Abstract
We have developed a new model for chip formation in machining which in cludes a mechanism for thermomechanical feedback. This leads to an int erpretation of metal cutting as a process which is similar in many way s to an open chemical reactor. As the cutting speed is increased, ther e is a Hopf bifurcation, which explains the observed change from conti nuous to segmented chip formation.
