Method for machining composite blade in aircraft industry, involves calculating difference between measured profile and predetermined theoretical profile, and machining faces of central portion of blade based on difference

摘要

The method involves providing a fastening device (1) that comprises a clamp (10) to secure a foot (91) of a blade (90). Another clamp (20) is allowed to secure a head (98) of the blade. A measuring mechanism (30) is arranged on one side of the blade. A profile of one of a front face (951) and a back face (952) of a central portion (95) of the blade is measured with the measuring mechanism. Difference between the measured profile and a predetermined theoretical profile is calculated, and the faces are machined based on the difference. Independent claims are also included for the following: (1) a fastening device (2) a fastening and machining device assembly.
