CADCAM

CADCAM refers to the integrated use of computer-aided design and computer-aided manufacturing technologies to design and produce parts. CAD provides the geometric modeling and drafting tools to create 2D drawings or 3D digital prototypes, while CAM uses those models to plan manufacturing operations, select tools, simulate machining, and generate machine-ready code. In practice, CAD and CAM are often part of a single software suite that supports a seamless workflow from design to production.

The term and underlying concepts date to the development of computer-aided design in the 1960s and 1970s, with expanding use as CNC machines, digital prototyping, and interoperability standards emerged. Over time, CADCAM workflows have integrated simulation, optimization, and, more recently, digital twins. CAM supports both additive manufacturing (3D printing) and subtractive processes (milling, turning), often through post-processing to machine instructions.

A typical workflow begins with creating and refining a 3D model in CAD, followed by assembly validation and simulations of form, fit, and function. The CAM phase defines machining operations, selects tools, determines speeds and feeds, and generates toolpaths. A post-processor converts CAM data into machine-readable code (such as G-code) compatible with CNC machines or robots, and the output is verified before production.

Benefits include reduced lead times, improved accuracy and repeatability, easier change management, and automation of repetitive tasks. Challenges include data management and interoperability between software ecosystems, licensing costs, and cybersecurity considerations.

Industry applications span aerospace, automotive, consumer electronics, medical devices, tooling, and woodworking. The software landscape includes various CAD platforms and CAM systems, with many vendors offering integrated CADCAM solutions.
