Humans by their very nature are users of tools, materials, and processes as a part of their survival and existence. As humans have progressed over time, their civilizations and societies have changed beyond imagination and have moved from hunters and gatherers of food and materials for survival to sophisticated societies with complex social and technological systems. In this context, inventions and innovations have paved the way for modern manufacturing and production ways and methods. Mathematics, science, engineering, and technology are the "tools" through which people explore, describe and explain, and create new inventions and innovations in technology. In making connections between earlier manufacturing materials, methods, and processes and the technologies of today, the authors find that people can use many of today's technologies that are similar to those found in industry in technology education classrooms. Mechanical drawings have been a fundamental communication tool used by designers and engineers, and today the drawing process is now on a digital platform called computer-aided design, or CAD. When CAD processes are connected to other technologies, it becomes possible to design and engineer products almost from a design concept or idea to a finished manufactured product using computer-aided machining (CAM) and computer numerical control (CNC). In this article, the authors discuss the integration of computer-aided design and computer-aided machining applications coupled with computer numerical controlled machines that can provide a window to new learning opportunities and technological literacy.
