Abstract: There is provided a method for controlling a surface texture measuring apparatus equipped with a probe that cannot detect an edge portion so as to automatically perform edge detection and automatically set a workpiece coordinate system. Accordingly, it is possible to reduce discrepancies by individual operators when setting a coordinate system, and improve the workability of coordinate system setting.A surface to be measured Sw is scanned with a probe 260 along a preset preliminary measurement path PL. When a detection error which causes when the surface to be measured Sw is out of the tracking range of the probe 260 occurs, a measurement value immediately before the detection error has occurred is temporarily registered as a temporary edge point. When the detection error continues during the subsequent scanning is performed for a predetermined distance along the preliminary measurement path, the temporarily registered temporary edge point is set to an edge point.

Abstract: A method of placing a work piece on a measuring device in which a work piece is placed on a table of a measuring device is provided. The method includes: using a retainer capable of holding the work piece above the table and a lifting/lowering device lifting and lowering a top surface of the table; holding the work piece above the table with the retainer; lifting the top surface of the table with the lifting/lowering device to bring the top surface of the table into contact with a bottom surface of the work piece; and, after a load of the work piece is borne by the table, releasing the hold of the retainer on the work piece.

Abstract: A positioning unit includes two or more the laser light sources disposed around a point sensor. Laser light beams from the two or more the laser light sources intersect at an adjustment point separated from a detection point, which is away from the point sensor, by a predetermined distance. The adjustment point is positioned on a desired measurement start point on a work, the point sensor is moved close to the work by the predetermined distance, and a measurement scan of the work is started.
