Research of Blade Design Based on RE and RP

Taking a turbine blade as the research object,the paper expounds the concept of reverse engineering. It focuses on the Three Coordinate Measuring Machine( CMM) with reverse technology data collection of the blade,the free form curve and surface reconstruction,realizes the blade of complex curved surface design with using UG software. It piles up manufacturing application of Rapid Prototyping system of model, and finally works out samples. This process verifies the reverse technology and rapid prototyping technology in complex surface accuracy and practicality in the design. Building model is beneficial to image observation,to a great extent,shorten the product development design and the processing cycle.
