Zusammenfassung:To provide a control device and a program capable of detecting machining abnormalities from more elements.SOLUTION: A control device that controls a machine tool which can be stopped in an alarm situation based on an abnormality in a machining load is comprised of: an imaging unit that captures a chip produced as a result of machining a work-piece; in response to an occurrence of an alarm stop, a reference model determination unit that determines a reference model of chips for determining a processing abnormality in advance based on images of the chips taken within a predetermined period before the alarm stop occurs; and a determination unit for determining that an abnormality has occurred in the processing when a similarity of the chips imaged at a predetermined timing in the subsequent processing is equal to or higher than the predetermined value with respect to the determined reference model of the chips.SELECTED DRAWING: Figure 1 【課題】より多くの要素から加工の異常を検出することが可能な制御装置及びプログラムを提供すること。【解決手段】加工負荷の異常に基づいてアラーム停止可能な工作機械を制御する制御装置であって、ワークの加工の結果生成される切粉を撮像する撮像部と、アラーム停止の発生に応じて、アラーム停止以前の所定期間内に撮像された切粉の画像に基づいて、加工の異常と判定するための切粉の基準モデルを予め決定する基準モデル決定部と、決定された切粉の基準モデルに対して、後の加工において所定タイミングで撮像される切粉の類似度が所定以上である場合に、加工の異常発生と判断する判断部と、を備える。【選択図】図1
