWizard and also FSWizard to compare results and tried to compare to the advice I've had and I certainly need to use 2 flute (or even single flute) cutters to bring the speeds and feeds down (ordered a bunch and they should be here Monday or Tuesday).

Also I am a bit mystified on one thing: HSS vs Carbide end mills - Carbide F/S results from the wizards above seem to be way way higher than HSS and I know that carbide is alot stiffer, but do the carbide end mills actually need to be run at the multiples higher than HSS given the same geometry should result in the same chip loading? Or is there some other factor I'm not grasping?

Off to try and make a mount for my airbrush/mister :-)

Cheers


Chris
