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.

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.
