The shop next to me has water jet and here are some of the reasons they are staying 2 axis. The danger of an error that cuts something you don't want to. (Knew another shop with a water jet mounted on a robot arm. They never used it being afraid of killing someone next door with it.) The work they see requires a chamfer, not a full bevel and they are afraid of the part moving if they cut it out and then go in again to try to put on a chamfer. I guess you could do the chamfer first, then the verticle cut. Another reason is nesting. You'll really have to spread the parts out so the chamfer doesn't cut into the ajoining part. I'm machining a bunch of chamfers on water jet cut parts and both of us are happy. |
