Abstract: A reconfigurable, intelligent modular fixture with embedded sensing capabilities is critical to improving the adaptability and efficiency of meso-milling machines for yielding micro-size features. The primary goals in designing such a fixture are: 1) to locate a large group of similar workpieces with minimal setup changes; 2) to sense the location of a workpiece placed on the fixture; 3) to provide feedback in regard to ongoing proper workholding of a workpiece during machining. We consider two specific issues to address these goals. First, designing a set of modular fixture components with desired stiffness and accuracy. Second, employing miniaturised and accurate embedded sensors.

Keywords: meso-milling; reconfigurable fixtures; intelligent fixtures; embedded sensors; modular fixtures; fixture design.
