A couple of days ago I wrote about some of the details for the Revision "C" Frames, well there is more.... Revision "C" Frames are the first frames that have had the flat stock portions of the airframes cut with a "laser" process. Historically, we have used water jet as the primary machining method on flat stock with a few exceptions for parts that needed to be cut in a standard 3 axis mill; high stress area parts.
Water jetting, though great for many applications, leaves fine "stress risers" in the actual cut that has to be polished out or in the case of holes have to be subsequently precision reamed to final size. The holes were really not the problem because there is usually an AN Bolt associated with all 3/16" - 1/2" holes. The real problem that we were faced with were the edges of the parts. The difficulty is when you are left with an edge that now has to be "healed/polished" to remove the stress risers left in the actual edge of the part. The laser process has totally eliminated this issue and provides the look, fit and finish the G2's are known for. Categorically, the solution to the "edge" specification problem has now and forever more been addressed.
Now you can really "C" the quality....
Have a great weekend!
