Profile of a Surface on a Honeycomb Composite Core
Profile of a Surface on a Honeycomb Composite Core
(OP)
Does the Profile of a Line or Surface have any special interpretaion when it comes to composite core. I have a coworker telling me that the profile of a line or surface tolerance can be measured at any point along the line/surface. This creates an issue with our attempt to define the profile of a cut on a piece of core.
In this situation with the honeycomb core, the cell diameter is 0.1875 in and the profile tolerance is .003.
If his definition is still the current one accepted even for composite cores then the .003 tolerance can not be held if the profile line/surface intersects any cells of the core, which is inevitible.
Does anyone know?
Thanks,

A profile tolerance can be measured at any point along the surface, and must pass at each and every point along the surface.
Is the profile being applied to the top surface, or to the profile of each honeycomb?

This question came about because we are trying to find a GDNT method to communicate the desired part edge. Of a feathered honeycomb core.
Any Ideas?

The top of your honeycomb is at least approximately a continuous surface. The non-presense of 95% of the material is irrelevant. A plate with 95% of the material removed by machining is precisely analagous.

Could you provide an image of the part you are talking about.

Although like others here, I question the fact that your trying to hold a known irregular surface to .003" We struggled with a profile of .010".
I too think the profile of a surface is possibly too stringent for this material and that profile of a line should suffice depending on the application. You simply want some level of assurance that the cut line is within a certain range, or if it's a mating surface then possibly a flatness callout is necessary. Hope this will help.
