ABSTRACT:
This invention relates to a machine tool providing a unique approach towards positioning and movement for a workpiece and tool in numerical control machine tool applications. The goal is to provide decrease machine costs and maintenance. Current machine tools such as milling machines principally rely on linear sliding mechanisms to position a table and workpiece relative to a spindle and provide motion for cutting. In accordance with this invention motion and positioning is achieved through less cost and readily available mechanisms through use of a plurality of revolute joints. Arms are provided having tangential actuators featuring extremely high stiffness and zero backlash actuator capable of a high degree of positioning accuracy. The arms resemble three dimensional truss structures for added structural stiffness characteristics. Preferably a cable drum type tangential actuator is employed in conjunction with this invention. A number of revolute arms can be linked together each providing revolute motion about offset axes to provide number of degrees of revolute motion required for a given application.
