Turbine Blade Fixture for Inspection and Grinding

fixture must not occlude the grinder or the laser, which scans the blade’s surface. The fixture must also be able to withstand grinding forces while staying within the 20 micron requirement. While this will presumably take a large amount of force at the base of the turbine blade, neither the blade nor the fixture may plastically deform.
