Abstract: A monitoring device monitors a status of a process in a production line in separate unit tasks. The production line includes a plurality of processes. The unit tasks form the process. The monitoring device includes an operational condition acquisition section, a determination section, and an output section. The operational condition acquisition section acquires, on a per-unit task basis, operational conditions of a device being used in the tasks. The determination section determines whether or not the acquired operational conditions are appropriate based on preset reference values. The output section outputs, on a per-unit task basis, information as to whether or not the process is being appropriately performed, based on results of the determination.

Abstract: A machine tool for machining a workpiece includes a spindle configured to rotate a holder mounted with a tool used for machining, one or more moving shafts configured to move the holder and/or a work base on which the workpiece is placed, a torque measurement unit configured to measure driving torque of the spindle and/or the one or more moving shafts, a reference value calculation unit configured to use, as a reference value, the driving torque measured by performing a no-load operation by rotating the spindle in a normal state, a torque comparison unit configured to compare, to the reference value, the driving torque measured by performing a no-load operation by rotating the spindle before actual machining, and an alarm unit configured to determine whether to issue an alarm on the basis of results of the comparison.

Abstract: An incident management device includes: an issued ticket receiving unit that receives a ticket corresponding to the incident, the ticket being issued by the computer of the end user site with respect to the computer of the call center of the customer; a reply receiving unit that receives a reply to the issued ticket, the reply being sent from the computer of the call center of the customer to the computer of the end user site; an additional ticket receiving unit that receives an additional ticket to which new information related to the same incident as the ticket can be added, the additional ticket being issued by the computer of the end user site; and an information providing unit that provides a retrieval result in response to an inquiry request for the incident sent from the computer.
