Selection of optimized assembly sequence from the available feasible assembly sequences is significantly essential to achieve cost-effective manufacturing process. To achieve this, at the outset, generation of feasible assembly sequences with topological, geometrical, precedence and stability conditions should be generated. The increase of part count in a product results huge number of assembly sequences, the Liaison matrix/Liaison graph generated based on the connections between the assembly components eliminates non-possible assembly sequences at the initial phase. There exist methods namely cut-set method to eliminate the non-possible assembly sequences using liaison graph. In this paper a new approach to eliminate the non-possible assembly sequences based on liaisons is described and the correctness of the methodology is illustrated with an example. The methodology to obtain the feasible assembly sequences is also briefly described and presented. An algorithm to interface with the CAD environment is described briefly.
