Abstract
A non-contact support platform with open-loop control, including: a surface, to support a workpiece by fluid-bearing of fluid flowing through a plurality of nozzles, a supply system, connected to the surface and configured to maintain the fluid-bearing by applying pressure to cause flow of the fluid out of a subset of the plurality of nozzles, and a controller, to control fluid flow in the supply system with an open-loop circuit to support the workpiece while it moves over the non-contact support platform, wherein the fluid flow is controlled based on at least parameter of a group of workpiece parameters consisting of a position of the workpiece, dimensions of the workpiece and a velocity of the workpiece while supported by the surface.
