A method of calibrating an x-ray computed tomography machine provides an x-ray computed tomography machine having calibration settings, and uses the x-ray computed tomography machine to produce a gauge reconstruction. The gauge has a first base supporting two or more objects, and a second base supporting two or more objects. The first base and the second base form a perpendicular configuration, and each of the plurality of objects is secured on at least one of the first base and the second base. Each of the objects has a center, and the distance between the centers of each object is known. The method then measures the distance between at least two objects to produce measured center distance values, compares the measured center distance values against the known center distance values, and uses the comparison to determine if there is a distance error in the gauge reconstruction.

A coordinate measuring machine has a base for supporting an object, a movable assembly having a probe for measuring the object, and a rail movably guiding the movable assembly along its length. The rail includes carbon fiber and has a rail CTE. The coordinate measuring machine also has an air bearing member circumscribing the rail and fixedly coupled with the movable assembly. The air bearing member has a member CTE, which is about equal to the rail engineered CTE.

A method of producing a three-dimensional object from an extrusion of material forms uses a movable portion of an additive extrusion printing device to form at least one line of material (line of material). The printing device preferably extrudes the material as a function of a nominal model having a specification of the object. The method also measures, using a coordinate measuring machine, at least one dimension of the line of material after starting to extrude the line of material. During or after measuring, the method checks, using a checker operatively coupled with the coordinate measuring machine, the dimensional accuracy of at least one dimension of the line of material by comparing the at least one dimension with at least one specification of the nominal model of the object.

An apparatus for calibrating an x-ray computed tomography device has a plurality of objects formed from a material that is visible to x-rays. The plurality of objects are configured to receive x-rays without changing shape, and have substantially the same shape. The objects each have an object attenuation value to x-rays and a center point such that they are symmetrically shaped relative to their respective center points. The apparatus also has a base at least in part fixedly supporting the plurality of objects so that each of the plurality of objects contacts at least one of the other objects. Like other physical objects, such as the objects, the base has a base attenuation value to x-rays, and that value is greater than the base attenuation value. The center points of the plurality of objects together form a three-dimensional volume.

An articulating probe for use with a coordinate measuring machine comprises an attachment portion, a measuring portion, and at least one articulating joint. The attachment portion can be configured for attachment to a coordinate measuring machine. The measuring portion can be configured to contact an object, to be measured by the coordinate measuring machine. The at least one articulating joint can be configured to allow rotation between the attachment portion and the measuring portion. Further, the articulating joint can comprise an angular sensor configured to measure an angle of the joint.


A method of measuring an object uses a coordinate measuring machine, which is positioned within an environment (e.g., a clean room). The method receives sensing information relating to the coordinate measuring machine, the environment, or both the coordinate measuring machine and the environment. Next, the method controls the coordinate measuring machine to perform, based on the sensing information, a specified mechanical action.

A multi-mode coordinate measuring machine system can be configured to measure coordinates in a variety of ways with a certain set of components. For example, an articulated arm coordinate measuring machine can measure coordinates on an object using a contact probe or a non-contact measuring device mounted on the articulated arm. Then, a user can remove the non-contact measuring device from the articulated arm coordinate measuring machine, and take additional measurements of the object that can be aligned with measurements taken by the articulated arm and devices attached thereto.

In some embodiments, an articulated arm coordinate measurement machine can include a plurality of transfer members and a plurality of articulation members connecting the plurality of transfer members to each other to measure an angle between the transfer members. The machine can additionally include at least one coordinate acquisition member positioned at an end of the articulated arm. Further, the machine can include a harness connected to at least one of the group consisting of the transfer members and the articulation members to support at least a portion of the weight of the transfer members and the articulation members. The harness can also be configured to mount to a human.

A method and apparatus for measuring an object using a CMM receives nominal geometry data relating to the object, and produces a set-up path based on the received nominal geometry data. The method also conducts a set-up measurement of the object using a CMM probe. The CMM probe conducts the set-up measurement by following the set-up path, and the set-up measurement of the object produces scan path information. The method generates a scan path using the scan path information, and controls the CMM probe to conduct a fine measurement of the object by causing the CMM probe to move along the generated scan path.
