Modeling of Coordinate Measuring Geometrical Parameters Form and Location Complexity Profile of Compressor Blade GTE

摘要

The study provides a method developed process modeling coordinate measurements of geometrical parameters of shape deviations and location complex profile. We investigate deviations shape and location of a series of compressor blades of the second stage Engine brand manufactured NC technology manual polishing. Estimated uncertainty of measurement error and geometrical parameters considered blades using the most commonly used algorithm for measuring the radius compensation tip by calculating the point of tangency along the normal to the measured nominal point.
