Abstract
Assembly is the ultimate process in discrete parts product manufacturing. It is the procedure with the best potential to enhance product improvement techniques and manufacturing strategy. Design and creation of assemblies is intrinsically integrative. Assemblies are technically and commercially important physical products. A company can efficiently improve its prospects and succeed in production through an assembly-driven product realization process. Assembly is additionally the slightest comprehended of manufacturing processes on the grounds that individuals have constantly done it but can't clarify how they do it; it is complex at micro and macro level. This paper aims at presenting some studies on mechanical assemblies and describes the concepts such as mechanical constraints, assembly sequences analyses, assembly workstations, assembly features, assembly cost approach, assembly approach direction, assembly errors, assembly mistakes, assembly modeling in assembly motion, CAD systems, assembly difficulties, Design For Manufacturing (DFM), Design For Assembly (DFA), concurrent engineering, assembly requirements and activities of assembly.
