“…One example is through use of novel wireless passive sensor systems reported by Stoney et al [15] based on use of surface acoustic wave strain sensors. Similarly it is becoming more realistic to consider great multisensory data sets using measurable phenomena such as spindle power correlated with tool engagement.…”

“…Figure 5.1 shows the power data mapped onto the surface of medical implant during grinding [16]. Example of (a) wireless sensing of strain during turning [15] and (b) power mapping to freeform surfaces [16] The concept that every executed line of G-code is an experiment as postulated by Park et al [17] shows how process data is becoming more visible and useable. Quantification of other factors that impact directly on cutting processes is also becoming more feasible with new sensor technology such as monitoring of coolant quality inline [18].…”

We are rapidly moving into the new era of digitisation, into an era of the Massive Internet of Things -towards the Gigabit Society and towards 5G Technology. The implications are truly far reaching. Rapid transformation through the implementation of INDUSTRY 4.0 is becoming visible in industries all over the world. Disruption to the more traditional industrial practices and processes is inevitable. High Performance Cutting is no exception. Developments in the Internet of Things (IoT) opens up new and extremely powerful capabilities to help us gain a significantly deeper understanding of the fundamentals of cutting processes and offers entirely new connectivity possibilities at all interfaces, some old and some new, "between the Chip Root and the Cloud". This supports us in our attempts since the foundation of CIRP in 1951 to remove technological roadblocks and can lead on a new journey towards new and unprecedented scientific/technological developments as well as new business models for companies involved in the various elements of the supply chain for cutting processes (DIN 8580). "Performance" will take on a new and unanticipated meaning over what was originally meant when we established this CIRP-HPC Conference back in the early 2000's. In this paper a critical review of a previous roadmap is undertaken for cutting processes presented in a CIRP Keynote Paper in 2003 by Byrne, Dornfeld and Denkena [1] and new thoughts and ideas are presented on a vision for a 2020 skeleton Roadmap for High Performance Cutting in the new age of Digitisation.

“…Commercial solutions allow real-time and continuous monitoring of temperature in critical electric power transmission and distribution assets [ 5 ]. SAW sensors have also been used to measure the cutting forces in computer numerically controlled (CNC) turning [ 6 , 7 ] and strain on rotating shafts [ 8 ]. The strain sensitivity of SAW sensors was studied on Chip-level by Hempel and his co-workers [ 9 ].…”

Real-time monitoring of torque in a rotating shaft is not easy to implement with technologies such as optic fiber sensors or strain gages. Surface acoustic wave (SAW) sensors are wireless and passive and can be used to monitor strain in moving parts. Commercial solutions (sensors, antennas and interrogation unit) can easily be purchased from some companies; however, they are not customized and may not meet the specificity of the measurements. In order to evaluate the adequacy of commercial off-the-shelf (COTS) solutions, temperature and strain sensors fabricated by SENSeOR (Besançon, France) were mounted on a load cell. The sensors were calibrated using a thermal chamber and a universal testing machine. The load cell was then assembled together with a steel shaft that rotated at different speeds inside an oven. The commercial antennas were replaced with an RF (radio frequency) coupler and the sensors were interrogated with the commercial interrogation unit. The influence of rotation in the accuracy on the measurements, as well as the adequacy of the sensors structure, was evaluated. It can be concluded that SAW sensors can be used to measure temperature or torque in a rotating environment; however, some customization of the components is required in order to overcome the limitations posed by COTS sensing solutions.

Usually, multipath propagation, delay spread, multipath fading, and Doppler effect are important factors causing transmission errors of wireless sensors in manufacturing environment.…”

Surface acoustic wave sensors offer overwhelming advantages over other potentially competitive sensing technologies in rotating mechanical structures for their wireless and passive capability. Nevertheless, the challenges of using these sensors have not been adequately addressed. Radio frequency signal of surface acoustic wave sensors acts as not only the role of data transmission but also the role of energy supply during the sensing system working process. Thus, the performance of surface acoustic wave sensors when they are used to monitor rotating spindles should be investigated due to the harsh metallic environments for radio propagation in machine tool. This article aims to experimentally study the performance of surface acoustic wave sensors on both rotating spindle with Computer Numerical Control machine tool and self-developed spindle apparatus. The measurement study is performed using a temperature surface acoustic wave sensor working in the Industrial Scientific and Medical (ISM) band (433.05-434.79 MHz). Experimental results have shown that transmission and measurement characteristics were closely depended on the surface acoustic wave sensor installation location and rotation speeds. The conclusions will directly guide the sensor location optimization, power setting, errors avoidance, or correction in the future work.
