Abstract: Chaos is one of the kinetic forms of nonlinear dynamic
system. As a new branch of theory of mechanical vibration, chaos
vibration is paid attention by lots of researchers. Machine tool-cutter-workpiece-fixture
is a complicated nonlinear dynamic system, there are lots of nonlinear
factors that influence on characteristics of system. Using the system’s
phase portraits’ Poincaré section and maximal Lyapunov exponent, chaos
in end-milling system is investigated.
Key words: Chaos Nonlinear dynamics system End-milling Vibration
