Patent ID: 8764382

Claim:
A method for forming a pressure measurement hole in a component, the component comprising a body having a surface that defines a body surface profile and a covering layer that defines a layer thickness, the method comprising the steps of: (i) forming a hole in the body that extends from the body surface; (ii) fitting an insert into the hole such that, when fitted in the hole, the insert protrudes from the body surface, the insert having a longitudinal passage; (iii) machining the protruding end of the insert to define an insert surface profile that is matched to the body surface profile and displaced from the body surface by a distance substantially equal to the layer thickness; (iv) inserting a blocking pin into the passage of the insert to seal the passage of the insert; (v) bonding the covering layer to the body surface in the region of the hole and insert; and (vi) removing the blocking pin from the insert.
