A parameter study of the eccentricity frequency and amplitude, and chip length effects on a machine tool with multiple boundaries

The parameter study of a machine-tool with interrupted cutting is completed for eccentricity frequency and amplitude. The effects with respect to chip length are also incorporated, such that comparisons of the parameter maps can be accomplished. Specific areas within the parameter maps are studied to explain the complicated motions within. In such a case, the switching characteristics are shown with respect to eccentricity frequency. The complexity of the periodic solution structure is discussed regarding the stability, in relation to the vector fields and mapping quantities. Furthermore, the traditional definition of a stability boundary is extended beyond existing literature. The most useful data is the overlay of the # of mappings and minimum switching force product record. These measures point out the extent and location of complexity in the machine-tool model studied herein.
