This paper proposes a novel evaluation method for worked metal surface using haptic information.With the decrease in production due to the decreasing birthrate and aging population as a background,the development of technology to replace the human delicate motion is strongly required.Haptic information,which is the one of important factor of human senses,is focused on in this paper.The main subject of this paper is to propose a method for quantitative treating the haptic information.In particular,the vibration component of in rubbing motion is evaluated.To evaluate the haptic information in frequency domain,Cepstral analysis is utilized.Cepstral analysis,which is used in audio analysis,is useful method to check the characteristics in detail in the frequency domain.The validity of the proposed method was confirmed by experiments by 2-DOF system.With the proposed method,the technology relying on the human sense can be quantified.
