由于整体叶盘结构复杂,叶片型面为复杂自由曲面,扭曲度大,加工精度要求高,相邻叶片之间的通道深而窄、开敞性差,因此造成整体叶盘制造相对单叶片困难,相应也为其测量增加了难度。测量机对叶盘型面进行测量,首先要进行路径规划,路径规划的好坏决定CMM测量的效率和有效性。 Due to the complex structure of the whole leaf disk, the leaf profile is a complex freeform surface, the twist degree is large, the processing precision is high, the passage between adjacent leaves is deep and narrow, and the opening property is poor, The corresponding increase in the measurement of its difficulty. Measuring machine to the leaf disc surface measurement, the first path planning, path planning to determine the quality of CMM measurement of the efficiency and effectiveness.
