Zusammenfassung:	To provide a processing state estimation method and a processing state estimation system that can accurately estimate a processing state.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 frequency band effective value arithmetic unit 34 for calculating a respective effective value J of a plurality of frequency bands for the AE signal S; and a surface roughness estimation unit 36 for estimating surface roughness as a processing state, on the basis of an interrelation between the effective value J and the processing state.SELECTED DRAWING: Figure 4 【課題】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について複数の周波数帯域の各々の実効値Ｊを算出する周波数帯域実効値演算部３４と、実効値Ｊと加工状態との間の相関関係に基づいて、加工状態として表面粗さを推定する表面粗さ推定部３６と、を有する。【選択図】図４
