CAM (Computer-Aided Manufacturing)

Computer-Aided Manufacturing (CAM) software generates the machine-ready toolpaths, G-code, and setup instructions that CNC machines use to cut, mill, turn, or otherwise manufacture physical parts from digital geometry. CAM takes geometry from a CAD model as input and produces machine control programs as output. The quality of a CAM system is measured by its machining strategy library, postprocessor ecosystem, simulation fidelity, machine coverage, and the degree to which it can automate programming for repeatable part families.

Why it matters

CAM is the critical bridge between the digital product definition (CAD/PLM) and physical manufacturing (CNC machines). The quality of CAM programming directly determines cycle times, surface finish, tool life, and machining costs. A poor CAM decision increases programming time, reduces programmer productivity, and creates a gap between what looks good in simulation and what happens on the real machine — a gap that manifests as scrap, rework, and missed delivery.
