About 300 miles east, near Spokane.
I was leaning towards a feed problem way back, it was the only point you didn't cover, but with everything else good it looked like maybe materials. It happens, the stuff all looks the same. Someone drops something at the warehouse and puts it back..?
I work in chipload, the mill is graduated that way, and this might be way off, but I'm seeing a 2-flute endmill spinning at 800 RPM should take about 2-3 minutes to travel 4 inches.
I came to that with a .002 chipload. 2 flutes means it traveled .004" in one revolution. Times 800 revolutions per minute works out to 3.2 inches per minute.
Almost certain you can do .004" and cut that time in half, and a four flute half again - 30 seconds to cross. The .002 is just starting point.
Someone please stomp me if that's wrong.
