US 2024/0302820 A1 · NUMERICAL CONTROL DEVICE

Abstract

A numerical control device includes: a first control unit which rotates a workpiece about a rotation axis of the workpiece; a second control unit which rotates a rotary tool at a rotation speed with a constant ratio with respect to the rotation speed of the workpiece about the rotation axis, of the rotary tool, parallel to the rotation axis of the workpiece; and a third control unit which controls the relative positions of the rotation axis of the rotary tool and the center axis of a polygon so that the positional relationship between the rotation axis of the rotary tool and the center axis of the polygon is fixed, and the center axis of the polygon passes through a predetermined position of the workpiece and is parallel to the rotation axis of the workpiece.

Dependent claims

A numerical controller comprising:

a first control unit configured to rotate a workpiece around a rotation axis of the workpiece;
a second control unit configured to rotate a rotary tool around a rotation axis of the rotary tool at a rotation speed of a constant ratio with respect to a rotation speed of the workpiece, the rotation axis of the rotary tool being parallel to the rotation axis of the workpiece;
and
a third control unit configured to control a relative position between the rotation axis of the rotary tool and a center axis of a polygon so that a positional relationship between the center axis of the polygon and the rotation axis of the rotary tool is kept constant, the center axis of the polygon being parallel to the rotation axis of the workpiece and passing through a predetermined position of the workpiece.
