| description | To provide a processing state estimation method and a processing state estimation system that can accurately estimate a processing state of a workpiece.SOLUTION: A processing state estimation system 1 includes an observation device 20 and an estimation arithmetic device 30. The estimation arithmetic device 30 includes: a signal acquisition unit 31 for acquiring an AE signal S from the observation device 20; a total effective value arithmetic unit 32 for calculating a total effective value J1 of the AE signal S; a frequency region effective value arithmetic unit 33 for calculating an effective value J2 of a partial frequency region of the AE signal S; and a ratio arithmetic unit 34 for calculating a ratio K being interrelated with a processing state, using scaling by dividing the effective value J2 by the effective value J1. The processing state estimation system estimates a processing state that is interrelated with the ratio calculated by the ratio arithmetic unit 34.SELECTED DRAWING: Figure 4
【課題】工作物の加工状態を精度良く推定することができる加工状態推定方法及び加工状態推定システムを提供すること。【解決手段】加工状態推定システム１は、観測装置２０及び推定演算装置３０を備える。推定演算装置３０は、観測装置２０からＡＥ信号Ｓを取得する信号取得部３１と、ＡＥ信号Ｓの全体の実効値Ｊ１を算出する全体実効値演算部３２と、ＡＥ信号Ｓの一部の周波数領域の実効値Ｊ２を算出する周波数領域実効値演算部３３と、実効値Ｊ２を実効値Ｊ１で除することにより基準化して、加工状態と相関関係にある比率Ｋを算出する比率演算部３４と、を有して、比率演算部３４によって算出された比率と相関関係にある加工状態を推定する。【選択図】図４ |
