As technology and computers have improved over the years, a new high-precision computer controlled manufacturing technique called CNC machining has spawned. CNC machines, or computer numerically controlled machines, are electro-mechanical devices that can manipulate tools around a varying number of axis, usually 3 or 5, with high-precision per instruction from a computer program. CNC machining is one of two ways that engineers, machinists, or makers can generate a physical part from a computer design file, with the other being 3D printing, known as additive manufacturing.
