A STUDY ON CREATING STABILITY LOBE DIAGRAM BASED ON TOOL TIP DYNAMICS

Abstract

Creating stability lobe diagram has an important role in optimizing the maximum depth of cut at the highest available spindle speed without chatter. Thus, this study was carried out to determine the stability lobe diagram of a milling machine tool. Firstly, the dynamics of tool tip were investigated by impact tests that applied impulse loads and the signals then were obtained by using Metalmax^TM. The TXF^TM was utilized to achieve the modal parameters by using modal fit. Finally, a simulation was accomplished by using a Matlab^R program to carry out the stability lobe diagram with Fourier series approach. The result obtained from simulation agrees with that comes from the software.
