CAM (Computer-Aided Manufacturing)
Computer-Aided Manufacturing (CAM) is the software discipline and toolset for converting a finished CAD design into machine-executable instructions — primarily toolpaths and G-code — that tell CNC machines how to cut, shape, and finish material into the desired part. CAM is downstream in the product lifecycle — it owns manufacturability and the execution plan. CAM consumes CAD geometry as input and outputs machine code.
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.
