Dynamic Chatter Abstraction : A scalable technique for avoiding irrelevant distinctions during qualitative simulation
One of the major factors hindering the use of qualitative simulation techniques to reason about the behavior of complex dynamical systems is intractable branching due to a phenomenon called chatter. Chatter occurs when a variable's direction of change is constrained only by continuity within a region of the state space . This results in intractable, potentially infinite branching within the beh...
متن کاملPerturbation Analysis of Spindle Speed Variation in Machine Tool Chatter
Spindle speed variation has been shown to be an effective method for chatter control. In this paper, a single-degree-of-freedom regenerative type chatter equation is treated using perturbation methods. Rather than using the time coordinate, the angle of revolution is taken as the independent coordinate for maintaining a constant delay in the equations. The spindle speed is taken to be harmonica...
متن کاملExperimental investigation of the gyroscopic and rotary inertia effects on the chatter boundary in a milling process
Experimental examination of the gyroscopic and rotary inertia effects on the chatter boundary in a milling operation is the chief aim of this article. The equations of motion of the tool vibration are derived based on Timoshenko beam theory and Hamilton principle by considering gyroscopic moment, rotary inertia, velocity-dependent process damping and radial immersion effect. For a range of dept...
متن کاملExperimental Passive Suppression of the Regenerative Chatter Phenomenon by Variation of the Frequency and Amplitude of the Spindle Motor Excitation in Turning
The suppression of the regenerative chatter phenomenon in turning process via the variation of the frequency and amplitude of the spindle motor excitation is carried out in this research. A programmable inverter is employed for variable periodic excitation of the spindle motor. A set of turning experiments is designed and performed on a number of conical work pieces both in constant spindle spe...
