Abstract: A method for nominal scanning measurement includes allowing a user to select a shape of an object to be measured from a geometric shape menu prepared in advance, allowing the user to input, according to the selected geometric shape, a parameter to specify the geometric shape, allowing the user to select a measurement path from a measurement path menu prepared in advance, allowing the user to input, according to the selected measurement path, a parameter to specify the measurement path, calculating, based on the selected geometric shape, the input parameter of the geometric shape, the selected measurement path, and the input parameter of the measurement path, measurement points on a workpiece and a normal line direction at each of measurement points using a calculation formula prepared in advance, and calculating a path for scanning measurement to move while scanning a sequence of the measurement points.

Abstract: A controller of a profile measuring instrument includes: an information acquirer that acquires profile information on a profile of a workpiece and a probe command unit that calculates a probe command value for moving the probe by a movement mechanism based on the profile information acquired by the information acquirer. The probe command value is a value for causing a movement of the stylus tip along a lateral face of an imaginary cone that is imaginarily defined in accordance with the profile of the workpiece based on the profile information, the movement of the stylus tip being performed while a distance between a center of the stylus tip and a reference axis passing through a center of a bottom face of the imaginary cone and parallel to the lateral face of the imaginary cone is kept constant.
