ABSTRACT:
A spindle 51 capable of controlling quantitatively the rotational angle around the center axial line itself is mounted with a turning tool 50; the spindle 51 and a workpiece are allowed to be relatively dislocated by an axial control along at least a plane perpendicular to the rotation axial line of the spindle 51 in such a manner that the relative movement locus L of the spindle center Cs to the workpiece conforms to a geometry to be machined and a required front rake angle .beta. is set, thereby allowing a mutual interpolation motion between the spindle and the workpiece to be performed; and the rotational angle of the spindle 51 is synchronously controlled with a required interrelation to the above-mentioned axial control, whereby the direction of the cutting edge of the turning tool 50 to the machined face of the workpiece is kept at a required direction at the full rotational angle position of the spindle 50 with the required front rake angle .beta., and the direction of the cutting edge of the turning tool 50 to the machined face of the workpiece W is kept at a required direction, and then the workpiece W is machined into a geometry determined by the interpolation locus L due to the above-mentioned mutual interpolation motion.
