Circular Interpolation Machining Circular Tool Paths

All rotating end mills have their own angular velocity at the outside diameter But when the tool path is circular there is an additional component that is introduced resulting in a compound angular velocity Basically this means the velocity of the outside diameter is travelling at a substantially different velocity than originally expected The cause of the compound angular velocity is
