The aim of this paper is to clarify experimentally the stability of regenerative chatter vibration in ball end milling. The validity of the proposed theory is also examined by systematic experiments. The results obtained are as follows. (1) It is seen from the cutting forces and photographs of machined surfaces that the chatter vibration occurs easily in the region where the instantaneous depth of cut is small. (2) The chatter stability in "downward cross-feed, up milling" is highest in comparison with other cutting modes. (3) In the case of "upward cross-feed, up milling", depth of cut hardly effects on the chatter stability, while large cross-feed heightens the chatter stability. (4) High inclination angle of workpiece results in low stability. (5) The chatter stability limits measured in experiments are in good agreement with the limits predicted in the theoretical analysis.
