基于DEFORM-3D的高速车削加工仿真

DEFORM-3D是应用有限元方法(FEM)分析三维复杂加工过程的模拟工具,它不仅鲁棒性好,而且易于使用.借助于该模拟分析环境,能够对切削过程中刀具几何参数、切削条件以及加工过程中的其他因素产生的影响进行研究.应用DEFORM自带的切削仿真模型,模拟高速车削加工中工件及刀具的温度分布、切屑流动、应力、应变和切削力等.模拟结果对减少产品试验、降低开发成本、缩短开发新产品及新工艺的时间等方面都具有重大意义.DEFORM-3D对于研究刀具几何模型、切屑形成以及切削参数控制的刀具制造者和使用者来说,是一个较理想的工具.

Finite element simulation of high-speed turning using DEFORM-3D

DEFORM-3D is a powerful robust simulation tool that uses the Finite Element Method(FEM)to analyze the three-dimensional complex machining processes. It provides a virtual testing environment in which engineers can study the influence of tool geometry,cutting conditions,and other factors on machining process performance.The high-opeed turning process modeled uses DEFORM.With the help of model,the turning cutting forces prediction and the temperature distribution in the work piece and cutting tool,chip flow,stress and force or power requirements are simulated.The result of the simulation is crucial meaning to reducing the need for production trials,lower development Costs and shorter lead times for new products and processes.DE-FORM-3D is an ideal tool for both cutting tool manufacturers and risers who wish to study the effects of insert geometry and cutting parameters on chip formation and control.
