近年来,随着三座标测量机的不断发展和完善及我国对三座标测量机的不断引进,对汽轮机大叶片型线卡板的精密测量已达到了新的水平:特别是由于电子计算机的广泛使用和数控机床的大力推广,使得叶片型线卡板进入了数字化设计、数字化测量和数控加工的新阶段。那么对叶片型线卡板的测量是不是就没问题了呢?不是的,先进的现代化测量设备往往与我们传统的设计方法和加工方法之间存在着一些不协调的地方,需要我们在工作实践中不断地加以解决。
In recent years, with the continuous development and improvement of the three-coordinate measuring machine and the continuous introduction of the three-coordinate measuring machine in our country, the precision measurement of the large-blade type of the steam turbine has reached a new level: especially since the electronic computer The extensive use of CNC machine tools and the promotion, making the blade line card into the digital design, digital measurement and CNC machining of a new stage. Is not there any problem with the measurement of blade profile cards? No, modern, state-of-the-art measuring equipment often has some inconsistencies with our traditional design methods and processing methods and requires us to work in practice In the constant solution.
