Mechanical module interfaces for reconfigurable machine tools

Reconfigurable manufacturing systems (RMS) enable industrial companies to adapt to frequent and unpredictable changes of production requirements in a cost-efficient way. RMS are constituted by modular machine tools that provide variable overall functions with the ability to add, remove, rearrange and replace functional sub-units. The performance of these machine tools as regards the quick and flexible arrangement of modules and high work piece quality strongly depends on the properties of the mechanical module interfaces. In this paper, performance parameters for mechanical module interfaces were defined and their influence on the machine tool’s performance discussed. Then flexibly arrange-able quick-coupling interfaces as a promising solution for module assembly were analyzed. Finally, tools for the determination for those interface performance parameters are presented, which require technical testing.
