“…In addition, The cutting states of case (1) and case (2) keep stable. The results of case (1) and case (2) show that a large rake angle and a small clearance angle lead to a high cutting stability [4] . In case (3), the maximum work displacement amplitude value is 55μm.…”

Abstract. This paper is armed at researching the suppression method of cutting chatter. The occurrence of chatter is strongly influenced by the tool geometry. In this paper, The numerical simulation results are in good agreement with the Experimental investigation results. The results show. Tool geometry is the first essential factor of the occurrence of cutting chatter. A large rake angle and a small clearance angle lead to a high cutting stability. A decrease in rake angle and an increase in clearance angle will greatly increase the degree of the cutting chatter and decrease the cutting stability.

“…Later, however, another chatter mechanism produced by friction was developed by Grabec [6]. This mechanism, called frictional chatter, can cause interesting phenomena such as deterministic chaos [6][7][8][9][10][11]. While the frictional mechanism is based on friction between the tool and the workpiece, the regenerative effect is related to the wavy workpiece surface generated by the previous cutting tooth pass.…”

The paper examines a nonlinear one-degree-offreedom model of the cutting process. The classical regenerative mechanism of chatter is enriched by an additional friction phenomenon which generates frictional chatter. Additionally, the nonlinear cubic stiffness of the tool is taken into account. The aim of the paper is to investigate interactions between regeneration and the frictional effect. The proposed model is solved by the multi-time scale method. The cutting process stability (trivial solution) is determined in order to produce stability lobe diagrams and determine the influence of friction on the process. Finally, the maps of chatter amplitudes are presented and new frictional stability lobe diagrams are proposed to analyse the influence of friction.

“…The regenerative chatter is one of the most common in the literature. However, Wiercigroch et al [2,3], Lipski et al [4], Rusinek et al [5,6] show that the frictional effect is also important because it can produce the so-called frictional (primary) chatter and can even lead to chaotic vibrations [7,8]. Chatter vibrations generated in cutting operations are undesired because they can deteriorate the surface of a finished product, shorten tool life or even destroy the tool or the work piece.…”

Abstract. This paper discusses the problem of stability in a milling process for titanium super-alloy Ti6242. The phenomenon of chatter vibration is analysed by the multiscale entropy method and Hurst exponent. Although this problem is often considered based on stability lobe diagrams, theoretical findings do not always agree with experimental results. First, a stability lobe diagram is created based on parameters determined by impact testing. Next, cutting forces are measured in an experiment where the axial cutting depth is gradually increased. Finally, the obtained experimental signals are investigated with respect to stability using the multiscale entropy method and Hurst exponent.
