  • Patent number: 10416655
    Abstract: Machining methods for machine tools where a workpiece can be manually moved by an operator or by automatic operation. A drawing file is displayed on a screen and machining is performed. An evaluation is performed to determine if the processed points of the workpiece match the desired processing coordinates within a tolerance range. Accordingly, the system is selectively activated to prevent processing at incorrect processing points or deviating from the tolerance range of the desired processing points. Processing yield rate is improved and all processing points are monitored by the system and displayed on a drawing file screen.

  • Patent number: 10259070
    Abstract: A plasma cutting system for measuring or monitoring the voltage between a plasma torch and the material being cut to determine a voltage or voltage signature and comparing that measurement against predetermined values to indicate that an initial pierce of the material is complete, and based on the measurement, moving the torch or the material to a different location for additional cutting. The system further provides a Fix Drawing Tool, which will automatically detect and fix gaps or overlaps in a drawing that are very difficult to find visually. These gaps and overlaps become a problem when trying to make a proper toolpath because a CAM program requires a clean, closed shape. The system also provides a Dynamic Corner Looping system, which automatically adjusts with the feed-rate and accelerations of the toolpath and plasma machine, eliminates unwanted dross, sharpens corners and minimizes material loss. A pendant tethering system is also disclosed for managing control of a CNC machine remotely.

  • Patent number: 9651356
    Abstract: Exemplary inventive practice provides for evaluation of a substantially cylindrical object in terms of its conformity to dimensional tolerance standards designated for that object, such as involving runout tolerancing or profile tolerancing. Distances to the curved axial-longitudinal surface of the object are measured by sensors (e.g., linear variable differential transformers) at various axial-rotational orientations of the object. A computer converts the sensory measurements (e.g., represented as voltage signals) to linear measurements (e.g., defined in inches or centimeters), compares the linear measurements to pertinent dimensional tolerance standards stored in memory, and renders a “pass-or-fail” decision regarding acceptability of the object. Failure of the object is implied by nonconformity in any respect of its linear measurements to its dimensional tolerance standards.

  • Patent number: 8700203
    Abstract: Four basic measurements are performed when calibrating a spherical measurement probe fastened to a tool spindle having a fixed longitudinal position along the spindle axis. Moving the measurement probe transversely towards the calibration sphere yields a basic position of the tool spindle relative to an element with an attached calibration sphere, when measurement probe touches the calibration sphere. The measurement probe is rotated about the spindle axis from one basic measurement to the next by the same angle, whereas the orientation of the calibration sphere is maintained for all four basic measurements. Based on the basic positions, a reference position of the tool spindle relative to the element, at which the tool spindle is located above the calibration sphere and the spindle axis goes through a central point of the calibration sphere, is determined and taken into account in further calibration of the measurement probe.

  • Patent number: 8600523
    Abstract: In a method for controlling an operation of a coordinate measuring device, at least one operational parameter is determined. One value of the operational parameter is allocated to a plurality of components. A sequence for determining the operational parameter is provided for the majority of the components. The method for determining the operational parameter in the predetermined sequence for each component is now described. It starts with the component that is first in the sequence: i) if the value of the operational parameter is allocated to the component, the value is adopted as a value of the operational parameter that is available for the operation, ii) if no value of the operational parameter is allocated to the components, one available value of the operational parameter that was available until then still remains available, iii) if another component is provided in the sequence, the method is carried out with the component.

  • Publication number: 20130151001
    Abstract: Four basic measurements are performed when calibrating a spherical measurement probe fastened to a tool spindle having a fixed longitudinal position along the spindle axis. Moving the measurement probe transversely towards the calibration sphere yields a basic position of the tool spindle relative to an element with an attached calibration sphere, when measurement probe touches the calibration sphere. The measurement probe is rotated about the spindle axis from one basic measurement to the next by the same angle, whereas the orientation of the calibration sphere is maintained for all four basic measurements. Based on the basic positions, a reference position of the tool spindle relative to the element, at which the tool spindle is located above the calibration sphere and the spindle axis goes through a central point of the calibration sphere, is determined and taken into account in further calibration of the measurement probe.

  • Patent number: RE45391
    Abstract: A drilling machine drills at a multiplicity of target locations on a component. Two robots, calibrated with calibration data, move the component in a 6-D coordinate system. A metrology system ascertains the position of the component relative to the drilling machine. The movement of the robots is effected by commands generated by off-line programming. The component is moved relative to the drilling machine to a target position, ready for drilling, by a closed-loop process in which the differences in position between the expected position (the target position) and the actual position (as viewed by the metrology system) are corrected.
