PURPOSE:To provide highly precise surface machining by machining a surface only twice. After a work is machined once, it is turned by 90 degrees, and flatness of the machined surface is observed. The surface is machined once more depending on an observed flatness. CONSTITUTION:A work 16 is machined by a cutting tool 9 after actuating a drive machanism 6 to rotate a spindle 7, and feeding a feeding table 2. A drive mechanism 15 is actuated, the work 16 is turned by 90 degrees, and flatness of the machined surface is measured by a detector 1. Then an angle of the spindle 7 is modified depending on a result of the detector, and the surface of the work 16 is machined once more by feeding the cutting tool 9 same as in the previous first machining process, thus obtaining highly precise work surface. |
