This method first deduces an inclination error model in free-form surface measurements based on the non-contact laser triangulation principle. Then a four-coordinate measuring system was independently developed, a special fixture was designed according to the blade shape features, and a fast measurement of the blade features path was planned. Finally, by using the inclination error model for correction of acquired data, the measurement error that was caused by tilt form is compensated. As a result the measurement accuracy of the Laser Displacement Sensor was less than 10 \u03bcm. After the experimental verification, this method makes full use of optical non-contact measurement fast speed, high precision and wide measuring range of features. Using a standard gauge block as a measurement reference, the coordinate system conversion data is simple and practical. It not only improves the measurement accuracy of the blade surface, but also its measurement efficiency. Therefore, this method increases the value of the measurement of complex surfaces.<\/jats:p>","DOI":"10.3390\/s150612782","type":"journal-article","created":{"date-parts":[[2015,6,1]],"date-time":"2015-06-01T10:55:28Z","timestamp":1433156128000},"page":"12782-12801","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":37,"title":["A Rapid Method to Achieve Aero-Engine Blade Form Detection"],"prefix":"10.3390","volume":"15","author":[{"given":"Bin","family":"Sun","sequence":"first","affiliation":[{"name":"State Key Laboratory for Manufacturing Systems Engineering, Xi'an Jiaotong University,  Xi'an 710049, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bing","family":"Li","sequence":"additional","affiliation":[{"name":"State Key Laboratory for Manufacturing Systems Engineering, Xi'an Jiaotong University,  Xi'an 710049, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2015,6,1]]},"reference":[{"key":"ref_1","first-page":"2442","article-title":"CMM measuring data processing algorithms for blades about the contour measurement","volume":"34","author":"Lin","year":"2013","journal-title":"Chin.
