Abstract: It was found that when aluminium alloys were cut orthogonally at a low speed, a stable built-up edge was formed and it stuck to the tool face ; the built-up edge was not fallen off but stuck to the tool while the cutting was in progress and the built-up edge participated in the cutting. In this report, facing tests and turning tests on commercial aluminium alloys were performed to make clear whether the stabilized built-up edge mainteined the stability or the falling off and formation were repeated. As the result of this study, the built-up edge which was stable in a very low speed range was found to show an unstable behavior of formation and falling off as the cutting speed was increased. When the cutting speed was low, the variation period was long. The period became longer as the cutting speed was increased. In the experimental speed range, the change was continuous. The cutting temperature varied during the varying cycle of cutting force. It gave important clues to understanding the behavior of built-up edges.
