Machine Tool Vibration

In the machining of optical components truth-to-form and surface finish are of critical importance and the adverse effects of vibration must be avoided if satisfactory work is to be produced. This paper discusses the two basic types of vibration encountered in the use of machine tools - forced vibration and chatter, and the ways in which they can affect finished workpieces. Some of the techniques available for investigating and solving vibration problems on machine tools are described and some of the design principles to be considered in reducing the susceptibility of machine tools to vibration are discussed.
