1. A fluid jet apparatus control system, comprising:
a controller clock;
at least one nontransitory processor-readable storage medium that stores at least one of processor-executable instructions or data; and
at least one processor communicably coupled to the at least one nontransitory processor-readable storage medium, in operation the at least one processor:
receives an initial motion program for a target object which is to be cut by a fluid jet apparatus;
receives a reference separation cut speed;
executes a motion program to cause the fluid jet apparatus to cut the target object according to the received initial motion program; and
from time-to-time during execution of the motion program,
autonomously receives at least one operational parameter of the fluid jet apparatus from at least one sensor;
autonomously determines a modified separation cut speed based at least in part on the received at least one operational parameter; and
autonomously adjusts a clock rate of the controller clock to cause the fluid jet apparatus to cut the target object based at least in part on the modified separation cut speed.
