I’ll try to post a video of what’s going on but I notice that the spindle sounds like it’s loosing RPM and then correcting for it even when there’s a constant chip load. At first I thought it was something funky with my material (6061-T6) but it’s had the same behavior on a few different samples. If I try to push it any harder than what’s below the spindle stalls.
Should I be taking a significantly smaller cut? It seems like the only way to get the job over with faster is to take light passes at high feed rates. I’m used to milling with a Bridgeport so my intuition is usually incorrect when it comes to the Nomad.
