The present invention has an object of providing a management system capable of predicting a malfunction occurrence rate that takes account of installation conditions and operating conditions of individual machining apparatuses. A management system that manages machining apparatuses which uses coolant, includes: an acquisition unit that acquires duration information including an installed duration and operating duration of the machining apparatus and condition information based on the installed duration and operating duration of the machining apparatus for each of the machining apparatuses; an analysis unit that analyzes a malfunction occurrence rate for each of the machining apparatuses, based on the duration information and the condition information, as well as the malfunction occurrence information of the machining apparatus caused by coolant; and a notification information generation unit that outputs notification information based on the analyzed malfunction occurrence rate.

A rotation angle detecting device includes: a rotating part rotating integrally with the rotating shaft and including a detected portion; an A-phase detector detecting change of a physical quantity caused by rotation of the rotating part, inside a first detection field over the detected portion and outputting an A-phase signal; and a B-phase detector detecting change of the physical quantity caused by rotation of the rotating part, inside a second detection field located over the detected portion and outputting a B-phase signal that is out of phase with the A-phase signal. The second detection field is shorter than the first detection field with respect to the direction perpendicular to the rotating direction of the rotating part.

Rotation angle detecting device

A rotation angle detector comprises a rotating body including a plurality of track parts, and an abnormality detecting unit for detecting an abnormality based on signals generated in detection units. The detection units generate a first signal based on a first track part and a second signal based on a second track part. The abnormality detecting unit includes a judgement unit for judging an occurrence of an abnormality when the difference between the fluctuation range of the first signal and the fluctuation range of the second signal is larger than a predetermined fluctuation range judgement value.

A manufacturing adjustment system includes a decision part and a tolerance setting part. The decision part decides whether part dimensions calculated by a part dimension calculation part fall within a predetermined range of dimensions and a total machining time calculated by a total machining-time calculation part falls within a predetermined time. The tolerance setting part sets a workpiece tolerance for each machine based on the decision result of the decision part when the workpieces are produced by the machines.
