Abstract: A method for calibrating parameters includes a measurement step that obtains measurement data by scanning a defined surface; a correction step that obtains corrected data by correcting the measurement data based on the parameters; a determination step that calculates a roundness of the corrected data and determines whether the calculated roundness is equal to or less than a predetermined value; and an adjustment step that increases or reduces at least one of the parameters when the roundness is determined to be greater than the predetermined value, and the correction step, the determination step, and the adjustment step are repeated until the roundness is determined to be equal to or less than the predetermined value.

Abstract: A threaded shaft measuring device includes a table that supports a threaded shaft to be measured, and that is capable of adjusting a rotation position about a perpendicular Z axis, adjusting a rotation position about an X axis that is horizontal and intersects with the Z axis, and adjusting a position in a Y axis direction that is horizontal and intersects with the X axis; and a stylus that performs scanning measurement of a surface of the threaded shaft. An adjustment jig capable of making contact with the threaded shaft and an elevator that brings the adjustment jig into contact with the threaded shaft are installed on the table. The adjustment jig includes an abutting bottom surface; an abutting side surface; a measurement surface; and an axis line marker that enables a tilt relative to the X axis to be detected.

Abstract: A method includes: performing a scanning measurement of a female thread along first and second axes extending along a center axis of the thread and opposed to each other across the center axis; determining characteristic values of the thread from contour data of the thread obtained through the measurement; obtaining the contour data including first contour data associated with the first axis and second contour data associated with the second axis by performing the measurement; detecting a thread displacement along the center axis between a crest associated with the first axis and a crest associated with the second axis at each of first position and second position on the center axis; calculating inclination and deviation of the first and second axes from the thread displacements detected at the first and second positions; and adjusting an attitude of the thread for the measurement to eliminate the inclination and deviation.

Abstract: A roundness measuring device includes an annular ring, and a plurality of displacement sensors (comparative length measuring devices) provided on the ring at predetermined intervals. The displacement sensors are arranged such that lines along which measurement axes of the displacement sensors extend intersect at a single point.

Abstract: A roundness measuring machine includes: a base; a table rotatable relative to the base; a probe configured to scan a surface of a workpiece mounted on the table; a motor configured to rotate the table; and a control device configured to control a rotation of the motor. The control device includes: a starting current detector configured to detect a starting current of the motor; and an acceleration/deceleration time setting unit configured to detect at least one of acceleration time and deceleration time for the motor in accordance with the starting current. The roundness measuring machine can suitably set the acceleration time and the deceleration time for the motor corresponding to the inertia moment of the workpiece mounted on the table.

Abstract: A profile measuring instrument usable to perform a rotary scanning measurement and a linear scanning measurement on a workpiece in the form of a revolution solid, includes: a turntable on which the workpiece is mounted, the turntable being rotatable around a predetermined rotation axis; a rotary scanning measurement unit being adapted to measure a displacement of a surface of the workpiece mounted on the turntable; a linear scanning measurement unit being adapted to measure a profile of the surface of the workpiece mounted on the turntable along a predetermined measurement axis; and an aligning mechanism being adapted to relatively move the linear scanning measurement unit and the turntable in a direction intersecting with the measurement axis. The linear scanning measurement unit and the turntable are adjusted to relative positions at which the measurement axis passes through the rotation axis.

Abstract: A lens-measuring machine includes: a table rotatable around a rotation axis; a lens holder that holds a workpiece in a form of a lens, the lens holder being placed on the table so that an optical axis of the lens becomes orthogonal to the rotation axis; a contact tip that contacts a measurement surface of the lens; an angle sensor for detecting a rotary angle of the table; a displacement detector for detecting a displacement of the contact tip; and a controller for calculating coordinates information of the measurement surface of the lens in a form of polar coordinates, whose origin is at the rotation axis, based on displacement of the contact tip for every predetermined rotary angle of the table, the controller converting the calculated polar coordinates into Cartesian coordinates.
