  • Patent number: 9207076
    Abstract: In a method for determining ricochet vectors of a probe of a coordinate measuring machine (CMM) using a computing device, the computing device sets an approach distance between the probe and a manufactured object. Coordinates of a center of the probe and an initial vector of the probe for each measurement point of the manufactured object are obtained when the probe is manually operated to measure the manufactured object. A measurement element of the manufactured object is fit according to all measurement points of the manufactured object. For each measurement point, an approach point of the manufactured object is calculated, a position relation between the approach point and the measurement element of the manufactured object is determined, and a ricochet vector of the probe is calculated according to the position relation.

  • Patent number: 8913125
    Abstract: In a method for regulating coordinates of a probe measurement system using an electronic device, the method determines a first center of a reference object using a probe measurement system, and a second center of the reference object using an image measurement system. The method further determines regulation values between the probe measurement system and the image measurement system by calculating difference values between coordinates of the first center and the second center of the reference object, and stores the regulation values in a storage device of the electronic device.

  • Publication number: 20140257733
    Abstract: In a method for checking installation positions of probes of a star prober using a coordinate measurement device, the star prober is fixed vertically on a platform and supported by a movable arm, and a standard ball placed on the platform. The first probe measures a first point on a top surface of the standard ball, and the second probe measures a second point on the top surface of the standard ball. An X-Y coordinate system based on the first and second points is established, and a value of any deviation angle between the first probe and the second probe is calculated based on the X-Y coordinate system. The information is displayed for indicating whether the installations of the first and second probes are precise or not according to any deviation value, and the respective installations of the other individual probes are checked against the X-Y coordinate system.

  • Patent number: 8805674
    Abstract: An electronic device connected to a measurement machine is installed with an image measurement program. The electronic device records detailed information in relation to a new language file added to a template file provided by the image measurement program, and creates one or more executable files for the image measurement program based on the template file. When the image measurement program is started, the electronic device adds the new language to a language selection menu of a user interface of the image measurement program by executing the one or more executable files, displays all languages available to the image measurement program under the language selection menu of the user interface, and after selection and displays all information in a user-selected language.

  • Publication number: 20130139046
    Abstract: A method generates a measurement report of an object using a computing device. The method obtains measurement data of feature elements of the object, processes the measurement data to obtain output data, and outputs the measurement data of the output data to the measurement report according to a report output way corresponding to a report format, wherein the report format is received from a selection of the user. The measurement report is stored in a storage device of the computing device, or displayed on a display device that is connected to the computing device.

  • Publication number: 20130124135
    Abstract: In a computing device, computerized method, and a non-transitory storage medium, correction data of a probe holder is read. The probe holder comprises one or more slots that houses all available probes and is placed on the coordinate measuring machine. The correction data comprises coordinates of the slots. A coordinate of one of the slots is obtained from the correction data. A Z-axis of the coordinate measuring machine moves to a position that corresponds to the extracted coordinates, to detach a probe which is currently installed on the Z-axis and to place the detached probe into the slot, and/or to pick up and install another probe which is currently housed in the slot onto the Z-axis.
