Abstract

The paper deals with the effect of chamfers on the tool edge on the chip formation process. It is found that both in continuous cutting and in the exit phase of interrupted cutting where chamfers are mostly used the chip formation process is not very different from that obtained with nonchamfered tools. A buildup forms on the chamfer which acts as if it replaces the missing part of the edge. However, the thrust force component increases strongly which should have a beneficial effect on chipping of the tool edge. On the other hand, it will probably worsen flank wear.
