基于UG和VERICUT软件的整体叶轮四轴数控加工与仿真
|
摘要
由于整体叶轮具有叶片薄而弯曲程度大、数目多和流道空间小等结构特点,在加工过程中,工件和刀具容易干涉、产生欠切和刀轨路径规划困难等问题。通过对整体叶轮结构的特征和加工的难点进行分析研究,合理规划整体叶轮四轴加工工艺。使用UG软件生成叶轮流道和叶片的刀具加工轨迹,经过后处理器转换为符合实际加工要求的数控代码。使用VERICUT软件构建整体叶轮实际加工所使用的四轴数控机床的仿真环境,通过对整个整体叶轮的加工过程进行模拟仿真,验证整体叶轮四轴数控加工程序的正确性。为整体叶轮加工效率和加工精度的提高,实现在四轴数控机床上的加工提供了实际参考。
The integral impeller has structure features of thin blade, great bending strain, large quantities and small passages,etc. Problem exists during machining,for example,workpieces and cutting tools easily affect each other,which results in insufficient cutting and a difficulty in tool path routing,etc. By analyzing and studying the structure features and machining difficulties in integral impeller,the article makes a rational plan for the four-axle integral impeller machining process. UG is used to generate the machining path of impeller passage and cutting tool.The path is converted to a NC code meeting the actual machining requirement via a postprocessor. VERICUT is used to establish the simulation environment for four-axle numeric control machining tool that is used for the actual integral impeller machining. By analog simulation of the machining process for the whole integral impeller,it can validate the accuracy in the four-axle numeric control machining procedure of integral impeller. The article provides practical references for improving the machining efficiency and accuracy of integral impeller,as well as for realizing machining via a four-axle numeric control machine tool.
