Fluid jet cutting system
First Claim
1. A fluid jet cutting system, comprising:
- a nozzle;
a fluid communication line in fluid communication with said nozzle;
an abrasive feed line in communication with said nozzle; and
an abrasive purge gas line which is arranged so as to avoid fluid entry into the abrasive line.

Abstract
A method and apparatus for preventing water from entering the abrasive port of an entrained high pressure fluid jet nozzle and a method and apparatus for attaching the high pressure fluid jet nozzle to a hazardous duty robot. The invention includes the application of a positive air pressure to an abrasive line preferably during those times when there is insufficient vacuum generate by high pressure fluid being sent through the restricted orifice in the high pressure nozzle. The invention prevents clogging of a fluid jet cutting system during operation. The invention includes mounting a nozzle and/or visualization system to an expandable and contactable component such as a grasping device that allows for continued use of the expandable and contractible grasping unit. This includes, for example, a grasping device that is provided out the end of a movable robot arm and that allows for rotation of the grasping device.

40. A method of preventing a wetting of abrasive in an abrasive feed line leading to and opening into a nozzle in a fluid jet cutting system, comprising providing a pressurized gas state in said abrasive feed line which precludes liquid in-flow into said abrasive feed line.
- 41. A method of manipulating a nozzle in a fluid jet cutting system, comprising providing a nozzle on a grasping unit with expandable and retractable components which nozzle is positioned on an outer portion of said expandable and retractable components, and adjusting said components to achieve different radial locations in said nozzle and initiating and discontinuing fluid jet cutting flow at different radial locations.
-
42. A fluid jet cutting system comprising:
-
a fluid jet nozzle which includes an inlet for fluid and an inlet for abrasive;
a visualization system;
a multi-prong grasping assembly having a first and a second prong and means for adjusting the relative position of said prongs, and said visualization system supported on a first of said prongs and said nozzle on a second of said prongs.
