THREE-DIMENSION PROCESSING METHOD AND MACHINE BY BIAXIAL NUMERICAL CONTROL

PROBLEM TO BE SOLVED: To realize cutting work of a three-dimensional shape by interlocking rotation of a cutting object with longitudinal feed thereof whereas the cutting work of a three-dimensional shape conventionally requires a numerical control machine tool executing three or more axis control. SOLUTION: The cutting object 1 is fixed to a cutting object rotation shaft 2 and rotated. A rotating tool 12 longitudinally moved by being interlocked with the rotation through a reducer 4 spirally cut the cutting object, and can cut an arbitrarily-shaped curved surface by combining motion of a transverse shaft 8. By numerically controlling the two shafts for the rotation of the cutting object rotation shaft and the transverse feed, that is, both of a cutting object rotation motor 3 and a transverse motor 7, a three-dimensionally arbitrarily shaped object can be processed.
