“…To obtain complete axial and transverse force decoupling, they established a sophisticated arrangement of four FBG sensing points, leading to reliable consistency and sensor repeatability of 1.3 pm/N. In another publication, Liu et al [172] reported a prototype of a smart spindle based on the FBG strain detection principle to analyze and track cutting forces during the machining process. Additionally, Guo et al [173] managed to eliminate cross-talk effects and presented a three-axis force robotic fingertip relying on a single fiber of three pairs of FBGs.…”

In the era of digitalization, there is a huge focus on capturing data from manufacturing processes and systems. Since the promotion of Industry 4.0, the industrial marketplace has been crowded with solution providers who excel in capturing and aggregating data on the cloud and presenting it on dashboards. From machine states to production targets, this type of data has become more readily available from tools, controllers, switches, and factory bus systems. As the industry pushes deeper into the machine for information and aspires to have smart machines that can feel and react to experiences during the manufacturing process, then more sophisticated technology is necessary. Strain sensor technology is a logical measurement principle to address this challenge for many industrial sectors. For researchers and industrialists to progress toward the smart machine agenda, there must be a firm grasp of the "technology-solution fit," i.e., what strain technology could provide the most appropriate solution. This paper presents a review of the state of the art in strain sensors that are foreseen as frontrunners to enable next-generation smart components and intelligent tools. The review focuses on industrial strain sensing technologies that are at a mature place on the technology readiness levels (TRLs) and present themselves as highly practical solutions for smart components and digitized machines, considering sensitivity, powered or passive, wired or wireless, and robustness. Through this review, researchers and industrialists will have a suite of solutions to move on with their innovative designs of smart machines based on embedded strain sensor technology.

Purpose The use of a force sensor to estimate the external force of manipulator not only needs to deal with the signal noise of the sensor itself but also needs to solve the coupling interference of the sensor itself, especially the axial force. The purpose of this paper is to develop a three-dimensional fiber Bragg grating (FBG) wrist force sensor, which has a simple structure and reduces the coupling influence between several axes. Design/methodology/approach A particular separation elastic structure with four FBGs is devised for the three-axial force sensor. One FBG is suspended on the profile of central cylinder and the other three FBGs are pasted on the elastic beam surface of the over and under measuring bodies, respectively. Finite element analysis (FEA) simulation has been implemented to the strain distribution characteristics, the output characteristics of each direction and the coupling effects of the structure. Furthermore, theoretical derivation and experimental results are used to compare, which have a good consistency. Findings The experiment results show that the maximum repeatability error of the sensor is 6.75%, the maximum nonlinear error is 5.36%, the maximum coupling interference is 4.73% and the minimum sensitivity is 1.58 pm/N. Originality/value A three-dimensional force sensor based on FBG adopts a particular separation elastic structure. The sensor can reduce the coupling influence between several axes, especially the coupling interference in the z-direction is 0.

“…In table dynamometers, elastic structures include the octagonal ring [ 7 , 8 ], the oval octagonal ring [ 9 ], the ring [ 10 ], and so on. For rotating dynamometers mounted on the spindle, elastic structures consist of a cylindrical deformation beam [ 11 ], Γ beam-type [ 12 , 13 ], E-type diaphragm [ 14 , 15 ] and others. In contrast to table dynamometers, rotating dynamometers have several advantages, such as less intermediate force transmission components, allowing for various cutting tools sizes and force configurations.…”

Cutting force measurement is of great importance in machining processes. Hence, various methods of measuring the cutting force have been proposed by many researchers. In this work, a novel integrated rotating dynamometer based on fiber Bragg grating (FBG) was designed, constructed, and tested to measure four-component cutting force. The dynamometer consists of FBGs that are pasted on the newly designed elastic structure which is then mounted on the rotating spindle. The elastic structure is designed as two mutual-perpendicular semi-octagonal rings. The signals of the FBGs are transmitted to FBG interrogator via fiber optic rotary joints and optical fiber, and the wavelength values are displayed on a computer. In order to determine the static and dynamic characteristics, many tests have been done. The results show that it is suitable for measuring cutting force.
