Authors Abstract
Content
Increased demand for machining with higher material removal rates necessitates the use of higher rotational speeds and higher side loads during the cutting process. These new machining parameters manifest themselves as chronic degenerative problems with spindles and tool holder taper interfaces. Regenerative vibrations serve to complicate this condition and greatly contribute to the severity of this degenerative process. This paper describes solutions for these recent machining process problems to manufacturing engineers and machine tool builders. An overview of the complicated processes that cause vibration induced damage to machine tools is presented in simple terms. The objective is to give the reader a basic understanding of vibration induced machine damage, and several ways to combat this problem. A fresh look at the problems associated with higher rotational speeds, high side forces, and material removal rates, with knowledge of Finite Element Analysis and Vibration Analysis techniques can solve many machining production problems of recent years.
