Subtractive manufacturing is the most common machining method used in manufacturing applications, employing tools to remove material from a workpiece. This technique is often used in CNC applications, from grinding to milling, to remove material from metals, woods, and plastics. Alternatively, additive manufacturing, or 3D printing, involves the continuous adding of a material to form a final, physical 3D object.
Both methods employ CNC programming methods to control the tooling that ultimately shapes the workpiece. Virtually any industry that has a machine shop utilizes CNC machining to create parts from raw materials or fabricate metals into components. A range of industries, including the automotive, aerospace, power generation, marine, and transportation sectors, use CNC machining technology to bring about increased precision, efficiency, and quality.
