Application of Spindle Speed Variation for Chatter Suppression in Turning
In the present paper the chatter instability of variable speed machining is studied. Though, there exist numerical methods for the computation of the stability lobes for variable speed machining, especially in turning processes the potential of an active spindle speed variation for chatter suppression is mostly unexploited. In the case of a slowly time-varying spindle speed, which is practicabl...
متن کاملMachine Tool Chatter Suppression Using Spindle Speed Variation
First part of the thesis deals with the dynamics and stability of nonlinear delay gyroscopic systems with periodically varying delay. The aim is to demonstrate that greater depths of cut may be achieved in a boring process (2 DOF) when the speed of the spindle is modulated sinusoidally instead of being kept constant. Since the variation of spindle speed is small and independent of the tool moti...
متن کاملPrediction of Chatter in CNC Machining based on Dynamic Cutting Force for Ball End Milling
This paper presents the suitable depth of cut, spindle speed and feed rate that will be chosen during machining. If thus parameters are not considered, this can provoke abnormal tool behavior such as chatter. Chatter will limit the tool life which only can be use for just a few times. To predict the chatter occurs, the parameters will be use are spindle speed, depth of cut and feed rate. CNC ma...
متن کاملComparison of Cutting Ceramics with Hard Metal Cutting Tools
Cutting ceramic tools are used especially at high cutting speeds in the machining process. The highly brittle type of structure and the tendency for cleavage (crack formation) are the infavorable properties of these materials, which keep their hardness at high temperatures. The hard metals are produced by sintering of the carbides such as whisker WC, TiC and TaC with the presence of Co as a bin...
متن کاملCutting Edge Technologies in Otology Field
With the recent breakthrough of science and technology, revolutionary changes are taking place in the medical environment. There has been much progress in the field of otology. Recently, endoscopic ear surgery technique has expanded the application and scope of the technique [1,2]. The development of information technology (IT) also affects medical education systems. Surgical training and medic...
