Abstract

A standard (10) for calibrating a coordinate measuring machine has a base (12) with a permanent calibration structure (14). The calibration structure (14) has a first component (15). The first assembly (15) is designed in such a way that the three axes (18) of the projection (20) of the first assembly (15) onto the plane intersect at a common point (16) respectively pass through the first zone of the same design Paragraph (22). These first sections ( 22 ) are each delimited on one side by a common point ( 16 ). These first segments ( 22 ) of identical design each have n zones ( 24 ). Immediately adjacent regions ( 24 ) differ in optical characteristics. n is greater than or equal to 3.

Description

technical field [0001] The present invention relates to a standard (Normal) for calibrating a coordinate measuring machine. The standard has a base with a permanent calibration structure. The calibration structure has a first component. The first component is designed in such a way that the three axes of the projection of the first component onto the plane, which intersect at a common point, each pass through a first section of the same design. These first sections are each bounded on one side by a common point. These first sections of the same design each have n zones. Immediately adjacent zones differ by optical characteristics.
