Abstract

High-speed precision hard cutting always causes vibratory motion, which has great influence on production efficiency, machining quality, machining environment, operating cost, machine tool life and cutting tool life. The dynamic model is established that is about flutter system of external circular finish turning recycled hardened steel; the limit of hard cutting system stability is analyzed, and the limit of hard cutting system stability can be predicted with numerical simulation in Matlab; with the larger corner radius change and the more the hardness of workpieces increases, the more the maximal stabile cutting width reduces. Hardened steel GCr15 is cut in different cutting condition with PCBN tools, the result obtained by the method coincides with the actual result. So, with selecting cutting parameters through the method, it is ensured that the cutting proceeds in the stable region throughout.
