I found some nice endmills but when I looked at the recommended feeds and speeds, I saw this table:
I’m running a Nomad and so of course can’t run my spindle at the 22k-33k RPM or 12k-17k RPM for 3mm and 6mm endmills respectively.
And to put those numbers in m/min, it’s 207-302 m/min for the 3mm endmill and 226-320 m/min for the 6mm endmill.
So hopefully easy question, what’s the impact of running at 185 m/min instead of 226 m/min for a 6mm endmill, or 94 m/min instead of 207 m/min for a 3mm endmill?
In case anyone is wondering, the endmill is Sumitomo’s DLC-coated ASM series. Page 130 of the catalogue.
