How should we determine the assembly order of different part

How should we determine the assembly order of different parts in an assembly model?

Solution

Parts can be positioned within the assembly order using absolute coordinate placement methods or by means of mating conditions. Mating conditions are definitions of the relative position of components between each other; for example alignment of axis of two holes or distance of two faces from one another. The final position of all components based on these relationships is calculated using a geometry constraint engine built into the CAD or visualization package. the automated procedure for assembly sequence modelling can be expalined in a theoretical comparision example.Either Assembly Sequence Planning or Assembly Sequence Analysis depends on the information and the knowledge available for a product in a assembly process.Such information could be retrived from virtual 3D models, so Computer Aided Assembly Plannig is the one depends on the relationships between the parts like coplanar, coaxial, mate,angle, etc. This is essential to get the exact feasibility of the identified assembly sequences.
