System and method for tool point prediction using multi-component receptance coupling substructure analysis

A system for predicting a three component tool point response of a spindle-holder-tool assembly to be used for high-speed machining applications, the system comprising one or more processors and configured to:

• determine direct and cross displacement-to-force receptances of a standard holder clamped in the spindle based at least in part on received data;
• determine direct receptances at a free end of the standard holder based at least in part upon the determined direct and cross displacement-to-force receptances of the standard holder;
• 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, the decomposition based at least in part upon inverse receptance coupling;
• and
• determine a tool point response by coupling tool holder receptances and tool receptances to the spindle-holder base subassembly receptances.
