    摘要： A method for providing dynamic state information for a coordinate measuring machine that includes a base, a probe head, a machine structure with structural components linking the probe head to the base and a drive mechanism that moves the probe head relative to the base. A dynamic model is defined with actual state variables related to physical properties representing an actual state of the coordinate measuring machine. The actual state is derived by a calculation based on the dynamic model. A filtering process using the dynamic model includes deriving prediction variables based on the state variables that describe an expected proximate state of the coordinate measuring machine, measuring at least one of the state variables and determining observables, deriving successive state variables by comparing the prediction variables with the observables and updating the dynamic model using the successive state variables as the actual state variables.

    摘要： There is provided a method for controlling a shape measuring apparatus which continues to perform nominal scanning measurement to a workpiece having a slightly large deviation from a design data. A scanning path to move a stylus tip is calculated based on design data of a workpiece. The stylus tip is moved along the scanning path. It is monitored whether a distance between the scanning path and an actual workpiece is excessive. When the distance between the scanning path and the actual workpiece is excessive, a trajectory difference error is generated. When the trajectory difference error is generated, geometric correction is performed to the design data so that the design data approaches to the actual workpiece. Scanning measurement is performed based on the design data after the geometric correction.

    摘要： An off-line graphical user interface (GUI) system and method provide for input control of a three-dimensional coordinate measuring machine (CMM) using the CMM's probe. A GUI image presents a plurality of control operation icons associated with the CMM. A controller uses the CMM to locate the GUI image in a coordinate system of the CMM. The controller defines coordinates of the control operation icons and references the coordinates to the coordinate system of the CMM. The controller also defines a function activation zone associated with each of the control operation icons. Each function activation zone defines criteria relating movement of the CMM's probe therein to the operational function of the CMM associated with one of the control operation icons corresponding thereto. Satisfaction of the criteria causes the operational function of the CMM to be carried out by the CMM.

    摘要： A method and apparatus for controlling or programming a measurement path for a probe mounted on a coordinate positioning apparatus (e.g. an articulating probe head mounted on a CMM) which enables both the position of the probe tip and the orientation of the probe to be varied. In a first mode, the position of the probe tip is adjusted. In a second mode the orientation of the probe is adjusted, while keeping the location of the probe tip unchanged. This may be achieved either online on the coordinate positioning apparatus or offline in software.
