Fig. 6 shows further comparisons with the semi-analytical model
considering the influence of the cutting conditions,such as the rake
angle γ0, on the chatter stability,It can be noted that the increase of γ0
can induces a decrease of the cutting forces which,in turn,implies an
increase of the critical width of cut,the cutting process becomes more
stable. In addition,the tendency is qualitatively in accordance with the
experimental results available in [13], [19] and [20].
