  • Publication number: 20160077515
    Abstract: A computer numerical control (CNC) machining center is provided. The CNC machining center includes a spindle that receives a cutting tool. A work surface is operably arranged adjacent the spindle. A non-contact three-dimensional (3D) measurement device is operably coupled to the tool mount, the 3D measurement device including a projector and at least one device camera, the at least one camera being arranged to receive light from the light source that is reflected off of a surface. A plurality of targets is provided with at least one of the targets coupled to the 3D measurement device. At least two photogrammetry cameras are provided having a orientation and a field of view to acquire images of the targets. A controller is coupled for communication to the 3D measurement device and the at least two cameras, the controller determining the position of the 3D measurement device within the machining center during operation.

  • Publication number: 20160016274
    Abstract: A computer numerical control (CNC) machining center is provided. The CNC machining center includes a spindle configured to receive a cutting tool having a tool mount. A tool magazine is provided having a plurality of holders, each holder configured to receive a tool having the tool mount. A primary induction power supply operably coupled to the spindle. A non-contact three-dimensional (3D) measurement device having the tool mount is provided. The 3D measurement device is movable between one of the tool magazine holders and the spindle. The 3D measurement device having a secondary induction power supply configured to generate electrical power to operate the 3D measurement device when the 3D measurement device is coupled to the spindle.

  • Patent number: 9228816
    Abstract: A method of determining a mathematical transformation to place three-dimensional (3D) coordinates of points measured by an articulated arm coordinate measurement machine (AACMM) and 3D points measured by a scanner in a common coordinate system is provided. The method including providing the 3D scanner and the AACMM having a probe. The scanner and AACMM each have a local frame of reference. Three non-collinear targets are measured with the probe and then with the scanner. 3D probe reference coordinates and 3D scanner reference coordinates are determined based on the measurement of the targets by the AACMM and scanner. The mathematical transformation is determined based at least in part on the 3D probe reference coordinates and the 3D scanner reference coordinates, the mathematical transformation characterized at least in part by a collection of parameters.

  • Publication number: 20150178412
    Abstract: A system and method of determining 3D coordinates of an object is provided. The method includes determining a first set of 3D coordinates for a plurality of points on the object with a structured light scanner. An inspection plan is determined for the object, which includes features to be inspected with a remote probe. The points are mapped onto a CAD model. The features are identified on the plurality of points mapped onto a CAD model. A visible light is projected with the scanner proximate a first feature of the features. A sensor is contacted on the remote probe to at least one first point on the first feature on the object. A first position and orientation of the remote probe are determined with the scanner. A second set of 3D coordinates of the at least one first point are determined on the first feature on the object.
