VERICUT在高速列车构架数控加工中的仿真研究与应用

The Simulation Research and Application of VERICUT in the Numerical Control Manufacturing Process of High-Speed Train Main-Frame

摘要: 加工仿真是对真实产品制造过程进行的虚拟仿真，其通过三维动态数字模型展现产品制造流程。本文利用VERICUT软件建立五面加工中心几何模型及运动学模型，并根据实际应用机床对配置的Siemens 840D数控系统进行功能扩充，并使用VERICUT软件建立加工刀具库。进而通过在VERICUT软件中建立虚拟机床模型，调用和修改CNC控制系统对高速列车构架加工进行仿真演示，从而便于观察加工刀具轨迹是否符合预期要求，从而验证整个加工程序的正确性。

Abstract: Machining simulation is one kind of the virtual simulation towards the real product manufacturing process. It could present the product manufacturing process based on the 3D dynamic digital model. This article set up the geometric model and Kinematic model for Five-sides Machining Center by VERICUT, and expanded the functions of Siemens 840D numerical control system based on the real applied machine tool. We also set up the machining tool library in VERICUT software. Then we set up the virtual machine tool model in VERICUT, invoked and modified the CNC system to present the machining process simulation demonstration towards the process of high-speed train main-frame. So we can observe whether the cutting tool path meets the expected requirements or not, then we can verify the whole manufacturing NC program.
