1. A fluid jet cutting system comprising:
a first abrasive feed container including a first vessel that encloses a first interior volume, the first interior volume at least partially occupied by dry abrasive with a first moisture content;
a second abrasive feed container including a second vessel that encloses a second interior volume, the second interior volume at least partially occupied by wet abrasive with a second moisture content that is higher than the first moisture content;
a cutting head having:
an orifice unit through which fluid passes to generate a fluid jet;
a mixing chamber downstream of the orifice unit through which the fluid jet passes, the mixing chamber communicatively coupled to the first abrasive feed container such that the dry abrasive has a first path from the first abrasive feed container to the mixing chamber where the dry abrasive is added to the fluid jet to form an abrasive fluid jet, and the mixing chamber communicatively coupled to the second abrasive feed container such that the wet abrasive has a second path from the second abrasive feed container to the mixing chamber where the wet abrasive is added to the fluid jet to form the abrasive fluid jet; and
an outlet though which the abrasive fluid jet exits the cutting head.
