Dynamics analysis of cutting process of machine tool

摘要

The paper explores the dynamic performance of the process of machining metal by the method of computer simulation and numerical analysis. The results show that, when cutting force goes up from a small value to great one, the vibration of machining process in the feed direction appears as a stable periodic vibration, then a period doubling bifurcation, and at last a chaotic vibration. Anyway the vibration of machining process in cutting direction is always a stable periodic one.
