✦ Synopsis
This paper introduces a methodology to evaluate and compare machine tool toolholder-spindle interfaces based on experimental and analytical finite element analysis results. This paper illustrates that the results generated from bench tests (an approach previously used for comparing different sets of interfaces) to characterize toolholder-spindle interfaces do not represent properly the interfaces in a machine tool spindle. The proposed methodology can help standardize the tests and/or the joint parameters required for evaluating, comparing, and selecting toolholder-spindle interfaces by modeling the machine tool spindle itself.
