An Automated Design and Advisory System for Pressed-and-Sintered Powder Metallurgy Parts

• The aim of the present paper is to dissolve the bottleneck for PM market expansion caused by lack of knowledge among designers about PM-specific design principles by proposing an automated PM-part advisory system. The system, called PM-Wizard, checks that a PM-part design suggestion represented as any 3D solid CAD-model complies with the geometrical design rules and recommendations for PM-parts. The system consists of a rule-base hosted by a modern commercial CAD/CAE-system and a programmed algorithmic procedure that converts the design suggestion into a specially developed format. The format enables the automated evaluation of the PM-part in the receiving CAD/CAE-system informing the designer on how the geometry should be revised to facilitate the pressing. The conversion algorithm has been tested on a large number of PM-parts, and the result is that all the tested parts can be converted into the proposed format and successfully evaluated.
