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
Without CAM, turning a CAD design into a manufactured part requires manual G-code programming, which is slow, error-prone, and wasteful of tool time. CAM automates the conversion from geometry to machine code, accounting for available tools, spindle speeds, feed rates, coolant strategy, and the target tolerance. CAM also simulates the toolpaths before they're run, catching collisions and errors before they scrap a part. In modern manufacturing, CAM is where design intent gets translated into manufacturing reality — and where unmachinable designs get caught.
