Abstract
A three-axis machine control structure includes a support structure and a machine component to which a workpiece or tool can be attached. Three control arms are connected between the machine component and the support structure. Preferably, each control arm is pivotably connected to the support structure and to the machine component and includes a pair of four-bar linkages connected in series. The control arms are oriented to permit rapid movement of the machine component along any or all of the three linear axes, while restricting movement of the machine component along the rotational axes.
