随着计算机软件自动编程和仿真技术的发展,航空发动机制造技术进入了新时代。本文以典型航空发动机轴颈类零件半精加工工序为例,利用UG和Vericut软件进行车加工数控程序编制和仿真。针对航空发动机轴颈类零件的特点,总结了数控程序编制和仿真的过程,包括建立UG零件和毛坯模型、建立UGCAM模型、创建UGCAM刀具轨迹、UGCAM程序后置处理、建立Vericut仿真环境、数控程序的Vericut仿真与分析等环节,实现了两种软件在此类零件中高效、合理的应用。1.航空发动机轴颈类零件特点在航空燃气涡轮发动机中,轴类件有薄壁空心长轴、轴颈类轴、鼓筒类轴等。其中轴颈类轴分前
With the development of automatic programming and simulation technology of computer software, aeroengine manufacturing technology has entered a new era. In this paper, a typical aero-engine journal parts semi-finishing process, for example, the use of UG and Vericut software NC machining programming and simulation. Aiming at the characteristics of aeroengine journal parts, the process of compiling and simulating NC program is summarized, including the establishment of UG parts and blank model, the establishment of UGCAM model, the creation of UGCAM toolpath, the post-processing of UGCAM program, the establishment of Vericut simulation environment, Vericut simulation and analysis and other links, to achieve two kinds of software in such parts efficient and reasonable application. 1. Aeroengine journal parts features In the gas turbine engine, the shaft parts have thin-walled hollow long axis, journal shaft, drum shaft and so on. Including journals axis before
