Abstract: There is provided an automatic measuring system that can automate measurement and a control method for automatic measurement. An automatic measuring system includes a measuring sensor tool that detects a surface of an object to be measured with a probe to measure a dimension or a shape of the object to be measured, and a multi-axis moving mechanism that relatively moves the measuring sensor tool with respect to the object to be measured. The measuring sensor tool includes a cover part to protect the probe. In an approaching step in which the moving mechanism causes the measuring sensor tool to approach a point to be measured of the object to be measured, the cover part accommodates the probe inside the cover part. After the approaching step is completed, the probe is exposed from the cover part to detect the surface of the object to be measured.

Abstract: A coordinate measuring unit includes a measuring probe and a processing device configured to compute the shape coordinates of an object to be measured on the basis of an output of the measuring probe. The measuring probe has a first identification code. The processing device includes a first determination portion configured to determine whether the first identification code outputted from the measuring probe is matched with a matching code, and a downstream determination portion configured to identify a second identification code outputted from the measuring probe to thereby recognize the measuring probe when the first identification code is matched with the matching code in the first determination portion and the measuring probe further has the second identification code. The coordinate measuring unit with the aforementioned configuration can efficiently recognize a number of measuring probes.

Abstract: A measuring probe includes a stylus, an axial motion mechanism, and a rotary motion mechanism. The axial motion mechanism includes a pair of first diaphragm structures that allows a moving member to be displaced, and the rotary motion mechanism includes a second diaphragm structure that allows a rotating member to be displaced. The second diaphragm structure is disposed between the pair of first diaphragm structures in an axial direction. The respective first diaphragm structures are disposed at a symmetric distance with respect to the second diaphragm structure. This can reduce the length in the axial direction and weight thereof and also reduce shape errors and improve measurement accuracy.
