A system and methods for transprojection of geometry data acquired by a coordinate measuring machine (CMM). The CMM acquires geometry data corresponding to 3D coordinate measurements collected by a measuring probe that are transformed into scaled 2D data that is transprojected upon various digital object image views captured by a camera. The transprojection process can utilize stored image and coordinate information or perform live transprojection viewing capabilities in both still image and video modes.

A novel adjustable hand grip device for use with a three dimensional coordinate measurement system provides an ergnomically formed pistol grip rotatably positioned on a manually manipulated multijointed measuring arm allowing a plurality of angular positions convenient to an operator. The adjustable hand grip includes a clamp for releasably securing the device n a preselected position. An embodiment of the present invention includes a ball and detent device for releasably positioning the hand grip in a plurality of preselected positions. In yet another embodiment the hand grip device includes a swivel joint allowing rotation of the pistol grip relative to the clamp.

A method for scanning a surface of a workpiece 1 at a constant scanning speed /v_a/ using a scanning probe 2 mounted on a support 3 on a coordinate measuring machine (CMM) 4. The CMM contains a first set of drive means (6, 7, 8) to move the support according to three linear axis (x,y,z), and the support 3 contains a second set of drive means (14, 17) for actuating the movement of the scanning probe 2 with two degrees of freedom relative to said support 3. The method involves control means 33 coupled to the sets of drive means (6, 14, 17), and memory means for storing theoretical profiles and coordinates of the surface to scan.

The method also includes combining ultrasonic inspection (UT) capabilities and CMM capabilities to form an inspection probe. The inspection probe is installed on the CMM so that the inspection probe measures external boundaries of the machine component with the CMM capabilities and substantially simultaneously measures internal boundaries of the machine component with the UT capabilities.

A method for providing feedback to the operator of a portable coordinate measurement machine which comprises an articulated arm having jointed arm segments is presented. The method includes sensing deformation of a portion of the articulated arm when the arm is placed under a load, the deformation being an indication of the magnitude of the external force being applied to the arm, and providing feedback to the operator of the CMM in response to the sensed external forces.

A portable articulated arm coordinate measuring machine (AACMM) includes a manually positionable arm portion having opposed first and second ends, the arm portion including connected arm segments, each arm segment including at least one position transducer for producing a position signal, a measurement device attached to a first end of the AACMM, and an electronic circuit which receives the position signals from the transducers and provides data corresponding to a position of the measurement device. Implementing the portable AACMM includes identifying a source device from which data is received by determining a transmission path through which the data is transmitted, the source device removably attached to the first end of the AACMM, determining a data type of the data based upon identification of the source device, performing an action on the data responsive to the data type, and outputting results of performing the action to a destination device.

The encoder data bus is coupled to the arm portion and the electronic circuit, and the encoder data bus is configured to send the position signal to the electronic circuit. The first device data bus is coupled to the accessory device and the electronic circuit. The first device data bus is configured to operate simultaneously with and independently of the encoder data bus for sending accessory device data from the accessory device to the electronic circuit.

The present invention provides an apparatus and method for an adaptive machining and weld repair process useful for repairing airfoils, particularly damage to an airfoil leading edge and tip. The process first machines away damaged portions of an airfoil. Filler material is then added to the machined area through a process such as laser welding. At this point, the actual profile of the welded airfoil is measured using a Coordinate Measuring Machine. This data is then used to generate a “deformation” profile, an airfoil profile that approximates the ideal shape of the airfoil. The airfoil is then machined using the date of the deformation profile to produce that shape. The adaptive technology minimizes the amount of stock on material that needs to be removed by hand. The technique thereby significantly reduces costly manual processing.

A system and method for identifying defects in a workpiece are provided. The system includes a sensor for non-destructive testing. The system also includes a movable arm carrying the sensor and being pivotally attached to a base. The movable arm includes at least one pivotable joint between the base and the sensor, and is capable of being moved such that the sensor acquires data indicative of a workpiece as the sensor travels proximate to the workpiece. A data acquisition system is capable of communicating with the sensor to create an image of at least a portion of the workpiece based on the data acquired by the sensor.

A thermal deformation error compensation method for a coordinate measuring machine creates thermal deformation and geometric error data at different ambient temperatures including temperatures and machine kinematic parameters to obtain a thermal deformation and geometric error model, and inputs the model into central control unit of the coordinate measuring machine, and converts a 3D error compensation to obtain a thermal deformation and geometric error compensation model, and uses the thermal deformation and geometric error compensation model for performing compensations, so as to complete a thermal deformation and geometric error compensation of the coordinate measuring machine.
