“…In addition, error compensation techniques [11], structural and topology optimization of load-carrying components, i.e., basement and column, by minimizing the strain energy or maximizing the eigenvalues [12][13][14], are the strategies typically used to face the previously-exposed issues. Alongside them, Tuned Mass Dampers (TMDs) have found application in the robotics field as well [15][16][17][18], Multi-TMD applications can be found mainly for chatter mitigation [19][20][21] and to reduce vibrations of structures with varying dynamics [22]. After the first cutting test performed on the real prototype, it was quite evident how the high impulse forces arising from the electric motors excited the machine resonant frequencies, thus leading to unacceptable components quality.…”

In metal sheet processing for automotive application, it is crucial to guarantee high robot dynamics for reduced cycle times and adequate components accuracy to be competitive in the market. Since the two aspects are closely and inversely related, the problem becomes challenging. After the first cutting tests, the Cartesian Robot prototype displayed insufficient dimensional accuracy when undergoing high accelerations. The solution hereby proposed is the design of a Tuned Mass Damper (TMD), working in shear mode, to reduce the robot vibration amplitude. To this end, an initial assessment of the robot frequency response and natural frequencies was performed both by using a Finite Element (FE) model of the machine and experimentally. Further, frequency response analyses were carried out to evaluate the TMD effectiveness and to highlight possible criticalities from the manufacturing point of view. On a numerical level, the proposed design can damp the machine resonant frequencies, also showing a certain grade of tunability before operation and in-plane orientation insensitiveness thanks to the use of cylindrically shaped springs.

“…The effectiveness of Sims' method over classical Den Hartog's method has also been shown in chatter suppression in a boring bar [6,7]. In milling operations, passive dampers have been mostly employed on the workpieces to suppress chatter that occurs due to the thin-wall parts [8][9][10][11]. Moreover, researchers have investigated multiple TMDs [12,13], two degree-of-freedom TMDs [14,15], and nonlinear TMDs with a friction element [16] and a cubic stiffness [17] to increase chatter suppression performance of a single degree-of-freedom (SDOF) TMD in turning and milling operations.…”

“…Both, chatter 12 and forced vibrations 13 have been deeply analysed. Different vibration analysis have been focused on the tool-part system characterization, 14,15 on the tuning of machining process parameters, 16 on the implementation of active features [17][18][19] and on the passive damping elements integration. 20,21 Nevertheless, these developments are focused in the process stability rather than in the system flexibility for the clamping of diverse part references.…”
