Development of a traverse module with micro-positioning in a macro-moving range for a modular robotic manufacturing system

Abstract

This study aims to realize the Modularized-Structure and Multiple-points Simultaneous Machining System (MS-cubic) to overtake existing CNC-based manufacturing system, which is inefficient for manufacturing huge products, such as air mobility expected to become widespread in the future. A new module named traverse module is developed to enable for machine tools to move orthogonal to rail module included in MS-cubic. Traverse module is designed to have a backlash intentionally to realize both movement in meters range and positioning in sub-millimeters range. It is revealed that proposed designed is effective for a table of traverse module to positioning with high accaracy.
