“…Luo et al [ 22 ] integrated the PVDF thin-film sensors into the index-able tools to measure cutting forces acting on separate insert, the signals are transmitted by a wireless transmitter, and the signals are then used to identify the insert working condition in the milling process. Liu et al [ 23 ] designed an integrated rotating dynamometer based on fiber Bragg grating (FBG) to measure four-component cutting force. These methods mainly integrate sensing components into the cutting tool, however, this is easy to be disturbed by the machining process since rigidity of the spindle is relatively low.…”

In the milling process, cutting forces contain key information about the machining process status in terms of workpiece quality and tool condition. On-line cutting force measurement is key for machining condition monitoring and machined surface quality assurance. This paper presents a novel instrumented working table with integrated polyvinylidene fluoride (PVDF) thin-film sensors, thus enabling the dynamic milling force measurement with compact structures. To achieve this, PVDF thin-film sensors are integrated into the working table to sense forces in different directions and the dedicated cutting force decoupling model is derived. A prototype instrumented working table is developed and validated. The validation demonstrates that profiles of the forces measured from the developed instrumented working table prototype and the dynamometer match well. Furthermore, the milling experiment results convey that the instrumented working table prototype could also identify the tool runout due to tool manufacturing or assembly errors, and the force signal spectrum analysis indicates that the developed working table can capture the tool passing frequency correctly, therefore, is suitable for the milling force measurement.

Industrial Revolutions marked periods of exponential growth in the industrial sector. Among the technologies immersed in this area is fiber optics, which was initially used in the telecommunications industry, but is currently present in several industrial sectors. More specifically, this work addresses its applications in Instrumentation associated with the concept of Bragg grids. In this paper is published a brief introduction to fiber Bragg gratings (FBG), aiming to present an analysis of the most recent articles related to the use of fiber Bragg grating in industrial sensors. We selected 19 papers to show the results and the positive and negative data of this technology. Although it is a promising technology, it still needs standardization with the conventional industry environment.

“…However, the entire measurement structure is relatively large, and the compatibility needs to be improved. Liu, M. et al develop a tool holder based on fiber Bragg grating sensor for cutting force measurement, with a maximum sensitivity of 1.08 με/N and a natural frequency of 320 Hz [ 11 ]. The tool holder was designed as an octagonal ring structure, and the sensor was pasted on the sensitive structure of the tool holder.…”

On-line cutting force measurement is an effective way to monitor processing quality, improve processing accuracy, and protect the tool. In high-speed and ultra-precision machining, status monitoring is particularly necessary to ensure machining accuracy. However, the cutting force is very small in high speed and ultra-precision machining. Therefore, high-sensitivity cutting force sensors are needed. Current commercial cutting force sensors have defects such as large volume, low compatibility, and high price. In particular, the sensitivity of cutting force sensor needs to be improved for high-speed and ultra-precision machining status monitoring. This paper provides a possible solution by embedding the sensor in the tool and selecting sensitive materials with high piezoresistive coefficient. In this paper, the structural design of the sensor and the fabrication of the sensitive material SiAlCO ceramic are carried out, and then the sensor is packaged and tested. The test results show that the cutting force sensor’s sensitivity was as high as 219.38 mV/N, which is a feasible way to improve cutting force sensor’s compatibility and sensitivity.
