“…dynamic inertial disturbances deriving from the undesired but unavoidable oscillations of the modal mass placed in front of the piezoelectric load cells in case of plateform dynamometers; by so doing, even low-frequency vibration modes of the machine tool table where the dynamometer is clamped may cause undesired force fluctuations that cannot be avoided, as explained in [ 12 ].…”

“…The moderate frequency bandwidth of modern dynamometers could be extended in three ways: by improving the device hardware, i.e., by selecting sensors and electromechanical components having higher performances; by improving the mechanical design of the device, e.g., by reducing the modal mass in front of the force sensors as described in [ 12 , 13 , 14 , 15 ]; and by applying advanced filtering techniques to the measured signals, which may considerably extend the frequency bandwidth above the structural limits [ 16 ]. …”

Advanced piezoelectric dynamometers with a wide frequency bandwidth are required for cutting force measurement in high-speed milling and micromilling applications. In many applications, the signal bandwidth is limited by the dynamic response of the mechanical system, thus compensation techniques are necessary. The most effective compensation techniques for a full 3D force correction require an accurate and complex identification phase. Extended Kalman filtering is a better alternative for input force estimation in the presence of unknown dynamic disturbances. The maximum bandwidth that can be currently achievable by Kalman filtering is approximately 2 kHz, due to crosstalk disturbances and complex dynamometer’s dynamics. In this work, a novel upgraded Kalman filter based on a more general model of dynamometer dynamics is conceived, by also taking into account the influence of the force application point. By so doing, it was possible to extend the frequency bandwidth of the device up to more than 5 kHz along the main directions and up to more than 3 kHz along the transverse directions, outperforming state-of-the-art methods based on Kalman filtering.

In this paper, Finite Element Analysis (FEA) used DEFORM TM 3D to construct 6061 aluminum sawing simulation. Before sawing, we pushed the speed and cutting speed under pressure as a sawing process parameters. Then there are three groups of combination conditions in the study. Analysis and discussion based on loading, effective stress, cutting temperature and blade wear. According to the impact parameters the structural design of the saw blade is improved by taking full account of the mutual influence of sawing parameters.

Multi-component cutting force sensing systems in manufacturing processes applied to cutting tools are gradually becoming the most significant monitoring indicator. Their signals have been extensively applied to evaluate the machinability of workpiece materials, predict cutter breakage, estimate cutting tool wear, control machine tool chatter, determine stable machining parameters, and improve surface finish. Robust and effective sensing systems with capability of monitoring the cutting force in machine operations in real time are crucial for realizing the full potential of cutting capabilities of computer numerically controlled (CNC) tools. The main objective of this paper is to present a brief review of the existing achievements in the field of multi-component cutting force sensing systems in modern manufacturing.
