This paper presents software to assist the tool designer of modular fi
xturing assembly. The software comprises a knowledge-based Adviser, a
fixturing component assembly program and a CAD system. The Adviser ass
ists the tool designers in selecting components from a modular fixturi
ng system (MFS). The fixturing component assembly program will then po
sition and assemble the modular fixturing components. The final assemb
ly is then displayed in the CAD system. An example is also included to
demonstrate the working principle of the software.
