Abstract: A control method of a shape measuring apparatus divides a curve indicating a movement path of a probe into a plurality of sections. A measurement target section is selected from the plurality of sections sequentially from a starting point side of the curve indicating the movement path of the probe. A first curvature radius is calculated from a curvature of the measurement target section. A second curvature radius is calculated according to an angle between a first straight line connecting a starting point to an ending point of the measurement target section and a second straight line connecting a starting point to an ending point of a section next to the measurement target section. A smaller value from among the first curvature radius and the second curvature radius is set as an effective radius. A maximum speed of probe movement increasing according to an increase in the effective radius is calculated for the measurement target section.

Abstract: During a retraction where a stylus tip separates from a work piece from a state where the stylus tip and the work piece are in contact, whether there is contact between the stylus tip and the work piece is monitored. When the contact between the stylus tip and the work piece is detected during the retraction, a probe is displaced to a position where the stylus tip does not come in contact with the work piece and a recovery process is executed. When a distance between a point on a surface of the work piece at a retraction start point and a contact point between the stylus tip and the work piece is Lm, and a value defined by (Lm−d) multiplied by a coefficient k (0

Abstract: Stylus head displacer displaces a stylus head on a first measurement path. A path definer defines the first measurement path. A displacement controller controls the stylus head displacer such that the stylus head displaces along the first measurement path. A position detector detects a position of the stylus head. A depression amount detector detects the depression amount of the stylus head. A measurement results memory stores the position and amount of depression of the stylus head. The depression amount detector outputs an error signal when detecting a measurement error. The displacement controller stops displacement of the stylus head in response to the error signal and displaces the stylus head to a starting point of the first measurement path, and controls the stylus head displacer such that the stylus head is displaced from the starting point to an end point of the first measurement path with a fixed depression amount.

Abstract: A scanning path is divided after every predetermined number of segments and a set of measurement commands is defined for each of the predetermined number of segments. While executing the measurement command, a speed pattern plan is created for the following measurement command. At this time, planning is conducted such that a final speed of a speed pattern plan of the measurement command is the same as an initial speed of the speed pattern plan of the following measurement command. While executing the measurement command, a gap time (from a current time to an estimated end time of the measurement command) is calculated continuously. When the gap time is longer than a planning calculation time, the initial speed of the speed pattern plan of the following measurement command is kept the same as the final speed of the speed pattern plan of the measurement command.

Vc2 is represented by (Vc1·q)q, Vc1 is a vector in a direction correcting a probe position such that a stylus tip is oriented along a scanning course, q is a vector given by a vector product of the normal line of a surface of the work piece and Vf, The normal direction of a measured surface is designated as Nw, p is a scalar product of Vc2 and Nw, and sg(p) is a function returning +1 or −1 in accordance with a value of p.
