SYSTEM AND METHOD FOR TOOL POINT PREDICTION USING MULTI-COMPONENT RECEPTANCE COUPLING SUBSTRUCTURE ANALYSIS

摘要

A method for predicting a tool point response of a spindle-holder-tool assembly to be used for high-speed machining applications is provided. The method includes determining direct and cross displacement-to-force receptances of a standard holder secured in the spindle based upon measurements of displacement-to-force taken at different rotating speeds of the spindle. The method also includes determining direct receptances at a free end of the standard holder based upon the determined direct and cross displacement-to-force receptances of the standard holder. Additionally, the method includes performing an inverse receptance coupling to simulate a decomposition of the standard holder into multiple subassemblies, the subassemblies including a spindle -holder base subassembly and an extended holder subassembly. The method further includes determining spindle-holder base subassembly receptances based upon the simulated decomposition of the standard holder.
