CNC manufacturing involves the use of computer-numerical-controlled machines to automate the fabrication process. If you've never come across a CNC machine before, picture this: it sounds like a roaring jet engine, resembles those massive air hockey tables, and works as a computerized wizard guiding a router for ultra-precise (often down to fractions of a millimeter) cutting. These machines follow precise instructions to cut, shape, and carve materials into desired forms.
