Max IPM question
I am getting close to getting my build done. I have things setup to do some testing. Everything was fine cutting wood, single flute .125" endmill 10K RPM and about 8-10 IPM. BUT when I tried cutting some parts from aluminum everything went to crap. I realized that I am cutting to slow for the single flute endmill. I did a little web searching and it looks like I should be running at 100 IPM? The best I can get my machine to do is 50 IPM, above 55 it will stall. I have played with the driver settings, thinking fewer micro steps and I would be able to increase IPM. But it didnt seem to matter. So right now it is set at 16140/inch. would I be better off going to a 2 flute endmill? right now I am using a 1.25hp Makiata router.
power supply is 14VDC.... would going to a higher voltage supply have any effect?
most of my projects I have planned, I would be cutting 22ga-.5" 6061 aluminum sheet/plate.

Re: Max IPM question
I would consider 50ipm to be very good for 14V. Speed is roughly proportional to voltage.
What motors and drives are you using? Is it a screw drive?
Without seeing your machine, it's hard to say, but I'd guess that you'll probably want to be cutting aluminum at about 30ipm, with a depth of cut of .01-.02"
