Force Control of Grinding Process Based on Frequency Analysis

Hysteresis-induced drift is a major issue in the detection of force induced during grinding and cutting operations. In this letter, we propose an external estimation method based on Mel spectrogram obtained from sensor. We focus frequent strong correlation between vibration frequency operations with periodic vibrations. The information found to be more effective for accurate than amplitude cases large noise caused by vibration. experimentally demonstrate that combines neural network robust against drift.
