CNC machining operates through subtractive processes, wherein the feedstock is machined to its
final form by the removal of material. This involves drilling holes, boring lots and pathways,
and shaping metal stock into new material with varying tapers, diameters, and shapes.
In subtractive manufacturing, the achievement of shapes relies on the removal of material,
a distinctive feature when compared to additive manufacturing methods that involve the addition,
layering, and deformation of materials to achieve a specified shape.
It also contrasts with injection molding, where material is injected in a different state of matter
using a mold and formed to a predetermined shape.
