Abstract:

Assembly sequence planning can be generated automatically with an optimization algorithm according to the assembly direction of parts and their interferenceon this direction. The problem is that it is difficult to get the assembly direction automatically. Based on the B-rep model and surface contact characteristics among parts,  a new method that could identify and extract assemblydirection of parts was proposed. The effectiveness of this method was verifiedwith an example.

Key words: assembly sequence planning; contact characteristics; assembly direction; identifying restriction
