Method and apparatus for vibration machining with two independent axes
First Claim
1. A vibration machining apparatus for use in machining a surface of a workpiece, comprising:
- a cutting tool to machine at least a portion of the workpiece;
a motion stage coupled to one of the cutting tool or the workpiece to move the cutting tool relative to the workpiece coupled to the motion stage such that the cutting tool follows a machining path on the surface of the workpiece, a tangent to the machining path and a normal to the surface of the workpiece defining a vibration plane;
a first vibrating unit coupled to one of the cutting tool or the workpiece to vibrate the one of the cutting tool or the workpiece coupled to the first vibrating unit along a first vibrational direction, the first vibrational direction being in the vibration plane or substantially in the vibration plane; and
a second vibrating unit coupled with one of the cutting tool or the workpiece to vibrate the one of the cutting tool or the workpiece coupled to the second vibrating unit along a second vibrational direction, the second vibrational direction being different from the first vibrational direction and in the vibration plane or substantially in the vibration plane.

Abstract
A vibration machining apparatus and method of use. The vibration machining apparatus includes a cutting tool and a motion stage coupled to one of the cutting tool or the workpiece to move the cutting tool relative to the workpiece. A tangent to a machine path and a normal to the surface of the workpiece define a vibration plane. The vibration machining apparatus further includes a first vibrating unit coupled to one of the cutting tool or the workpiece to vibrate it along a first vibrational direction, substantially in the vibration plane, and a second vibrating unit coupled with one of the cutting tool or the workpiece to vibrate the one of the cutting tool or the workpiece coupled to the second vibrating unit along a second vibrational direction, different from the first direction and substantially in the vibration plane.

15. A method of machining at least a portion of a workpiece using vibration machining apparatus, the method comprising the steps of:
-
a) moving a cutting tool relative to the workpiece such that the cutting tool follows a machining path on the surface of the workpiece, a tangent to the machine path and a normal to the surface of the workpiece defining a vibration plane;
b) vibrating one of the cutting tool or the workpiece coupled to a first vibrating unit along a first vibrational direction, the first vibrational direction being in the vibration plane or substantially in the vibration plane; and
c) vibrating one of the cutting tool or the workpiece coupled to the second vibrating unit along a second vibrational direction, the second vibrational direction being different from the first vibrational direction and in the vibration plane or substantially in the vibration plane. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
