The effects of the roundness of the cutting edge and the depth of cut on the static and dynamic cutting forces are researched experimentally under the condition with a gradually increasing depth of cut. And the behavior of the chip flow is observed by the use of a high-speed camera. The following findings were obtained: (1) the static cutting force doesn't depend on the cutting condition, i.e., the cutting speed and the feed rate in the rubbing and the rubbing-cutting transition regions; (2) the flow of the chip is unstable in the rubbing-cutting transition region; (3) the amplitude of chatter vibration depends on the time when the tool passes through the rubbing-cutting transition region; and (4) this unstable behavior of the chip flow is one of the causes of the primary chatter vibration.
