Test system for adjusting machining range of e.g. blade retaining cell in turbine of jet engine in aeronautical field, has units to fix test pieces inserted into parallelepiped-shaped cuts to reproduce overall geometry of engine part

摘要

The system has parallelepiped-shaped cuts (2) formed along a cutting surface and positioned with respect to the position of elements of a part of a turbomachine, where the system is made of stainless steel or polyamide material. Fixation units i.e. threaded holes, fix test pieces representative of the elements and inserted into the cuts to reproduce the overall geometry of the engine part. The threaded holes are formed on bottom surfaces of the cuts. An independent claim is also included for a method for adjusting range of machining, by tribofinishing process, of elements of a turbomachine part.
