“…However, this introduces new problems [ 4 , 5 , 6 ]. Among them, the solution of the tool vibration problem is particularly urgent, as it has a great potential to harm the tool life and workpiece machining accuracy, which is one of the basic problems restricting the improvement of machining efficiency and machining accuracy in micro-milling [ 7 , 8 ], The tool displacement variation at ultra-high speed can be more than 15 microns because of radial throw and other comprehensive effects [ 9 ]. In general, the establishment of a frequency response model of the tooltip or the online monitoring of tool vibration is considered to be the preliminary foundation for mastering the vibration of micro-milling tools [ 10 ].…”

“…XU Jinkai [ 35 ] proposed a three-dimensional pose reconstruction method based on the depth of field of the micro-milling tool. A non-contact, single-sensor system and a signal processing algorithm were presented by Robert Kuschmierz for vibrational behavior measurements [ 8 ]. However, because a large number of lenses were used, the measurement system was more complicated.…”

The vibration of the micro-milling tool presents a significant chaotic vibration phenomenon, which has a great influence on the tool life and part machining precision, and is one of the basic problems restricting the improvement of machining efficiency and machining accuracy in micro-milling. To overcome the difficulty of the traditional vibration measurement method with the online measurement of micro-milling tool multi-dimensional vibration, a three-dimensional (3D) measurement method of the micro-milling tool is proposed based on multi-fiber array coding, which converts the tool space motion into a decoding process of the optical coding array employing the tool modulating the multi-fiber array encoding. A 6 × 6 optical fiber array was designed, and a 3D motion platform for micro-milling tools was built to verify the characteristics of the optical fiber measurement system. The measurement results show that the measuring accuracy of the system reached 1 µm, and the maximum linear error in x-, y-, and z-direction are 1.5%, 2.58%, and 2.43%, respectively; the tool space motion position measurement results show that the maximum measurement error of the measuring system was 3.4%. The designed system has unique coding characteristics for the tool position in the space of 100 µm3. It provides a new idea and realization means for the online vibration measurement of micro-milling tools.
