Re: 3D plasma/water-jet cutting

Seiman,
Thanks for the input. I know more about plasma cutting than water
jet and thought the surface might crreate a problem for the torch.

I hadn't thought of the fourth axis to tip the torch to keep it
normal to the surface. I could easily grind the opening to
compensate for the angle.

the torch it is not the right solution for 3D, but for water jet yes
3D might work only to cut 30 to 90 degree shape by turning the Z axis
front back right left.
