摘要： In a shape measuring apparatus for measuring the roughness and/or contour of a surface of a workpiece by sliding a sensing pin on a tip end side of an arm on the workpiece, the arm is provided with an engagement mechanism that makes a sensing pin side of the arm removable to a base end side of the arm. The engagement mechanism has two engagement surfaces which face each other and attract each other by a magnetic force. One of the engagement surfaces includes a linear first groove that is in parallel to an axis of the arm and another engagement part that is different from the first groove, and the other of the engagement surfaces includes a first fitting pin that is positioned to be fitted into the first groove and a second fitting pin that is fitted into the other engagement part.

摘要： A sensor is placed on a plate lowered into the hollow of the shaft and guided by taut wires between a lower attachment device and an upper motorized winder. The deformations, responsible for measurement errors and caused either by static deformations, produced by the weight or poor construction of the apparatus, or by vibrations, are to a large extent eliminated.

摘要： A gear measurement method and a gear measurement apparatus capable of evaluating meshing and fitting of a gear are provided. A measurement method for a gear includes a measurement step of measuring an actual movement locus of a ball that is moved along a tooth groove of the gear as a shape evaluation index for the gear. In the case of a VGR rack, tooth surfaces of rack teeth are constituted of curved surfaces. Thus, a reference pin for use in OPD cannot be disposed so as to be in line contact with the tooth surfaces, and the rack teeth cannot be measured. However, the ball can be disposed so as to be in point contact with the tooth surfaces, which enables a measurement of the rack teeth.

摘要： Aircraft engine rotors traditionally have low coaxiality after assembly. This is solved by the methods and devices described herein, having advantages that the rotors have high coaxiality after assembly, reduced vibration, easy installation, high flexibility, and improved engine performance. A measurement method and device use an air flotation rotary shaft system determining a rotary reference. An induction synchronizer determines angular positioning of a turntable. Using a four probe measurement device, a radial error of a rotor radial assembly surface and an inclination error of an axial mounting surface are extracted and an influence weight value of the rotor on the coaxiality of assembled rotors is obtained. All rotors required for assembly are measured and an influence weight value of each on the coaxiality of the assembled rotors is obtained. Vector optimization is performed on the weight value of each rotor and an assembly angle of each rotor is obtained.

摘要： A method for measuring a deflection amount of a columnar structure includes the following steps. The method includes placing a longitudinal direction of a columnar structure in a direction parallel to a ground to place the columnar structure on a support member that supports the columnar structure such that the columnar structure is rotatable around an axis in the longitudinal direction; determining that the columnar structure placed has stopped rotating under its own weight around the axis; and measuring, after the stop of the rotation is determined, measuring a distance in a vertical direction between a straight line connecting both ends in the longitudinal direction of the columnar structure and a curved line along a shape in the longitudinal direction of the columnar structure.

摘要： This invention relates to a method for measuring a feature of an object that comprises obtaining a representation of at least the feature on the object by acquiring multiple data points via surface measurement of at least the feature. A model substantially replicating at least the feature of the object is fitted to the representation. The model comprises parameters defining at least two independently alterable portions that are linked at a common point. The fitting comprises changing the form of the model by altering at least one of the at least two independently alterable portions. The method also comprises obtaining information regarding at least the feature from the fitted model.

摘要： A method for determining a surface profile change in a filling compound in a recess includes determining a first surface profile of a surface of the filling compound across the recess at an initial temperature; cooling or heating the recess comprising the filling compound to a predetermined measurement temperature; determining a second surface profile of the surface of the filling compound across the recess at the measurement temperature; and comparing the second surface profile with the first surface profile to determine the surface profile change.
