    摘要: An apparatus, method, and system for determining the shape of a three dimensional object. In a preferred embodiment, the apparatus includes an array of sensors and elastic connections between the sensors within the array. When placed over a three dimensional object, the array of sensors deforms to conform to the surface topology of the three dimensional object. The sensors are connected to a data processor in which the data from the sensors is taken to construct a three-dimensional representation of the actual physical three dimensional object.

    摘要: A method and apparatus is provided for making impressions of edges and profiling the edges using a profiling machine. The apparatus allows the impressionable material used for forming the impression to be held in a fixed position while the impression of the edge is formed, and then allows the impression to be withdrawn in a manner that leaves the impression substantially unchanged and substantially true to the profile of the edge. The apparatus also comprises fittings to make the apparatus compatible with a profiling machine and allows the impression to be positioned in the profiling machine in substantially the same orientation every time an impression is taken.

    摘要: There is described a metrological instrument for measuring a characteristic of a surface of a workpicce, the instrument comprising a measurement unit and a user-interface unit separate from the measurement unit. The measurement unit has a sensor which follows a measurement path across a surface and means for deriving a signal indicative of a characteristic of the surface as the sensor follows the surface. The user-interface unit has means for providing a user with an indication of a surface characteristic measured by the sensor. The measurement unit and the user-interface unit have communication means for enabling remote communication of information relating to a measurement between the measurement and user-interface units. Preferably, the measurement unit and the user-interface unit can be connected together when not in use in a manner such that the sensor of the measurement unit is protected.

    摘要: An automatic production system includes an automatic washing device usable to wash off swarf left on a workpiece by an NC machine tool. The automatic washing device is used before measuring a portion of a workpiece using a three dimensional measuring device controlled by a measuring part program controlling the three dimensional measuring device. When automating an operation of the washing device, a washing program is produced based on the a measuring part program controlling the three dimensional measuring device to be able to efficiently wash a minimal area of the work piece encompassing the portion of the workpiece to be measured.

    摘要: A probe head 10 and a laser interferometric displacement meter 20 are provided. The probe head supports a probe 2 that is capable of contacting a workpiece 1, that is free to move in the direction of the workpiece, and drives the probe towards the workpiece. The displacement meter measures the displacement of the probe with a high accuracy without contact. The probe head 10 is also provided with a probe shaft 12 with steps 11a, 11b at intermediate portions thereof and air bearings 14a, 14b that support the probe shaft on each side of the steps. The air bearings have a high stiffness in the radial direction, and the probe shaft is made to float by using compressed air, thus the resistance of the shaft to sliding is reduced. In addition, another compressed air is supplied to the location of the step and produces a driving force in the direction of the workpiece due to the difference of cross sectional areas on each side of the step, that provides a very small load within a predetermined range. Thereby, the measuring pressure can be adjusted to a constant very small load without reducing the stiffness of the bearings of the probe, and the measuring pressures can be varied freely. Therefore, a sub-micron accuracy of about 0.1 &mgr;m can be obtained, and the equipment can be made compact and is easily applied to on-machine measurements.

    摘要: A system for part measurement and verification is disclosed. The system comprises a set of design criteria specifying a part and a fixture with gage blocks for positioning the part, where each of the gage blocks represents a known position. At least one probe is operable to measure the scalar values of the part and the gage blocks. A handheld information processor or computer is coupled to the probe for receiving the measurements and is operable to transform the measurements and compare those measurements to the design criteria to in order to verify the part. A method for part measurement and verification is disclosed. The method comprises eight steps. Step one calls for specifying the part with a set of design criteria. Step two requires storing the design criteria in a handheld information processor. Step three provides placing the part in a fixture with gage blocks at known locations. In step four, the method provides for configuring the handheld information processor to receive part measurements. The next step calls for measuring the part with a handheld probe to generate part measurements. Step six calls for receiving the generated part measurements in the handheld information processor. Step seven requires transforming the generated part measurements to a different reference frame. The last step calls for comparing the transformed part measurements to the design criteria in order to generate a part verification report.
