Abstract
In a cutting machine having an octahedral framework, a cutting tool is carried by a servostrut support having a platform mounted on extendable and retractable struts. In order to reduce deflections and to limit transfer of bending moments, from the servostrut support to the other connected support sections of the framework, the six struts are mounted at pivot mounts such as ball joints in a triangular support. Three of the pivotal mounts are positioned in a first triangle and in corners of the triangle support, and the other three struts are positioned in a second larger triangle in the triangular support. The nominal axis of rotation of spindle drive for the cutting tool may be either about nominal horizontal axis, a nominal vertical axis or a nominal 45.degree. axis. Several frameworks may be arranged to define a hollow tunnel with platforms projecting their cutting tools from opposite sides of the transfer tunnel.
