TWO-DIMENSIONAL METROLOGICAL CALIBRATION STANDARD

摘要

A two dimensional metrological calibration standard includes a plurality of calibration cylinders each having a diameter and a plurality of calibration gauge blocks each having a length, each calibration gauge block being interposed between two of the calibration cylinders, such that end faces thereof are in contact with the walls of adjacent calibration cylinders, the calibration cylinders and calibration gauge blocks as a group are fastened to a flat plate and conjointly form a triangle. Bearing and alignment rulers ensure alignment of the calibration gauge blocks between the calibration cylinders, by contact with the calibration gauge blocks and/or the calibration cylinders, and are fastened to the plate.
