| Abstract: | The double-frequency of machine tool chattering is explained and a non-linear model is developed. The relationship between the dynamic stability or chattering amplitude and the cutting parameters and the conditions for the appearance of double-frequency chattering are discussed. The distribution of instability lobes in the direction of spindle revolution in the stability chart are determined by the regularity of occurrence of double-frequency chattering. |
