“…Thus, a general and fair conclusion is hard to draw. Hering et al present in [77] a summary of professional distance and ranging sensors giving typical values for commercially available sensors, which cover about 80% of the market according to the authors. This table is reproduced in Table 1 as a base for comparing these common metrology approaches to radar sensors and six-port interferometry.…”

Microwave technology plays a more important role in modern industrial sensing applications. Pushed by the significant progress in monolithic microwave integrated circuit technology over the past decades, complex sensing systems operating in the microwave and even millimeter-wave range are available for reasonable costs combined with exquisite performance. In the context of industrial sensing, this stimulates new approaches for metrology based on microwave technology. An old measurement principle nearly forgotten over the years has recently gained more and more attention in both academia and industry: the six-port interferometer. This paper reviews the basic concept, investigates promising applications in remote, as well as contact-based sensing and compares the system with state-of-the-art metrology. The significant advantages will be discussed just as the limitations of the six-port architecture. Particular attention will be paid to impairment effects and non-ideal behavior, as well as compensation and linearization concepts. It will be shown that in application fields, like remote distance sensing, precise alignment measurements, as well as interferometrically-evaluated mechanical strain analysis, the six-port architecture delivers extraordinary measurement results combined with high measurement data update rates for reasonable system costs. This makes the six-port architecture a promising candidate for industrial metrology.

“…These parameters have been used to calculate the maximum forces, which can be applied with this chuck jaw. Furthermore, the maximum change in length by the maximum force at the chuck jaw is needed in order to select the strain gauge [6]. The maximum change in length ∆L of the strain gauge has been calculated according to (1), (2), ( 3), (4):…”

In cutting procedures a possible reason for deviations from the predefined dimensions of the workpiece are deformations caused by the clamping. The deviations are usually measured after process using for example a coordinate measuring machine (CMM). It would be very much advantage to detect such deformations in process. Then, it could be possible to avoid, compensate or repair them before finishing. In the present work, four strain gauges have been applied into a four-jaw chuck in order to measure the clamping forces during milling and correlate them with deviations in the dimensions of the workpiece. A correlation between the clamping forces and deviations in the roundness of the workpiece has been verified. These investigations allow for the next step the development of an active clamping system for adaptive corrections during the cutting process.
