I can see the logic behind that... so upper segment located roughly, and bottom at MMC refines the located and allows us to create a hard gauge, that is located off upper segment.
Understood, so if MMC is applied on a Composite, both frames must posses it. Now how would a gauge to check a multi single segment work if you had the top frame at RFS and bottom at MMC. Do we just do the math as normal but use the bottom frame tolerance and make that the pin/hole size?
Youre correct, I was just reviewing a drawing with MMB and had that in my mind. Apologies hah. Fixed the tittle.
My question is directed to MMC application in second frame, but nothing on top frame.
Hi everyone,
I have a question regarding Composite/Multi Single Segment FCF and application of MMC. Are there any rules to this? How would it work if you had bottom frame at MMC but the top frame at RFS. Since top is locating it, and bottom refines the location. Thank you for any insight!
When you're mentioning "cool off" are you speaking between each operation? Per x amount of holes? I def see with my part having 33 mounting holes and doing all at same operation, the heat may build up.
Ghost,
good points regarding having restrained vs unrestrained condition. From what I saw, I do believe they restrain it during inspection, however it may not be to the same force as manufacturing. I will look at this.
Thanks for the input Dave,
It seems like any research I do it comes down to fixturing. I spoke with one our machinists and he actually suggested to have them do the "Ball Test" on the CNC machine. Which I may have to see if that was ever done at our vendor.
Hi everyone,
I am dealing with a small issue with one of our composite parts. For background, this is a composite enclosure that stores the aircraft evacuation system. This enclosure is off the wing, therefore it has awkward geometry it is 61" long and width of 45" tapering down to 20" overall...
