This paper deals with the regenerative chatter vibration in a straight tool with an asymmetric cutting edge. The vibratory energy of the cutting tool is consumed by the interference effect between the tool flank and workpiece surface, judging from the vibratory loop configuration of the cutting edge and the effective relief angle variation during vibration. Regenerative chatter vibration of straight tools with an asymmetric cutting edge is excited by the regenerative effect of chatter marks. This is confirmed by the dynamic cutting force simulation, where the specific cutting force, shear angle and friction angle on the rake face of the cutting tool are treated as functions of cutting depth variation. As a result, the vibration energy supply is ascertained for the vibratory loop observed experimentally by this simulation.
