Abstract
A machine element support comprised of a plurality of axially extensible and contractible servostruts which are individually adjustable and collectively controllable. The struts comprise an outer tubular member and a slidably, interfitted, elongated, inner member. The powered servostruts are movably connected to an machine element such as a spindle head by one of the members on one end and to a rigid machine tool frame by the other of the members on the other end. Linear position sensors mounted on the servostruts serve to precisely measure strut extension and retraction for feedback control purposes. A preferred servostrut configuration is a hexapodal array, in which two servostruts are mounted side by side in each of the three well-known orthogonal axes of machine tool practice, providing six-axis movement and positioning of the tool head or workstation relative to the workpiece.
