A measuring apparatus management system of the present invention includes an acquirer acquiring condition information indicating a status of a replacement component in each of a plurality of measuring apparatuses, and a predictor predicting a replacement time of the replacement component based on the condition information obtained by the acquirer.

Measuring apparatus management system and program

Provided is method of calibrating Y-axis direction position of contact tip of form measuring instrument including: table rotatable about Z-axis; contact tip capable of contacting workpiece; and contact tip driving means to drive contact tip in at least X- and Z-axis directions among X-, Y- and Z-axis directions perpendicular to one another. Method performs tracing measurement of inclined surface or inclined cylinder side surface which is part of workpiece obtained by inclining workpiece placed on table about Y-axis, or side surface of off-centered cylinder having center axis off-centered in X-axis direction by rotating surface to obtain measurement value at each angular position of rotation of table, obtains angular position of rotation at which smallest value among measurement values of tracing measurement is detected as angular position of rotation with smallest detected value, and adjusts Y-axis direction position of contact tip based on angular position of rotation with smallest detected value.

Form measuring instrument, and calibration method and calibration program therefor

Form measuring instrument includes: first measuring means which moves contact piece from first position in parallel with second axis to trace surface of workpiece, measure amount of displacement of contact piece, to obtain first profile; second placing means which rotates workpiece about first axis by 90 degrees to place workpiece at second position from first position; second measuring means which moves contact piece from second position in parallel with second axis to trace surface of workpiece, measure amount of displacement of contact piece, to obtain second profile; extremum position calculating means which fits circles to first and second profiles and calculate positions, in direction parallel with second axis, of first and second extremums indicating circles' extremums; and moving means which moves workpiece in direction parallel with second axis and direction parallel with third axis such that positions, in direction parallel with second axis, of first and second extremums become 0.

Form measuring instrument, form measuring method, and program

A form measuring instrument comprising: a roughness sensor placed on the table, and for outputting measurement data that includes information on the cross-sectional shape; a relative movement mechanism for relatively moving the table and the roughness sensor such that the position of the roughness sensor on the workpiece is relatively moved along the surface to be evaluated, and for outputting the amount of relative movement at a movement resolution &#x394;&#x3b8; as indexed-movement-amount information; a time sampler for sampling the measurement data output from the roughness sensor, at a constant time interval t; and a data processing mechanism for converting the measurement data sampled at the constant time interval tby the time sampler to measurement data having a fixed interval according to the indexed-movement-amount information output from the relative movement mechanism.

Form measuring instrument

A surface texture measuring instrument has a rotary table on which a workpiece is rotatably mounted, a Z-axis slider capable of moving in a Z-axis direction parallel to a rotation axis of the rotary table, an X-axis slider that is held by the Z-axis slider and is advanceable and retractable in an X-axis direction orthogonal to the rotation axis, a first arm that is held by the X-axis slider and is rotatable around a center line parallel to the X-axis, a second arm that is held by the first arm and is advanceable and retractable in a direction orthogonal to the X-axis, and a detector held by the second arm to measure a surface texture of the workpiece.

Width-measuring method and surface texture measuring instrument

The object of the invention is to provide a method, a program and a device that can set accurately and easily the origin of the coordinate system of a workpiece based on the result obtained by a surface texture measuring machine scanning over a feature area on the surface of the workpiece. The device comprises a data inputter for inputting data obtained by scanning a feature area including at least a feature point area and a non-feature point area of the surface of a workpiece, a feature point selector for extracting the feature points of the data by statistically processing the data inputted into the data inputter and an origin setter for setting the origin of a workpiece coordinate system relative to an origin setting target point of the workpiece based on the coordinate values of the feature point obtained by the feature point selector.
