Generation of Welded-part Geometry with Manufacturing Process Rules

Abstract

Welding process is one of key processes in industry, but weld-joint geometry, such as grooves and fillets, is not easily generated from given parameters. To support the generation of welded-part geometry, a rule based system is proposed and implemented. First of all, geometry of raw material is refined by shifting or cutting suitable for welding. An IF-condition of the rule consists of geometric parameters and user defined parameters. A THEN-clause of a rule is a procedure of generating a weld-joint geometry, which sweeps a cross section of groove or fillet weld along the surround loop of contact faces between raw materials. Welded-part geometry can be generated by set operation between weld-joint geometry and raw material.
