👉 Fitting engineering, also known as mechanical fitting, is a specialized field within mechanical engineering that focuses on the design, selection, and installation of components and assemblies to ensure they work seamlessly together. It involves understanding the physical properties, tolerances, and compatibility of various parts to create systems that function efficiently and reliably. This process includes precise measurements, material selection, and the application of engineering principles to address potential issues such as stress, vibration, and thermal expansion. Fitting engineers must also consider manufacturing constraints and ensure that the final assembly meets both functional requirements and safety standards, often utilizing CAD software and simulation tools to optimize designs before physical prototypes are built.
