In order to drill holes with large length-to-diameter ratio without compromising in surface finish or straightness of the holes, Boring Trepanning Association (BTA) deep hole drilling method was developed. The detrimental effect of vibration amplitude on the surface finish of drilled holes is well known. Present work attempts to provide a simple model to predict vibration amplitude during a typical deep hole drilling operation. The experimentally measured vibration displacement amplitude is used to develop a simple analytical model based on the theory of un-damped vibration for a single degree freedom system. The magnitude of vibration is measured by accelerometers placed at two different locations of machine frame during deep hole drilling operation of high alloy steel using 125 mm diameter BTA cutting tool. An analytical model is used to validate experimental results calculated by using FFT. The experimental data is found to fit satisfactorily with the predictions of the analytical model. |
