Generally I've seen waterjetting quoted as having an accuracy of around +/-0.003", maybe 0.001" as a minimum, and that there is a significant taper of a few thousandths generated on the part (which can be reduced by taking more time). However, I have heard that teams make gearboxes from waterjetted plates, so I wan't exactly sure how accurate it really is.
Can somebody from a team who uses waterjetting comment on its accuracy and precision? I would prefer actual numbers, but pretty much anything would be good, as FRC use is probably different from other things.
