When milling or drilling, or creating a tool path for a CNC machine the feed rate must be determined. Materials have rated surface speeds for a given type of cutter. The harder the material the slower the speed. Given the diameter of the tool and the surface speed, the RPMs of the spindle can be calculated.

Like Mickey D says, copper can be a royal pain to deal with. We used to run a lot of 1 1/4" round bar in the CNC lathe at work. Problem with copper is that it is SOOO malleable. It flows nearly as much as it cuts. You could make a threading pass and sometimes it would actually INCREASE the outer diameter, as the metal flowed around the tool.

• An alloy (mixture) of iron and carbon (<2.0%) • Plain Carbon Steel contains Manganese (>0.25%) • Alloy steels contain additional alloying elements, typically C, Mn, Si, Cr, Ni, Mo, Al and sometimes Ti, V, Nb, W, Co. • Typically Steels have 95% or …

Use octagon inserts for general face milling. With eight cutting edges, they generate smooth cuts. Use round inserts for roughing and heavy cuts. Their shape makes them stronger than octagon and square inserts. Use square inserts to create a 90° corner when shoulder milling. Carbide Inserts Octagon Insert Round Insert Square Insert
