• Assembly is a manufacturing process in which
parts (usually interchangeable parts) are
added to a product in a sequential manner to
create a finished product much faster than
with handcrafting-type methods system. The
parts made in machining, welding,
woodworking, electric fitting & gear making
are assembled together to make an assembly.
