“…The integration of sensors on fixtures has also been investigated. Liu et al [10] integrated PVDF thin-film sensors into fixtures to monitor the cutting forces on thin-wall aircraft structural parts. Rezvani et al [11] have replaced the jaws of a vice with sensor integrated plates with strain gauge and PZT sensors to monitor the clamping force and cutting forces during milling.…”
The future of manufacturing processes is the fully autonomous operation of machine tools. The reliable autonomous operation of machine tools calls for the integration of inline quality control systems that will be able to assess in real time the process status and ensure that the machine tool, process and workpiece are complying with the manufacturing tolerances and requirements. Sensor integrated tooling for machining processes can significantly contribute towards this goal as they can facilitate monitoring close to the actual process. However, most of the solutions proposed so far are highly expensive or very complex to integrate and operate in an industrial environment. To this end, this paper proposes an approach for a sensor integrated vise using low-cost industrial sensors that can easily be integrated in existing machine tools in a non-invasive fashion. The development and dynamic analysis of the system is presented, along with an experimental verification against a lab-scale, high accuracy sensing setup
“…Recently, different types of applications using thin-film sensors are being explored by the scientific community in industrial applications. Examples are the monitoring of cutting forces in a milling process [7], the wireless acquisition of the temperature in tools [6], and the monitoring of tool wear [9]. However, the use of thin-film sensors surfaces requires reliable systems for the conditioning of the acquired signal.…”
Section: Data Acquisition and Signal Conditioning In Thin-film Sensorsmentioning
Thin-film sensors surfaces are becoming popular to collect data in several specific and complex processes, namely plastic injection or metal stamping, allowing the digitization of such processes through the use of Internet of Things technologies. A particular challenge in such thin-film sensors surfaces is the data acquisition and signal conditioning system, which implementation is complex due to the characteristics of these sensors (e.g., low amplitude and noisy signals), but even more complex when implemented in real industrial processes, which are subject to harsh conditions, namely noise, dirt and aggressive elements. This work describes a modular data acquisition and signals conditioning system for thin-film sensors surfaces, meeting the requirements of scalability, robustness and low-cost, meaning that it can be easily expanded according to the number of sensors required for the application scenario.
