Can anyone point me in the right direction for information on waterjet machines. Also, does anyone know if you can machine bevels and chamfers with a waterjet machine.


Thanks

Not sure where to look, but I'm sure a search on google will find some good results.

Bevels, chamfers cannot be done on water jet. It's very simular to laser jet, in that it is 2 dimensional. (Unless they've come out with a rotating head, but it doesn't seem feasable.)

I read of recent developments in waterjet that claimed a breakthrough in speed and accuracy was being attained because they were slightly tilting the water jet to reduce the lag effect of the lower end of the stream. But as far as I know, this was not being carried to the extremes we might call bevelling. There is always the problem of deflection of the stream when hitting a surface at a significant angle. But, who knows, they may have figured out something for that, too.

What do you guys think about this? I found this on some more intense searching with google.

I guess you don't want to goof up programming that one, or it'll cut right through the door, and the guy standing beside it, and lop the pendant off on the floor :D

Guys i e-mail these posts to a guy i know that does waterjet cutting.......

This may explain a little more. It seems the part being cut would lie inside a box. hmmm.....

At last! a subject I know something about
Bevels and chamfers are possible on a waterjet machine. On our machine which is only 3-Axis I would use multiple setups if the chamfer was in more than one axis. but there are 5 axis machines which are more than capable of performing this.
Yes there is some deflection of the jet on initial piercing but once it is through,it's easy. I have cut many different materials on my machine, and I'm still learning. You should see it cut foam!!
Any more questions and i'll try to help,

P.S.
Try http://www.waterjet.se/
We have one of their machines, and it's really good!

They are a waterjet shop in my area. They have alot of info on there site. I toured their facility through SME and boy do they know waterjet. They can do some truelly amazing things with their multi axis machines.

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.
