摘要
针对钛合金这类难加工材料插铣过程中切削区温度急剧增加的问题,为了预测切削区温度分布,本文采用热源法,建立插铣过程的数学模型,设定该模型为半无限大移动的带状热源,引入镜像热源作用,通过分析热源对工件上某点的作用,推导出该点的温度表达式,进而利用软件模拟出工件的温度分布图,最后将模拟数据和实验数据进行对比,误差在允许范围内,证明该模型的准确性和可靠性.
In order to solve the problem of the sharp increase of the temperature in the cutting zone in the process of inserting and milling titanium alloy,a mathematical model of the inserting and milling process is established by using the heat source method.The model is set as a semi-infinite large moving belt heat source,and the effect of the mirror heat source is introduced.By analyzing the effect of the heat source on a point on the workpiece,the temperature expression of the point is derived,and then the temperature distribution of the workpiece is simulated by using software.
