【摘要】 表面功能结构又称表面微观结构已经在改善材料加工性能方面,如表面摩擦性能和表面承载能力等,得到了广泛的认可,改善了刀具性能。通过设计带有微结构的刀具,用于改善钛合金的切削加工过程中刀具的磨损状况,延长刀具的使用寿命。并且在设计的过程中借助先进的有限元仿真软件Third wave AdvantEdge FEM进行仿真模拟。通过软件仿真替代大量的试切,避免试切过程中材料的浪费,更重要的是,可以在实际切削实验进行前对刀具的设计进行预测评价,节省了设计时间。更多还原

【Abstract】 Surface functional structure,which has been widely used in optimize the material processing performance like surface friction properties and surface bearing capacity,has been widely recognized and really improves the performance of tool.In this paper,one kind of surface functional structure tool aimed at reducing the wear condition and expanding tool’s life in titanium cutting processing has been designed.The advanced finite element simulation software—Third wave Advant Edge FEM has been used to simulate the cutting process in the design period.With the help of finite element simulation software,a lot of material can be saved,moreover it can anticipate the performance of designed tool before doing cutting experiment which can also save much time.更多还原
