The paper presents a developed 2D finite element model of peripheral milling process for determining the temperature distribution and temperature history.The work material is cast aluminum alloy A356 and its flow stress is taken as a function of strain,strain rate and temperature in order to reflect realistic behavior in machining process.Temperature-dependent material properties are also employed in the analysis.The chip separation is achieved by the adaptive remeshing strategy.From the simulation,a lot of information on peripheral milling process can be obtained; cutting force,cutting temperature,chip shape,temperature distribution,etc.The temperature history office machined layer can be reported by conducting a point tracking.The predicted temperature profile at conventional cutting speeds and high speed machining are obtained.The finite element model appears to be perfectly representative of peripheral milling process and can be used to predict instantaneous temperature profiles and temperature history into the depth of the workpiece.

一曲《长征组歌》唱遍中华大地。周恩来曾１７次观看过组歌演出，并针对一些向组歌作者大泼污水的心术不正之徒，愤慨指出：“他写的《长征组歌》，你们能写出来吗？‘毛主席用兵真如神’是神来之笔嘛！”日理万机的周恩来，能唱下全部组歌，连弥留之际，还提出再听一遍《长征组歌》的要求。 这位用组歌形式，将举世闻名的万里长征搬上艺术舞台的大手笔，并非舞文弄墨的专业作家，而是威名赫赫的江西兴国籍上将———肖华。
