Abstract
A mechanical control structure is used with a machine, such as a machine tool. The control structure includes a base and a tool support member connected by a linkage assembly having three linkages arranged in a triangular pattern. The linkages cooperate to prevent rotational movement of the tool support member relative to the base along any of the three rotational axes. Three linear actuators are also connected between the base and the tool support member to move the tool support member relative to the base along a predetermined path.
