Overview:
A 3/4" steel plate is cut to size and finished with two different end mills in the process of making an 8" chuck adaptor plate.

This video reviews a standard milling operation on low carbon steel. The task involves creating an 8" diameter circular plate from an 8.5" x 8.5" x 0.750" square plate.

Material: 1018 Steel
Cutter: Cobalt HSS rougher
1/2" 4 flute end mill
1/4" HSS 2 flute
Speed: 700 -1200 RPM
Feed: 1-4 IPM
Machine: Tormach PCNC 1100

Background:
Mild steel was used to make chuck adaptor plates. The process involved 3 operations using 1/2" roughing end mill. These were 1) cutting the circular shape from a rectangle, 2) squaring off a chamfer left behind by a face mill, and 3) finishing the outer diameter. Finally, we switch to a 1/4" end mill and put a precision cut on the pilot. Climb milling was used throughout.

    At a guess the machine doesn't have much power but you should be able to feed at least 4 times faster at that rpm and doc.
    The chips are too thin and probably not evacuating the slot properly if you only go slightly harder, get it up to a decent chipload and it'll clear itself and fly.

    Sorry if this is old news, but by god that was slow!

    I'd save the endmill and rough it with a waterjet machine first to round it. Good and no plasma cut or lazer cut hardening of edge.
    Nice work,
