“…However, this method changes the original components of the machine tool, and the supporting measurement system is expensive and has poor promotion performance. Chen et al [96] developed an intelligent toolholder composed of a piezoelectric ceramic force sensor and a flexible hinge, which can be integrated with a fast tool servo for three-way cutting force measurement in micro/nano cutting. The cutting test results show that the intelligent toolholder has a force measurement resolution of 0.1 mN, 0.05 mN, and 0.1 mN in the X, Y, and Z directions, and can sensitively detect tiny chatter with an amplitude of 20 nm.…”

In the manufacturing process, in addition to the properties of material itself, the quality of a product is directly related to the cutting process. Cutting force and cutting heat are two crucial factors in cutting processing. Researchers can analyze various signals during cutting process, such as cutting force signal, vibration signal, temperature signal, etc., which can regulate force and temperature, optimize the cutting process, and improve product quality. Therefore, it is very important to pay attention to various signals in cutting process. Meanwhile, good-quality signal data sets will greatly reduce time, resource and labor costs for subsequent use or analysis of researchers. Therefore, how to collect high-quality signals effectively and accurately is the first step. At present, researchers prefer to use various sensors to collect signals. With the advancement of science and technology, intelligent tool holder appears in researchers' vision. It integrates multiple systems such as sensors, data collection, data transmission, and power supply on the tool holder. It replaces traditional wired sensors, and it is highly interactive with CNC machine tools. This paper will carry out a systematic review and prospect from three aspects: the structural design of the intelligent tool holder, the signal monitoring technology of the intelligent tool holder, and the tool condition monitoring of the intelligent tool holder.

“…In practical applications of ultra-precision machining, semiconductor industry and biomechanics field, there are many cases where it is necessary to measure static or quasistatic micro forces by force sensors, such as constant cutting force machining and measuring machining forces in real time for monitoring the machining status [14,15], micro constant force servo for surface measurement [5], sensing and positioning based on force signal [7,9], etc. The force gauge based on the principle of strain gauge can measure static force [16], but its sensitivity and stiffness are much lower than the piezoelectric sensor so that the application of the piezoelectric sensor could not be replaced by the commercial force gauge.…”

Ordinary piezoelectric force sensors are only capable of measuring dynamic forces but not static forces because of the charge leakage due to the finite resistance of piezoelectric materials and charge amplifiers. This paper presents a new strategy for in-process compensation of charge leakage for force measurement with wide spectrum from static to dynamic realized by piezoelectric force sensors. The compensation is in-process operated based on the concept of dynamic accumulation. In order to improve the measurement accuracy and long-term stability by the compensation, the zero offset generated by normalization, bias current and temperature drift are all theoretically analyzed and experimentally validated. Measurement experiments of four different types of force signals, which contain static, triangle, sinusoidal and random force signals acting on the piezoelectric force sensor, are conducted to validate the proposed strategy. In addition, the effect of different time constant of the piezoelectric sensor under different applied forces on the compensated results is analyzed. Performance tests contain accuracy, resolution, span and bandwidth have been conducted. It is validated that the proposed method has high sensitivity of sub-millinewton, long-term stability and wide spectrum from static signal to dynamic measurement capabilities, which would provide an effective and precise method for micro force measurement and control in ultra-precision machining, semiconductor industry and biomechanics fields.
