Abstract
We have developed a new model for chip formation in machining which includes a mechanism for thermomechanical feedback. This leads to an interpretation of metal cutting as a process which is similar in many ways to an open chemical reactor. As the cutting speed is increased, there is a Hopf bifurcation, which explains the observed change from continuous to segmented chip formation.Keywords
