This study is the first attempt to examine the thermal behavior of the system which consists of not only the tool but also the chip and the work in wood cutting. Workpieces of mizume (Betula grossa) were longitudinally and orthogonally cut with a few tools of different clearance and rake angles at a cutting speed of 500 mm/min and at some depths of cut. Closeup thermal images of the side face of the system were obtained using a thermographic device during cutting, and the thermal behavior for each type of chip formation, Type 0, I or II, was characterized.
