ABSTRACT: In order to meet increasing demand for
higher productivity and flexibility, recently many kinds of multi-functional machine
tools, which are capable of multiple machining functions or different kinds of
machining processes on one machine, have been developed and widely used in
manufacturing industries. In this study, a multi-functional turning lathe,
which has two spindles and two turrets so that multiple turning operations and
various machining processes could be performed simultaneously, has been
developed. Furthermore, the equations of correlation between whole responses
and cross responses of the two spindles have been derived to examine to what
extent the two spindles affect each other’s vibrations.
