Abstract
An axially compliant tool assembly for a programmable position controller is disclosed. Various construction details have been developed which provide a responsive means to make the tool axially compliant to deviations between the programmed path of the tool and the surface being worked upon by the tool. In one particular embodiment, the axially compliant means includes a base, a sleeve axially movable relative to the base, a tool disposed on an internally splined shaft, and a radial bearing disposed between the shaft and the sleeve. The sleeve includes a flange which defines in part two sealed cavities wherein the differential pressure between the two sealed cavities provides a working force for the tool and wherein the flange may move axially within the limits of the sealed cavities.
