Abstract
A chuck jaw includes a foot portion configured to be mounted on a chuck body, a jaw body configured to hold a workpiece, and a metal layer provided on the jaw body such that the jaw body is configured to hold the workpiece via the metal layer. The metal layer includes a first metal material that has a thermal conductivity lower than a thermal conductivity of a second metal material which the jaw body includes.

A method of fabricating a chuck jaw, the method comprising:
- mounting, on a chuck body rotatable about a first axis, a foot portion of a first block comprising the foot portion and a jaw body;
- and
- providing a metal layer on the jaw body in a state where the foot portion is mounted on the chuck body such that the jaw body is configured to hold a workpiece via the metal layer, the metal layer comprising a first metal material that has a thermal conductivity lower than a thermal conductivity of a second metal material that the jaw body comprises.
A method of machining a workpiece, the method comprising:
- fabricating a first chuck jaw, the fabricating comprising:
- mounting, on a chuck body rotatable about a first axis, a foot portion of a first block comprising the foot portion and a jaw body;
- and
- providing a metal layer on the jaw body in a state where the foot portion is mounted on the chuck body, the metal layer comprising a first metal material that has a thermal conductivity lower than a thermal conductivity of a second metal material which the jaw body comprises;
- mounting the workpiece on a plurality of chuck jaws comprising the first chuck jaw;
- and
- machining the workpiece, the machining comprising:
- providing a third material on the workpiece using an additive manufacturing apparatus in a state where the metal layer of the first chuck jaw is in contact with the workpiece.
