What is a common example of a subtractive manufacturing technique?

Milling is a common example of a subtractive manufacturing technique because it involves removing material from a solid block or sheet to achieve the desired shape or dimensions. In milling, a rotating cutter is used to cut away material, allowing for precise control over the final geometry of the workpiece. This process typically uses machines that can move in multiple directions, which adds to the versatility and precision of the manufacturing technique.

In contrast, 3D printing is an additive manufacturing process that builds up layers of material to create a part. Welding joins materials together, rather than removing material from a workpiece. Laminating typically involves bonding layers of material together without removal of material, focusing instead on enhancing structural integrity or aesthetic finishes. Therefore, milling stands out as a definitive example of a subtractive technique.
