Abstract:The method to measure the throat equivalent of turbine blades is introduced. Based on UG， an instrument for equivalent measurement during the manufacturing turbine blades is designed. The positioning error is analyzed when points are used to locate complex surfaces and the method to eliminate the location error is also used in the positioning and measuring error analysis and correction of the designed instrument.
Keywords:turbine blade; equivalent measurement; complex surface; positioning error
