一种利用对刀仪检测汽轮机叶片汽道余量的方法
摘要：
一种利用对刀仪检测汽轮机叶片汽道余量的方法，本发明涉及一种检测汽轮机叶片汽道余量的方法。本发明是要解决叶片毛坯在五轴数控机床上加工余量不足，致使叶片汽道不能完全铣出来，进而报废的问题而提出了一种利用对刀仪检测汽轮机叶片汽道余量的方法。该方法通过步骤一、选择适当的对刀仪；步骤二、检测叶片汽道余量，包括（1）将待检测叶片装夹到安装有所述对刀仪的五轴数控机床上；（2）编制用于控制安装有所述对刀仪的五轴数控机床的检验程序；（3）利用上述检验程序驱动五轴数控机床动作；即完成了一种利用对刀仪检测汽轮机叶片汽道余量的方法等步骤完成的。本发明应用于检测汽轮机叶片汽道余量的方法。
摘要（英）：

The invention provides a method for detecting gas turbine blade gas passage surplus by utilizing a cutter setting instrument, and relates to the method for detecting the gas turbine blade gas passage surplus. The provided method for detecting the gas turbine blade gas passage surplus by utilizing the cutter setting instrument aims at solving problems that a blade gas passage cannot be completely milled caused by processing surplus insufficiency of a blade work-blank on a five-axis numerically-controlled machine tool. The method comprises the following steps: step one: the appropriate cutter setting instrument is selected; and step two: the blade gas passage surplus is detected, and detection comprises that (1) a blade to be detected is clamped on the five-axis numerically-controlled machine tool provided with the cutter setting instrument; (2) a detection program used for controlling the five-axis numerically-controlled machine tool provided with the cutter setting instrument is compiled; and (3) movement of the five-axis numerically-controlled machine tool is driven by utilizing the aforementioned detection program so that the steps of the method for detecting the gas turbine blade gas passage surplus by utilizing the cutter setting instrument are completed. The invention is applied to the method for detecting the gas turbine blade gas passage surplus.
