| nmz787 | does anyone have an idea for how to sense the thickness of the bottom of a concave hole formed by drilling with a drill bit? | 07:15 |
| nmz787 | basically i have this problem where i need to drill until 15 or 20 microns of material remains, then transfer from the machine shop to an ion beam mill | 07:16 |
| nmz787 | if the material is too thick, the ion mill can't finish the pinhole | 07:16 |
| Sync_ | nmz787: how large of a hole? | 11:33 |
| Sync_ | if it is large enough I'd just used a dowel to measure the distance that is not concave and then measure the drill | 11:43 |
| Sync_ | because the tip of the drill is not going to change | 11:43 |
| hozer | what are you making? | 20:31 |
| azonenberg | hozer: sounds like TEM sample prep | 21:24 |
| nmz787 | azonenberg: i believe that's what it is | 21:47 |
| nmz787 | Sync_: i believe the drill bit is at most 2mm, but maybe 0.5mm... i didn't ask... the pinhol is around 10 or 15 microns wide | 21:49 |
| Sync_ | I'd use a pin to measure the depth | 22:22 |
