feeds and speeds Recommendations for belt drive cnc

[marbles]

What size tool, and how many flutes?
What feed and speed did you use?

Try 4-5m/min at 15,000 rpm.

Hi Gerry,

Thanks for reply. I was using a single flute spiral bit. 4mm dia and 12mm cut length. Spindle set at 'No 6', which i would take to be about 26,000rpm

I'll need to get back to you about the exact feeds and speeds tomorrow. I set the feed rate in Aspire to 80mm/s in 2mm passes but of course this doesnt necessarily relate to the actual rate, which i'll work out tomorrow in Mach3.

I did notice that it was rounding corners again so that'll need a tweak in motor tuning for wood. Currently settings are for foamboard carving.

Thanks
