The first acquisition unit is configured to acquire, from a machine tool, context information including at least a monitoring specifying number identifying a machining process. The second acquisition unit is configured to acquire detection information output from a detection unit installed for the machine tool. The associating unit is configured to associate the monitoring specifying number included in the context information acquired by the first acquisition unit and the detection information acquired by the second acquisition unit.

Abstract: Provided is an abnormality detection device with which an abnormality of a machining state of a machine tool can be detected based on information on a section where machining is actually performed in machine tool-based machining. The abnormality detection device detects an abnormality of a machining state of a machine tool machining a workpiece with a tool. The machine tool includes a determination unit determining the machining state by using information related to an actual cutting section in the tool-based machining of the workpiece in the machine tool. The determination unit performs the machining state determination by using a deviation in position and length of a section recognized as the actual cutting section and a physical quantity in the actual cutting section acquired from the machine tool.

Abstract: A warm-up control system for a machine tool drives a spindle motor for rotating a main spindle of the machine tool before starting machining, thereby performing a warm-up operation, and acquires a spindle motor load value that is variable by heat generated during the warm-up operation. The warm-up operation is ended when the acquired spindle motor load value becomes substantially equal to a preset working reference load value. The cutting capacity of the main spindle can be improved by this warm-up operation.
