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.
