ABSTRACT:
A multi-axis computer numerically controlled machine tool is provided in which a cutting tool is movable relative to a workpiece by a number of linear and rotary joints under the control of a programmable control unit. The machine is programmed with a plurality of principal programmable axes, called "hard" axes, and with at least one synthesised additional programmable axis or "soft" axis which enables the cutting tool to be moved linearly in the direction of the soft axis without requiring a specific joint for that purpose. The synthesised "soft" axis is a non-collinear, partially redundant axis which increases the number of programmable degrees of freedom to a greater number than the machine degrees of freedom, i.e., the number of non-collinear joints. The principle of synthesising "soft" axes may be extended to CNC machine tools having four or more principal hard axes, for instance, to produce a 5-joint CNC machine tool which has the flexibility of a conventional 7- or 8-joint machine tool.
