IDEFIX: Tools and methods for ideal fixturing of mechanical workpieces with modular systems

The IDEFIX project has developed a methodology for the determination of modular fixtures for prismatic workpieces. This methodology has been implemented in a software tool, namely the IDEFIX system.

Given the workpiece description in the form of features, the IDEFIX system determines the minimum number of set ups needed to machine the workpiece. For each set up, it determines the positioning, supporting and clamping locations in contact with the workpiece (the so called virtual fixture) and finally it designs the physical fixture based on modular fixturing elements.

Within the IDEFIX project another methodology and the corresponding software tool have been developed for the technical economical justification of the use of the modular fixturing system for a given enterprise.

Some further developments are necessary to produce a fully operational system in industrial environments. Efficient interfaces should be developed to retrieve the workpiece information from a computer assisted design (CAD) system.
The T9 module which takes care of the determination of the physical fixture once the virtual fixture has been determineed by the previous modules, is the closest to commercialization.
