Chatter vibration is apt to occur when machining thin-walled parts with insufficient rigidity. The harmful excitation of periodical cutting forces can be mitigated by enhancing the dynamic stiffness or increasing the damping of the part. A composite viscous damper including air damping and eddy current damping is designed, which can be attached on the thin-walled part by the vacuum. Based on the formulations of air damping and eddy current damping, the optimal equivalent viscous damping is derived for achieving the maximum critical depth of cut. Furthermore, the geometries of the damper are determined for damping a specific thin-walled part after investigating its relationship with viscous damping. The modal test indicates that the damper can suppress multiple modes of the cylindrical thin-walled part, and the amplitude of the first mode of the frequency response function (FRF) is reduced by 57%. The composite viscous damper is applied to suppress the chatter and resonant vibration of the thin-walled part during machining. Milling tests demonstrate that the machining vibration is reduced by 55% and 76% after employing single damper and four dampers, respectively.

“…Kolluru et al 11 designed tuned viscoelastic dampers to minimize the vibration of thin-walled casings. Yang et al 12 applied the VA to the turning tool, and proposed a parameter optimization method considering the background modes. However, the application of single-DOF VA is restricted with its narrow vibration suppression bandwidth.…”

In turning operations, vibration is a significant problem that leads to an imperfect surface, cutting tool damage, and unstable production. Vibration affects not only the workpiece’s surface quality, but also the cutting tool life, and ultimately the overall process cost. Since Shape Memory Alloys (SMA) has a very high vibration damping capacity, the effect of using TiNi3 alloy as the turning tool holder material is investigated in this paper. The tool holder vibrations are investigated analytically and numerically in both external and internal turning operations. The analytical study utilizes the Laplace Transformation Method to find the natural frequency and the beam’s displacement as a function of time and the longitudinal axis. The numerical study is performed using transient and Modal Analysis using ANSYS software. A comparison of the analytical and numerical results shows that they were very close to each other. The numerical study shows that TiNi3 alloy decreases vibration amplitude and acceleration for external and internal turning operations. It is shown that the use of TiNi3 alloy in the turning cutting tools decrease the vibration acceleration amplitudes by 43.1% and 40.2% for internal and external turning operations, respectively. Additional improvement in the performance of the internal turning cutting tool is achieved by presenting a new model of the boring bar that depends on the integrating of TiNi3 alloy and carbide material. Optimization of five steps is made to obtain the optimal design of the presented model. The new model shows that the optimized boring bar decreases the vibration acceleration by 60.2% compared to the commercial boring bar. Therefore we strongly recommend it for manufacturing turning tool holders.

“…Traditionally, milling tool is regarded as flexible with respect to the workpiece. 1 Most researchers try to construct the stability lobe diagram (SLD) and then select optional machining parameters to ensure chatter-free operations. The regeneration phenomenon, which is the major cause of the milling chatter, is modeled mathematically by delay differential equation (DDE) with infinite dimensional state space, but its stability condition cannot be given analytically.…”

Regenerative chatter can easily occur in the milling process of thin-walled workpiece due to the inherently low stiffness. This article aims to predict the stability of thin-walled workpiece in the milling process with a complete dynamic model. First, multiple structural modes of thin-walled workpiece are taken into consideration, and a complete dynamic model of thin-walled workpiece milling system is developed. Then, a numerical integration method is used to achieve the stability lobe diagrams of the milling system and identify the chatter frequency. Besides, the major structural mode, which is responsible for the occurrence of thin-walled workpiece chatter in the milling process, is predicted. A series of milling tests concerning a general cantilever plate are conducted, and the test results agree well with the predicted results, which shows the effectiveness of the proposed method. Finally, the effects of milling tool and structural modes on milling stability are discussed separately, which could provide theoretical basis for the dynamic modeling of thin-walled workpiece in milling process.
