Abstract: This machining system comprises: a CAM device for generating, on the basis of three-dimensional shape data, a machining program including an operation code; and a numerical control device for controlling an electric motor of a machine tool. The machining system is provided with a monitoring device for detecting an abnormality of the machine tool on the basis of a drive state of the electric motor. The machining system is provided with a revision device for generating a revision command for revising a parameter for when the CAM device generates the machining program. The revision device transmits the revision command to the CAM device so as to revise the curvature of a tool path and/or the feed rate of a tool for when the abnormality occurred.

Abstract: The processing time monitoring device is intended to monitor processing time of the target device, and includes: a data acquisition unit that acquires time series data of the target device as input time series data; a time difference calculation unit that calculates a time difference between the input time series data and reference time series data, the time difference existing in a direction of a time axis; and a display unit that displays the time difference calculated by time difference calculation unit.

Abstract: A tool replacement timing management system includes a data acquisition section configured to acquire time series data indicating a machining state from a machine, a data cutout section configured to cut out specimen data from the time series data according to at least one condition or a combination of conditions selected from among machining, a tool, a workpiece, and a tool speed, a machining state variable calculating section configured to calculate a machining state variable, which is a statistical index, from the specimen data, a tool deterioration state generation section configured to generate tool deterioration state data in which the machining state variable is aligned in a time series, and a tool replacement timing calculating section configured to calculate a tool replacement timing on a basis of the tool deterioration state data.
