Abstract:
1. A computer-implemented method for predicting a three component tool point response of a spindle-holder-tool assembly to be used for high-speed machining applications, the method comprising: determining direct and cross displacement-to-force receptances of a standard holder clamped in the spindle; based at least in part upon the determined direct and cross displacement-to-force receptances, determining direct receptances at a free end of the standard holder; performing an inverse receptance coupling to simulate a decomposition of the standard holder into a plurality of subassemblies comprising a spindle-holder base subassembly and an extended standard holder subassembly to determine spindle-holder base subassembly receptances; and determining a tool point response by coupling tool holder receptances and tool receptances to the spindle-holder base subassembly receptances.
