CNC Waterjet cutting instrument holes

Hey All,
Does anybody have any experience with getting a fiberglass instrument panel CNC cut with a waterjet (or any other CNC cutter for that matter)? I called several local shops and I couldn't get a definitive answer whether the waterjet will delaminate the composite around the cut holes or not.
I've previously cut with bi metal hole saws and the hole turned out quite a bit too large and I trust a robot to measure a lot more accurately than myself. I was also interested in laser CNC cutting, but I'm pretty sure that will burn the composite around the edges of the cuts.
Any input would be appreciated.

Thanks,

A CNC router should be a good option with fiberglass. You can run a 1/8" dia. cutter and do pretty well. There are quite a few sign shops that have small CNC routers & they might be a good resource. Depending on where you live, there may also be a fabrication co-op (Makerspace, etc.) that has the equipment to do this. No need to get exotic with lasers, etc.

After designing the panel on AutoCAD, I sent the .dwg file to Severn Valley Sailplanes in the UK. They made the fibreglass panel and CNC cut the holes.. They did an outstanding job, produced a delamination-free panel and shipped it to my door. If I was to try to find a negative it would be the wait before starting as they had a number of jobs on. But for experienced pros, definitely worth the wait.
