Abstract
24 hour, unmanned operation of CIM systems requires the development of techniques for the highly reliable operation of machine tools. One possible approach is the development of fail-safe devices, which prevent damage to the machine tool when system faults occur. The authors Lave developed a system which has high stiffness under normal cutting conditions but retracts the cutting tool from the cut when a preset threshold force level is exceeded. The system has been did on a full-sized NC machining center and its performance has been measured.
