Assembly in Manufacturing

Assembly is the capstone process in manufacturing. It brings together all the upstream processes of design, engineering, manufacturing, and logistics to create an object that performs a function. A great deal must be known about how the unit functions and the processes that are required to fabricate and inspect individual parts.

Assemblies are the product of the assembly process, but they are also the product of a complex design process. This process involves defining the functions that the item must perform and then defining physical objects (parts and subassemblies) that will work together to deliver those functions. The structure of the item must be defined, including all the interrelationships between the parts.
