Abstract: Apparatus are provided for automatic repositioning of fluid nozzles when operating on a workpiece with a tool. The apparatus includes a nozzle assembly configured to convey a fluid to a target zone defined on the workpiece and/or on the tool. The target zone has a location that varies over time. A spring applies a spring force to bias the nozzle assembly toward the target zone, and moves the nozzle assembly as the location of the target zone varies. The nozzle assembly moves to a position relative to the target zone by a combination of action of the spring force and of any hydrodynamic force of the fluid, when moving through the nozzle assembly.
