Abstract
A three-axis machine is disclosed. The machine includes a machine component to which a workpiece or tool can be attached. An actuator, such as three powered extensible legs, is connected between the machine component and a support structure. Three control arms also are connected between the machine component and the support structure. Preferably, each control arm is pivotably connected to the support structure and 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 rotational movement of the machine component along the rotational axes.
