An Analytical Study of the Effect of Fluid Flow on Damping Characteristics in Deep Drilling
Keywords:
drilling, chatter, chatter suppression, fluid, damping.Abstract
In this study a new method for suppression of chatter vibration in deep drilling based on the model previously provided by authors [Mehrabadi et al., International Journal of Machine Tools and Manufacture 49.12 (2009): 939-946] is discussed. The study showed that the application of the fluid flow would improve the damping characteristic of the drill bit. Some of the advantages of this method are: (i) being simple and low cost in construction, (ii) easy to assemble, and (iii) elimination of the need to adjust damping characteristic of the suppression method. In this research investigation, it is shown that by introducing a Stokes flow around the drill bit contained in a jacket, asymptotic border line of stability could be raised drastically while frequency of the chatter does not vary dramatically.
