Manufacturing Processes

Manufacturing Processes encompass the wide array of techniques used to transform raw materials, components, or parts into finished goods that meet specific design specifications. This fundamental area of mechanical engineering includes subtractive methods (e.g., machining, grinding), formative methods (e.g., casting, forging, molding), joining processes (e.g., welding, brazing), and additive manufacturing (e.g., 3D printing). The selection of an appropriate process is critical as it directly influences a product's final geometry, material properties, surface finish, and overall production cost, effectively bridging the gap between theoretical design and physical reality.
