“…Luo and Qin (2018), for example, consider "hybrid machining" as one of the main future developments in production, and they demand a measurement technology suitable for use directly at the processing location, stating the following: "However, currently there is no method to realize on-line measurement of surface integrity." (Jiang et al, 2018). Here, we present a sensor that addresses this problem.…”

Abstract. Manufacturing of high-precision components requires accuracies that even the most modern processing machines are often unable to deliver reliably. Slightly worn tools, incorrectly calibrated sensors or even different trajectories can lead to results that do not comply with the desired specifications. However, quality control is still mainly performed on randomized samples outside the machine tool in special measuring rooms. Therefore, closed-loop quality control becomes a cumbersome iterative process. With HoloPort, we present a digital holographic sensor system that is capable of measuring the complete topography of machined components with sub-micrometer precision directly inside a tooling machine. To our knowledge, HoloPort is the first wireless interferometric sensor inside a machine tool worldwide. As it is fully integrated, it features not only a multiwavelength interferometer but also a miniaturized graphics processing unit (GPU). This allows for full data evaluation directly in the sensor. A single measurement is taken and processed within 3 s during wireless operation. HoloPort is easy to integrate into a variety of machine tools. This contribution includes detailed information about the sensor architecture. Experimental results on milled parts demonstrate the performance of the system and illustrate possible inline applications as well as future perspectives for the sensor.

“…It is becoming more feasible to implement surface metrology on the machine tool and in the manufacturing process with improvements in the stability of the machine tool [80]. In recent years, on-machine and in-process surface metrology is playing an increasingly important role in the process chain of traditional manufacturing that is composed of cutting, grinding and polishing for precision workpieces with complex shapes and/or extremely tight tolerances, such as freeform optics in head-up displays, large roll moulds for roll-to-roll replication and turbine blades of airplanes [220] [108] [27]. Similar trends are observed in the non-traditional manufacturing processes, such as additive manufacturing [199] and nano-scale manufacturing [55] [54].…”

On-machine and in-process surface metrology are important for quality control in manufacturing of precision surfaces. The classifications, requirements and tasks of on-machine and in-process surface metrology are addressed. The state-of-the-art on-machine and in-process measurement systems and sensor technologies are presented. Error separation algorithms for removing machine tool errors, which is specially required in on-machine and in-process surface metrology, are overviewed, followed by a discussion on calibration and traceability. Advanced techniques on sampling strategies, measurement systems-machine tools interface, data flow and analysis as well as feedbacks for compensation manufacturing are then demonstrated. Future challenges and developing trends are also discussed.
