Blade is a key part that widely used in aero industry. Blade surface is designed by computing load of gas dynamics. In general, the profile of blade is non-regular free-form surface, which is formed by fitting several section curves, also called design curves. Working ability was decided by its geometric and size. Quality of profile affect second flow lost rate of engine and energy transfer rate. So measurement for turbine blade profile is very important. There is a variety of profile measuring techniques in application in the past, such as template profile method, automatic draw-curve method, projection method, electric sense method, coordinate measuring method. Recently, there are some new method for measurement of turbine blade profile, for example, machine vision measuring method, four coordinate laser measuring method and laser scan measuring method. Laser non-contact measurement for turbine blade profile is established based on coordinate measuring machine. The comparison of measured result with CMM shown an accuracy good enough for blade profile measurement. The system can be a useful tool for blade profile control during blade production process.
