This work describes a micro-patterning and surface texturing technique on the fixed work surface using a proposed new spindle system with a rotating cutting tool controlled in real time.
The shaft of the spindle is suspended by air bearings, and an electromagnetic actuator controls the radial motion of the spindle housing instead of the shaft. This generates a micro-sized patterns or digital image on metal surface using rotating tools such as a micro-milling tool and a micro-grinding wheel.
The machining results show that this compensation improves the pattern accuracy. It is expected that generating micro-patterning and digital image using the proposed spindle system can be applied over a large surface area
