【摘要】：近年来,许多航空航天发动机轮盘类零件、燃气轮机叶片、飞机和火箭结构件对空间复杂曲面需求更为精确,使得五轴加工越来越重要,而且由于五轴机床自由度大,精度高,机床不能造成碰撞,所以五轴机床在执行切削加工之前需要做切削模拟试验。借此,本论文以虚拟五轴机床为选题,研究怎样运用Pro/ENGINEER,Power MILL和VERICUT三个软件来实现机床几何模型、运动模型的建立和加工过程仿真。本论文首先基于Pro/E软件,对Doosn_VMD630五轴机床进行了三维实体造型,构造并配置了其虚拟五轴机床模型。然后,对五轴机床仿真关键技术进行研究。例如五轴机床的初始化设置,如干涉检测、机床初始化位置、安装机床控制系统文件、机床运行轨迹等。同时建立了机床常用刀具库,构建了毛坯和夹具系统模块的模型,另外基于Doosn_VMD630五轴机床的虚拟加工系统平台也被构建出。最后,利用Doosn_VMD630五轴机床虚拟加工系统平台,结合Power MILL、VERICUT软件,成功完成了发动机叶轮的数控加工仿真,并将重心放置于对机床的碰撞、过切、加工质量的检验,使数控加工仿真过程成为可能,确保实际数控程序和加工过程的准确性、可操作性和安全性,最大程度上降低因数控程序的参数错误所带来的一些工件报废或机床碰撞磨损所带来的损失。本论文就叶轮加工实例对课题理论研究部分的内容进行了验证,证明将Pro/E、Power MILL与VERICUT相结合进行虚拟机床技术研究是一种可行的方法。
[Abstract]:In recent years, many aerospace engine wheel parts, gas turbine blades, aircraft and rocket components of space complex surface needs more precise, the five axis machining is more and more important, and the degree of freedom of five axis machine tool, precision machine tool can not be caused by the collision, so the five axis machine tool to do simulation experiment on cutting before performing machining. Taking this virtual five axis machine tool as a topic, this paper studies how to use Pro/ENGINEER, Power MILL and VERICUT three softwares to achieve machine tool geometry modeling, motion modeling and machining process simulation. In this paper, based on the Pro/E software, the 3D solid modeling of the Doosn_VMD630 five axis machine tool is carried out, and its virtual five axis machine tool model is constructed and configured. Then, the key technology of five axis machine tool simulation is studied. For example, the initialization of five axis machine tools, such as interference detection, machine tool initialization position, installation of machine tool control system files, machine tool track and so on. At the same time, a tool library for machine tools has been established, and a module of blank and fixture system modules has been built. Besides, a virtual machining system platform based on Doosn_VMD630 five axis machine tool has also been built. Finally, using the Doosn_VMD630 five axis machine tool virtual machining system platform, combined with Power MILL and VERICUT software, the successful completion of the simulation of NC machining of impeller, and the test center is placed in the collision, the machine over cutting and processing quality, the simulation of NC machining process possible, ensure the accuracy, the actual NC program and process the operability and safety, minimize artifacts caused by the parameters of NC program errors or scrap machine wear loss caused by collision. This paper verifies the contents of the theoretical research part of impeller processing, and proves that it is a feasible method to combine Pro/E, Power MILL and VERICUT for virtual machine technology research.
