摘要： Gear testing apparatus has a tooth flank probe or feeler displaceable in a spatial co-ordinate system by being mounted on a series of three support members each movable in a different direction. Scales monitoring the member movements feed member position data to a computer in which a movement programme is stored. In one arrangement, the computer programme controls movements of all three members and deviations in tooth flank form cause deflections of the feeler that are evaluated by the computer. In another arrangement, two of the members are driven by the programme data and the third member is displaced by biassing means to hold the feeler against a tooth flank, the computer comparing said displacements with reference values to evaluate deviations in the tooth flank form.

摘要： A method and an apparatus for determining a plurality of spatial coordinates on a measurement object using a working head having an image sensor for recording images of the measurement object. A first image of a first feature of the object with the working head in a first working position is recorded. First spatial coordinates representing a spatial position of the first feature are determined using first position information of the working head supplied by an encoder arrangement. The working head is then moved relative to the object to a second working position, where a second image of the object is recorded. Using the first and the second images, second position information which represents a spatial offset of the working head relative to the object is determined. Spatial coordinates for a second feature of the measurement object are determined on the basis of the second position information.

摘要： A method of building up a measurement data set for a surface of an object using an analog measurement probe mounted on a machine tool apparatus which obtains scanned measurement data of the surface over a plurality of offset traverses. Subsequent traverses are offset from previous traverses such that over a series of traverses the analog probe's surface detecting region progresses i) laterally across the object, and/or ii) away from or towards the object. The course of relative motion for at least one subsequent traverse is generated and/or updated based on data obtained during at least one previous traverse.

摘要： There is provided a method for controlling a shape measuring apparatus which can achieve both trajectory correcting capability and control stability. A stylus tip is moved along a scanning path while controlling the stylus tip so as to keep an amount of deflection of a probe to a workpiece to be a reference amount of deflection. A movement instruction for the probe is generated according to a combined velocity vector V represented by the following expression: combined velocity vector V=Gf·Vf+Ge·Ve+Gc·Vc2, where Vf is a path velocity vector to move the probe along the scanning path, Ve is a deflection correcting vector to keep the amount of deflection of the probe to the workpiece to be the reference amount of deflection, Vc2 is a second trajectory correcting vector represented by (Vc1·q)q, Vc1 is a first trajectory correcting vector to correct a position of the probe so that the stylus tip heads to the scanning path, and q is a trajectory correcting direction vector given by a vector product of a normal line of a surface of the workpiece and the path velocity vector Vf.

摘要： A system for mapping a tissue surface includes a probe for mapping a tissue surface, a localization system to measure a location data point indicative of the probe's location, a memory in which to store the location data point, a servo mechanism to move the probe along at least a portion of the tissue surface, a controller to move the probe to a plurality of locations and to record in the memory a plurality of location data points, and a contact-sensing processor to analyze the plurality of location data points and to identify a subset thereof on the tissue surface. A modeling processor generates a model of the tissue surface using the subset of location data points. The contact-sensing processor utilizes probe velocity, or a rate of change in the distance moved by the probe, to determine contact between the probe and the tissue surface.
