中文摘要:
      为研究常见的耐磨和难加工材料GCr15钢的硬切削性能,利用Deform 3D对GCr15钢的导电加热切削过程进行有限元仿真;建立有限元模型,在切削参数一定的情况下,分析加热电流对刀具磨损深度、刀具主切削力,以及刀-屑接触区温度的影响。试验结果表明:刀具磨损深度随着加热电流的增加先逐渐增加然后逐渐减小,当加热电流达到一定值时刀具磨损深度锐减;随着加热电流的增加,刀具的主切削力逐渐减小,特别是当加热电流达到一定值时,主切削力开始明显减小,并呈现出线性下降趋势。
英文摘要:
      GCr15 steel is one of the common wear resisting and difficult processing materials,in order to study its hard cutting performance,its electric hot machining process was simulated by the finite element simulation software Deform 3D.The finite element model (FEM) of electric hot machining process of GCr15 steel was built,and the influence of heating current on the wear depth of tool,the main cutting force,and the tool chip contact zone temperature was analyzed under the condition of limited cutting parameter.Experimental results show that the tool wear depth is increased gradually and then decreased with the increasing of heating current.The wear depth is reduced sharply when the heating current reaches a certain value.With the increasing of heating current,the main cutting force is decreased gradually.Especially when heating current reaches a certain value,the main cutting force is decreased obviously with linear decreasing trend.
