“…They observed the gain of stability as a direct effect, but not proportional to the cutting interruption degree. Palacios et al [60] combined a simulated annealing technique (SA) with numerical methods to find the optimal cutting conditions in turning operations. They applied this methodology when turning difficult-to-cut materials such as nickel-based superalloys leading to 100 times faster computational times.…”

The general trend towards lightweight components and stronger but difficult to machine materials leads to a higher probability of vibrations in machining systems. Amongst them, chatter vibrations are an old enemy for machinists with the most dramatic cases resulting in machine-tool failure, accelerated tool wear and tool breakage or part rejection due to unacceptable surface finish. To avoid vibrations, process designers tend to command conservative parameters limiting productivity. Among the different machining processes, turning is responsible of a great amount of the chip volume removed worldwide. This paper reports some of the main efforts from the scientific literature to predict stability and to avoid chatter with special emphasis on turning systems. There are different techniques and approaches to reduce and to avoid chatter effects. The objective of the paper is to summarize the current state of research in this hot topic, particularly (1) the mechanistic, analytical, and numerical methods for stability prediction in turning; (2) the available techniques for chatter detection and control; (3) the main active and passive techniques.

“…Based on the results obtained by Palacios et al (2018), the tool-holder have only one vibration mode with modal values of f = 1650 Hz, ζ = 0.0662 and m = 0.2866 kg. In addition, Palacios et al (2018) also presented in Figure 4 the cutting conditions that produce a stable, unfilled circles, and unstable, triangles, scenario.…”

Inconel is a hard-to-cut material that uses very low cutting speed. In turning operation added to the low cutting velocity, there is also a second limitation to productivity: chatter. In order to reduce chatter, the depth of cut is reduced and the material removal rate is lower. One option to avoid reducing the depth of cut is using vibration assistance machining. This paper presents a numerical investigation using 1D vibrations in the feed direction in order to reduce chatter in turning Inconel 718.

“…Since then, it has been widely used to solve combination optimization problem. The algorithm stimulates the process of heating up a solid to a high temperature followed by slow cooling [26][27][28][29][30][31]. As the temperature goes up, the particles of solid change into disordered state, causing an increase in internal energy.…”

In order to study the anti-shock performance of equipment under different working conditions, a hydraulic servo shaking table is used to replicate the desired motion with high fidelity. However, the sinusoidal acceleration response waveform is not a pure sinusoid due to the inherent nonlinearities within the system. The generating higher harmonic deteriorates the control performance and leads to system instability. To suppress the harmonic distortion and accurately estimate harmonic information, the harmonic estimation scheme based on simulated annealing algorithm is proposed. The sum of error square between actual value and estimated value is defined as the objective function. The amplitude and phase of each harmonic can be directly extracted when the objective function is minimized. Simulation and experimental results indicate that the proposed algorithm has good convergence performance and high estimation precision.
