摘要： PROBLEM TO BE SOLVED: To eliminate the need for severe alignment of a workpiece, and to machine the workpiece into a desired shape. SOLUTION: A servomotor 14 drives a first section 20 along a radius vector rotational direction. A second section 30 is movably supported along a radius vector direction, by the first section 20. A servomotor 23 drives the second section 30 along the radius vector direction. The second section 30 supports a tool 32 for machining the workpiece 50. A controller generates a measured data indicating a relation between a plurality of points of coordinates along the radius vector rotational direction on a reference face of the workpiece 50, and a radius-vector-directional distance up to a distance sensor 22, based on a distance signal from the distance sensor 22. determines a radius-vector-directional coordinate range of a step difference formed on the reference face, based on the measured data, generates a control data indicating a locus of the tool 32, based on the measured data and the coordinate range of the step difference, and numeral-controls the servomotors 14, 23, based on the control data. The controller uses selectively a plurality of offset values, based on the coordinate range of the step difference, when generating the control data. COPYRIGHT: (C)2010,JPO&INPIT
