In production and operations management, Computer Aided Design (CAD) and Computer Aided Manufacturing (CAM) are two critical technological systems that support the planning, design, and execution of manufacturing activities. They play a central role in improving productivity, quality, flexibility, and competitiveness of modern manufacturing organizations by reducing dependence on manual processes and enabling faster, more accurate decision making. Computer Aided Design refers to the use of computer systems to assist in the creation, modification, analysis, and optimization of product designs. In operations management, CAD is primarily concerned with the design stage of the production system. It allows engineers and designers to develop detailed graphical representations of products, components, and assemblies using specialized software. These designs may be in two-dimensional or three-dimensional form and include precise information about dimensions, tolerances, materials, surface finish, and functional relationships between parts. CAD systems replace traditional drafting methods and provide higher accuracy, better visualization, and easier modification of designs. The use of CAD begins with conceptual design, where basic shapes and configurations are created to meet functional requirements. As the design progresses, CAD tools allow designers to refine geometry, test fit and assembly, and evaluate alternative designs quickly. Advanced CAD systems also support engineering analysis such as stress analysis, thermal analysis, __________ _________ ________ ____ ______.
