Machine calibration artifact

摘要

A calibration artifact includes an elongated body made substantially entirely of ceramic material and having a direction of elongation. A plurality of measurement elements comprising the ceramic material are integrally formed with the elongated body, each measurement element comprising a first planar measurement surface facing in a first direction. The first planar measurement surface of each measurement element is parallel to the first planar measurement surface of each of the other measurement elements of the plurality of measurement elements. The calibration artifact may be a unitary step gauge formed with a single piece of ceramic material.

1. A calibration artifact comprising:
an elongated body having a direction of elongation; a plurality of support pieces configured to support measurement elements, each support piece having a first face disposed substantially parallel to at least one of the others of the first faces, and each first face being transverse to the direction of elongation of the elongated body; and a plurality of first measurement elements, each first measurement element comprising a first planar measurement surface facing in a first direction, and each first measurement element being supported on a first face of an associated one of the support pieces, wherein each first measurement surface is perpendicular to the direction of elongation of the body.
