CAD (Computer-Aided Design) and CAM (Computer-Aided Manufacturing) are two different but related technologies used in the design and production of products.
CAD primarily focuses on the design and creation of digital 2D or 3D models and drawings of products or structures. It helps engineers, architects and designers to create detailed visual representations of their concepts. CAD software allows users to create and manipulate geometry, define materials, add annotations and simulate how the designed object will function or look. It's primarily used for drafting, modelling and visualisation.
CAM, on the other hand, focuses on the manufacturing and production aspects. It involves using computer software and machinery to automate and control the manufacturing process based on the CAD design. CAM translates the digital design into instructions for machines and tools. CAM software takes the CAD design and generates toolpaths and instructions for CNC (Computer Numerical Control) machines, 3D printers and other manufacturing equipment. It determines how to cut, shape or build the physical object based on the digital model.
Together, CAD and CAM (US Site) streamline the product development workflow and help bring digital designs to life in the physical world.
