All You Need To Know About 5 Axis Machining CAMplete

The United States Air Force awarded Cincinnati Milacron a contract to build and test an electric tracing of a 5axis vertical mill to determine its feasibility. This machine was seen by many to be outside the realms of reality, earning it the nickname the "Opium Mill." 5 axis machining today is however in fact very real, and very effective.
