  • Patent number: 11376701
    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.

  • Publication number: 20200183372
    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.
