Abstract:
A coordinate measuring machine revises its original measurement trajectory, prior to completing its measurement of a work piece, upon detecting misalignment between its original measurement trajectory and the orientation of the work piece.
Abstract:
A probe clip allows easy and accurate placement of the probe clip onto a coordinate measuring machine ("CMM"). Moreover various probe clips are configured to movably and adjustably secure an optical probe to the CMM. To that end, the probe clip may have a probe seat, for holding the probe, movably coupled to a clamp segment by an adjustable joint. The clamp segment movably couples the probe seat to a probe platform on the CMM.
Abstract:
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.
Abstract:
A method and apparatus for measuring an object using a coordinate measuring machine comprising projecting temporary markers onto a portion of the coordinate measuring machine and thereby locating the object using logic associated with the coordinate measurement machine. In response to locating the object, a controller directs a measuring device of the coordinate measuring machine to measure the object.
Abstract:
An apparatus for producing an object has an additive printing device 20 for producing a three-dimensional object in a plurality of layers, and a measuring device 22 for measuring the object during the printing process. The apparatus also has a controller operatively coupled with the measuring device. The controller is configured to control the measuring device to measure the object at one or more prescribed points in the printing process (i.e., before the object is manufactured).
Abstract:
A coordinate measuring machine has 1) an anchor beam with a top end and a bottom end, 2) at least one support beam having a top end and a bottom end, and 3) a cross-beam supported on the top ends of both the anchor beam and the at least one support beam. In addition, the coordinate measuring machine also has 4) a base supporting the bottom ends of the anchor beam and the at least one support beam. At least one of the at least one support beams has a first spring and a second spring. In preferred embodiments, the first spring is adapted to allow movement and is spaced from the second spring in a direction that is generally parallel with the longitudinal axis of the cross-beam.
Abstract:
An articulated arm can include a plurality of articulated arm members, a probe, a receiving portion at a distal end comprising a threaded portion, and a base at a proximal end. A base plate can kinematically mount on the receiving portion and have a hole positioned such that the probe passes through the hole. The base plate can also couple to a laser and an optical sensor located on opposite sides of the hole. A nut can threadably mount to the threaded portion of the receiving portion. Further, a wave spring can mount on the receiving portion between the nut and the base plate. Thus, movement of the nut along the receiving portion can cause the wave spring to urge the base plate against the articulated arm to secure the kinematic mount. The wave spring can then mechanically isolate the base plate from the articulated arm.
Abstract:
A coordinate measuring machine compensates for hysteresis error caused by friction at the non-driven end of the bridge. The bridge may have a single drive and/or a single scale. The methods, systems, and apparatuses compensate for errors in the x-direction and/or errors in the y- direction caused by rotation of the bridge. Some embodiments compensate for hysteresis errors in the x-direction caused by a vertically-movable ram.
Abstract:
Embodiments provide measurement systems having a coordinate measuring machine, a workpiece storage apparatus, and a robot for delivering workpieces from the workpiece storage apparatus to the coordinate measuring machine, and methods for orienting and operating such systems. Illustrative embodiments employ a reference geometry tool on the robotic arm, and kinematic locators on the coordinate measuring machine and/ or on the workpiece storage apparatus to define a coordinate system common to the coordinate measuring machine, the workpiece storage apparatus, and the robot.
