ABSTRACT:
A machine tool frame is disclosed which is comprised of twelve struts connected together at their ends in six nodes to define the eight triangular panels of an octahedron. Forces generated by the operation of the machine tool are received by the frame at its nodes, being the nodes of opposed parallel triangular panels, upper and lower, in the specific examples illustrated. The octahedral frame displays superior rigidity due to its inherently closed kinematic loop, and to the virtual absence of bending stress in its constituent members accomplished by nodal loading. Movable machine elements are mounted upon six extensible and retractable servo-struts emanating in pairs from the nodes of a given triangular panel of the octahedral frame while opposing fixed elements located within the octahedral frame are supported tripodally from the frame nodes associated with a single triangular panel of the frame.
