What are you trying to accomplish by cutting the drum off?
How do you plan to get the new drum back on?
The drum comes off by removing the axle shaft, then the drum, hub, and bearings as an assembly, then knocking out the lug studs that "rivet" the drum to the inside of the hub. It's a genuine pain in the ass; fixed (I have heard) on newer-model axles that put the drum on the other side of the hub.
I'd rather hear this from someone who knows what they're doing, but the way I remember it, cutting cast iron with Oxy-Acetylene is a biitch--unlike steel.
