Claim 13:
14. A method for operating an abrasive waterjet system, the method further comprising:
supplying pressurized liquid to a jet-forming orifice of a cutting head of the abrasive waterjet system;
forming a jet from the pressurized liquid at the jet-forming orifice;
passing the jet through a mixing chamber of the cutting head while the mixing chamber contains slurry including abrasive material and liquid, wherein passing the jet through the mixing chamber causes abrasive material to become entrained in the impacting the jet against a workpiece to alter the workpiece;
diffusing the jet in a catcher of the abrasive waterjet system;
collecting slurry including abrasive material and liquid from the catcher;
flowing the slurry collected from the catcher into the mixing chamber;
detecting a concentration of abrasive material in the slurry collected from the catcher; and
automatically adjusting a rate of movement of the cutting head at least partially in response to the detected concentration.
