针对航空发动机叶片形状复杂、加工精度高的特点,在ACIS几何平台上采用截平面法进行刀轨规划,变步长法控制加工精度,刀轴矢量自动调整法避免干涉,反变形补偿法控制加工变形,实现了叶片主面及阻尼台无干涉加工,并开发了航空发动机叶片五轴铣削加工计算机辅助软件。与通用CAM软件相比,该软件具有针对性强、操作简单、走刀路径更优化、对阻尼台的加工处理更方便等优势。
In view of the complicated shape and high machining precision of aeroengine blades, the cutting plane plan is adopted on the ACIS geometric platform, the variable step size method is used to control the machining accuracy, the tool axis vector auto adjustment method is to avoid the interference and the anti-deformation compensation method is to control the machining Deformation, to achieve the blade main surface and damping Taiwan without interference processing, and the development of aero-engine blade five-axis milling computer aided software. Compared with general-purpose CAM software, this software has the advantages of strong pertinence, simple operation, more optimized path and more convenient processing for damping table.
