Abstract: PURPOSE: A system for securing cutting force of a water jet cutting system is provided to analyze effects influenced on flux conditions of a nozzle by analyzing relation between pressure distribution of the system and pump pressure. CONSTITUTION: Friction and shape loss of pipe lines are analyzed by a characteristic curve method formed by using a mass conservation equation and a momentum conservation equation of the flow. As a result, a system for securing cutting force of a water jet cutting system estimates the effect for both pipe elements and the degree of pressure drop changed according to the time, analyzes excessive pressure change formed by an operation condition such as the opening and closing of a valve, and accordingly provides reference pressure of a design to keep structural integrity of the whole system.
