Summary: This paper proposes a method to suppress machining vibration of thin-walled workpieces by using magnetorheological (MR) dampers. A novel dynamic characteristic reconstruction strategy is proposed to improve the dynamic characteristics of the milling system and consider the effect of material removal. Control currents are calculated to offset the change of the damping and stiffness properties of the milling system.

Summary: A method is proposed to estimate the frequency responses of a workpiece with a fixture, and the receptance coupling method is extended to represent the dynamics of supporting fixtures. The method allows the compatible use of receptance of a fixture between workpieces, and cutting tests show that fixtures placed based on this method can suppress vibration.

Summary: This study investigates the use of fixture support in milling thin-walled workpieces, developing a model through experimental modal testing and finite element analysis. By adjusting the support force, the stability limit of thin-walled workpieces can be successfully improved, as verified through experimental tests and detailed signal comparisons. The proposed model accurately predicts chatter stability and draws important conclusions on the influence of fixture support forces.

Summary: In this study, a rapid method combining experimental measurements with the receptance coupling method was proposed to obtain time-varying modal parameters of the workpiece. The stability lobe diagrams (SLDs) calculated using the modal parameters were validated through immersion milling experiments. Additionally, two modifications, including additional cylinder masses and passive support, were explored to suppress chatter, with the modification of passive support producing better results.

Summary: This paper introduces a practical texture design on the tool flank face to suppress chatter vibration and flank adhesion. The proposed technique utilizes process damping phenomena for effective cutting, and new texture geometries are suggested to improve practical performance. Experimental results show that the textured tool is more stable, can increase cutting speed, reduce vibration amplitude, and decrease surface roughness after cutting.

Summary: This study proposes a digital twin model, consisting of two sub-models for cutting parameter optimization and chatter detection, to effectively suppress vibrations in thin-walled part milling. The digital twin model combines a real-time SLD and fusion analysis of multiple sensor signals to output optimized cutting parameters and avoid chatter. It also includes a monitoring window for visualizing the milling scenario and a database for recording manufacturing data.

Summary: This paper focuses on the stability analysis and chatter suppression of ultrasonic elliptical vibration milling of Ti-6Al-4V alloy. The study analyzes the stability of separated and unseparated ultrasonic elliptical vibration milling systems by simulating their tool tip motion paths. The effect of machining parameters on system stability is assessed, and the prediction results show that the stability region and axial depth of cut are influenced by the feed rate per tooth and ultrasonic frequency.

Summary: This paper presents a novel spindle speed variation strategy with piecewise characteristics, which effectively suppresses chatter. The influence of the strategy on cutting power is considered and some new conclusions are drawn. Additionally, recommendations are given for selecting the SSS amplitude ratio and frequency, and the strategy should be used in conjunction with chatter detection technology.
