Abstract: The invention features methods and apparatuses for altering a cutting operation during operation of the pressurized liquid jet cutting system. A pressurized liquid jet cutting system includes a pressurized fluid jet cutting head having a plurality of components. The cutting head further includes a sensor configured to sense an operating condition. The sensor transmits a value of the operating condition to a computing device, which alters a subsequent cutting operation. Further, the fluid jet cutting head is configured to work with a data storage mechanism and a reader, such that the data storage mechanism in contact with a body of the fluid jet cutting head is configured to communicate information to a reader of the pressurized liquid jet cutting system. The information is usable to determine a condition of replacement (e.g.
