Abstract
Ths paper describes the first stage of a project to actively cancel vibration in
vertical milling machmes and thereby improve the work-piece surface finish.
Parallels are drawn between continuous methods of vibration modelling
structures, and digital methods that can be implemented in real-time. The timevariant
nature of machine structures when cutting led to an investigation of
adaptive digital filter algorithms. Results are shown for experiments carried out
with two adaptive schemes used for on-line model identification and control.
1 Introduction
The Precision Engineering Centre at the University of Huddersfield has been
working on the problem of error-compensation and avoidance for many years.
So far, systems have been designed to successfully correct static volumetric
errors [l] and also structural distorti
