A method and system for measuring a turbine shape is provided in which an appropriate measurement accuracy can be achieved that is sufficient to prevent a failure to recognize features of shape of a measurement object, with extension of a measurement time suppressed. In a turbine including casings, recesses and protrusions on flange surfaces of the casings are measured at measurement intervals M set on the basis of the entire length L of flange portions in an axial direction, the number of bolts N joining the flange portions, and intervals between the bolts in the axial direction of the flange portions.

A roundness measurement device provides a rotation table on a base and measures roundness of a measured object placed on the rotation table while rotating the rotation table, and includes a detecting main body, a detecting device driving mechanism, a stylus, a contact member, and a control device. The detecting device driving mechanism displaces the detecting device main body with respect to the base. The stylus has a base end rotatably supported on the detecting device main body and can change an angle position with respect to the detecting device main body using an external force. The contact member is provided at a position where the stylus comes in contact due to displacement of the detecting device main body by the detecting device driving mechanism. The control device controls driving of the detecting device driving mechanism.

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.

Applicant has disclosed a chamfer gage with interchangeable anvil assemblies which can measure the diameter of chamfered holes and the chamfer angle (up to 135°). In the preferred embodiment, the chamfer gage comprises: an indicator housing; a compression fitting, attached to the housing, for securing an indicator spindle for movement inside the housing; and an interchangeable anvil assembly, having an anvil body with a depressible anvil or plunger inside, which can be detachably connected to the indicator housing by a threaded thumb ring rotatably mounted on the housing. Another interchangeable anvil assembly can be swapped within thirty seconds to measure the chamfer of a different hole size.

Apparatus can comprise a probe movable in a direction along a probe axis that intersects a determination axis and a clamping pin can be movable along a clamping pin axis that intersects a product support area of a base. In some embodiments, methods of determining a height of an edge portion of a product can comprise aligning the edge portion of the product along a determination axis and clamping the product to a base at a clamping location of the product positioned over a product support area. Methods can further comprise extending a probe to contact a location of the edge portion of the product while the product is clamped to the base. Methods can further comprise determining a height of the edge portion of the product based on the position of the probe contacting the edge portion of the product.

A method for operating a surface measuring apparatus for measuring a surface of a workpiece. Method includes operating surface measuring apparatus having a probe that includes a probe arm that is deflectable by an angle about a swivel axis, and that on its end facing away from the swivel axis bears a probe element. Probe is movable relative to a base body of surface measuring apparatus along a linear axis. In method, a workpiece is contacted by moving the probe along the linear axis by use of the probe element, and after workpiece is contacted, probe arm is moved by a specified travel distance along the linear axis. The resulting angular deflection of the probe arm about the swivel axis is measured, and based on the specified travel distance and measured angular deflection of the probe arm, the probe arm is classified with regard to its length.
