摘要
针对航空发动机整体叶轮零件的五轴数控加工问题,对工程实用五轴数控加工机床的空间构型进行了系统划分,将可以用于整体叶轮加工的五坐标数控加工机床划分为双摆头结构类型,双转台结构类型和摆头转(摆)台及单摆头单摆台结构类型,并对各种构型的五轴数控加工机床的坐标变换后处理过程进行了详细的推导。最后,提出了根据待加工整体叶轮的结构特点,对最适用五轴加工机床的选择的思路,并就整体叶轮构型与五轴加工机床选择进行了定性分析。
Aiming at problems of overall blisk parts for aircraft engines 5-axis CNC machining,the kinematics structures of 5-axis CNC machine tools were classified.Practical five-axis CNC machine tools can be used for the 5-axis NC machining of blisk machining,which is divided into 5-axis with dual rotary heads type of structure,5-axis with dual rotary tables type of structure and 5-axis with rotary head and table structure type.The coordinate transformation for each machine topology was developed.At last,based on the structural features of the blisk parts,the selection of machine tool structures for blisk machining was presented.
