- In metal cutting, spindle speed optimization for process stability is one example of action that may reduceproduction time and increase process reliability. For process stability, it is crucial to avoid regenerativevibrations and thereby enable larger cutting depth, with higher material removal rate as benefit. A spindlespeed optimization is usually based on the machine tool and cutting tool assembly’s frequency response atthe tool-tip. This is normally obtained by dynamic testing of the full assembly. In this paper we use areceptance coupling technique to reduce testing time by synthesizing the frequency response displacementfunction of the system. The method utilizes test data of the machine tool with an inserted blank tooltogether with a finite element representation of the real cutting tool. The coupling is made via a state spacecoupling technique. Comparisons are made with data from full system tests and a stability prediction isdemonstrated.
