Spindle speed variation method for regenerative machining chatter control
International Journal of Nanomanufacturing, 2009Among machining chatter control methods, spindle speed variation (SSV) method is certified as a feasible and effective way: machining chatter can be suppressed by continuously and periodically fluctuating the spindle speed of the machine tool. This paper presents a systematic stability analysis of SSV method for machining chatter suppression based on a

Compensation of progressive radial run-out in face-milling by spindle speed variation
International Journal of Machine Tools and Manufacture, 2000This paper investigates the use of spindle speed variation to compensate for progressive radial run-out in the face-milling process. Machine setup errors like spindle axis tilt, cutter axis tilt and cutter center offset result in radial and axial run-out on the inserts.

Application of continuous spindle speed variation for chatter avoidance in roughing milling
Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 2011This paper investigates the effectiveness of the continuous spindle speed variation (CSSV) technique as a chatter-suppression strategy in the milling process. For this purpose, a two-fold study was carried out: on the one hand, a simulation analysis, and on the other, experimental tests.

Stability analysis on spindle speed variation method for machining chatter suppression
International Journal of Machining and Machinability of Materials, 2009This paper presents a systematic stability analysis of spindle speed variation (SSV) method for machining chatter suppression based on a machining chatter model of non-linear delay differential equation. The theoretical results are verified by results of numerical simulations and experiments. Some important results are achieved: the stability increment

Stability Analysis of Machining with Spindle Speed Variation
Advanced Materials Research, 2011In this paper the chatter stability of turning and full-immersion milling operations with spindle speed variation is studied. We present a method to calculate the stability lobes in the limit of very low and very high frequencies of the delay modulation. These approximations help to classify the results of numerically exact methods, as for example semi-

Suppression of self-excited vibration by the spindle speed variation method
International Journal of Machine Tool Design and Research, 1984Abstract A method for the analysis of the influence of spindle speed variation on the course of self-excited vibration has been presented. Thisanalysis is based on the influence of self-frequency of self-excited vibration on the stability of machining, and dependence of this frequency on workpiece rotational speed.

Machine-Tool Chatter Suppression by Multi-Level Random Spindle Speed Variation
Manufacturing Science and Engineering, 1999Abstract This paper presents a new method for varying the spindle speed to suppress chatter in machining. The spindle speed is varied in pseudo-random fashion within the bandwidth of the spindle system. Both implementation issues and spindle system responses to such signals are investigated.

Software Spindle Speed Variation as Method for Chatter Suppression in Drilling
2019The spindle speed variation (SSV) method for chatter suppression in drilling was studied. The existing chatter suppression methods used at various types of metalworking, including the drilling process, were analyzed. The spindle speed variation method was described. The experimental setup, which consists of the measuring equipment and the cutting tool,
