Summary:To provide a monitoring device that can easily monitor a processing device using a threshold value suitable for each of processing stages.SOLUTION: The present monitoring device monitors a machining device that performs machining including a plurality of machining stages with different machining conditions according to a machining program. The present monitoring device comprises: an acquisition unit that reads a machining program and acquires a plurality of machining stages which the machining program causes the machining device to execute; a collection unit that collects monitoring target data for each of the plurality of machining stages of the machining device which operates according to the machining program; a determination unit that determines a threshold value of a machining stage from which a predetermined number of monitoring target data have been collected by the collection unit among the plurality of machining stages, using the collected predetermined number of monitoring target data; a monitoring unit that starts monitoring the processing device in the machining stage for which the threshold value has been determined, using the determined threshold value; and an output unit that notifies a detected abnormality when the abnormality in the processing device is detected by the monitoring unit.SELECTED DRAWING: Figure 4 【課題】加工段階の夫々に適した閾値を用いた加工装置の監視を容易に実行できる監視装置を提供する。【解決手段】本監視装置は、加工プログラムにしたがって、加工条件の異なる複数の加工段階を含む加工を行う加工装置を監視する。本監視装置は、加工プログラムを読み込んで、加工プログラムが加工装置に実行させる複数の加工段階を取得する取得部と、加工プログラムにしたがって動作する加工装置の複数の加工段階の夫々について、監視対象データを収集する収集部と、複数の加工段階のうち、収集部によって所定数の監視対象データが収集された加工段階の閾値を、収集した所定数の監視対象データを用いて決定する決定部と、閾値が決定された加工段階における加工装置に対して、決定された閾値を用いた監視を開始する監視部と、監視部によって加工装置の異常が検出されると、検出された異常を通知する出力部と、を備える。【選択図】図4
