Copper is soft and sticky so you need more room for the cut material to clear the cutter especially making slots. The other observation is that copper is much tougher on mill bits than steel because it tends to stick to the mill bits it causing greater local heating of the mill bit cutting edges. the heating dulls them faster than steel cutting.

3 flute endmills work well in C110. speeds and feeds not as fast as aluminum, but faster than mild steel, BUT the d.o.c. and width of cut are reduced quite a bit. Again, this is if you're running C110. I'd go at least 700sfpm with .004ipt. Full flute length of cut and 10% stepover. 09-23-2015, 04:40 PM #8.
