More than a year ago there was a very long and interesting thread in this forum about the importance of deburring aircraft parts.

I did a search for subject titles of:

Sharp edges

with no results.  Surely someone here can provide the link to that thread.

I want to print it and show it to our new full time production deburr person and to the new one coming on-board in the near future as we gear up for production.  I think it will be a good morale booster and might make for some interesting conversation and tickle some good questions.

RE: deburring

If I remember correctly, the thread was in the form of a quiz, where the OP asked for reasons to deburr, and was to get back with his answer, but never did.  It was a long and interesting thread.  It may have been Thread404_35606, but that one is no longer available.

RE: deburring

I believe this is it:

RE: deburring

That was the one I was thinking of!  When is wktaylor going to give us his "long awaited answer"?

RE: deburring

Thanks Cory.  That is the one.

RE: deburring

I was just thinking about that thread.  Wil had to take off for awhile.  I think he may have forgotten about that thread.  I'll let him know we're looking for him.

RE: deburring

Hi all,

About the thread one thing was left out about rounding of the edges or chamfering. It was all about reducing drag resistance when it comes to i.e an external patch on a wing I think.


RE: deburring

The thread name was "Mental Challenge for Aero Engineers."

RE: deburring

Interesting thread.
My guess for wktaylor's poser:  The golf ball dimple effect on aerodynamics (reduced drag).
"Dimples on a golf ball create a thin turbulent boundary layer of air that clings to the ball’s surface. This allows the smoothly flowing air to follow the ball's surface a little farther around the back side of the ball, thereby decreasing the size of the wake. A dimpled ball thus has about half the drag of a smooth ball."

Note that golf ball dimples were invented by William Taylor - co-founder of the present surface metrology company Taylor Hobson Ltd.

RE: deburring

Quality of workmanship . . . . quality shows, as does the lack of it.
