A computer tool to extract feasible assembly sequences from a product CAD model, in automated way

Purpose: Justify the capability to obtain feasible assembly sequences through an automatic approach based only on contact and interference information between components of a mechanical discrete product, independently of adopted virtual modelling techniques and human intervention. Analysis of assembly information available at early stages of design in virtual model of a product in order to identify reliable information to be used in a systematic methodology based on identification and evaluation of subassemblies. Result: Methodology and computer tool to automatically extract possible assembly sequences for mechanical discrete products, starting from topological contact information between components, and guaranteeing at least one feasible solution. Results show that this approach allows obtaining automatically a lower finite number of assembly sequences than theoretical approaches with human intervention, in a faster way to be implemented at early stages of design using virtual model.
