  • Planar positioning system and method of using the same
    Patent number: 9898000
    Abstract: A positioning system having a flat base comprising (i) a X-axis assembly having a X-axis linear actuator means arranged orthogonal to the Y-axis; (ii) a Y-axis assembly having a pair of Y-axis linear actuator means mounted onto the flat base forming a H-configuration; (iii) a Z-axis assembly having an aerostatic bearing mechanism that floats on thin film of externally pressurized air on top of the flat base; and a ?-axis actuator anchored from the X-axis to drive the Z-axis assembly which carries a workpiece, wherein the Z-axis assembly is rotated with the rotary axis for the ?-axis perpendicular to the flat base.
