Automatic tool position compensating system for a numerically controlled machine tool
Abstract
Abstract IN A NUMERICALLY CONTROLLED MACHINE TOOL HAVING A TOOL SUPPORT SLIDE, A MULTIPLE TOOL TURRET, A CONTROLLER AND A MEASURING ELEMENT, A RING GAUGE IS MOUNTED ON THE MAIN SPINDLE OF SAID MACHINE TOOL COAXIALLY THERETO SO THAT THE DEVIATIONS OF SAID MAIN SPINDLE IN X AND Z DIRECTIONS MAY BE ACCURATELY MEASURED AND COMPENSATED FOR. TO DO THIS, THE MEASURING ELEMENT UTILIZES THE OUTER PERIPHERAL SURFACE AND THE INWARDLY FACING END SURFACE OF SAID RING GAUGE AS THE REFERENCE OR STANDARD POSITIONS IN X AND Z DIRECTIONS, RESPECTIVELY. THE DEVIATIONS ARE COMPENSATED IN THE SUCCEEDING CUTTING PROCESS FOR SHIFTING THE TOOLS RESPECTIVELY, EACH IN ACCORDANCE WITH THE ERROR DETECTED, BY PARALLEL SHIFTING OF THE CO-ORDINATE AXIS OF THE TOOLS. ALTERNATELY, THE AXES MAY BE SHIFTED ANGULARLY, OR THE PARALLEL SHIFT MAY BE COMBINED WITH THE ANGULAR SHIFT OF THE CO-ORDINATE AXES.
