Design and Development on Robot Workstation for Water-jet Cutting

High-pressure water-jet cutting machine combined with robot can cut workpieces with complicated shape accurately. The water-jet cutting workstation based on phased intensifier and industry robot with six degrees of freedom was designed, and the hardware composition and working principle of this workstation and phased intensifier are described. The robot controller accomplishes system administering and workpieces cutting, serving as the control kernel of the workstation. The phased intensifier employs a constant pressure variable capacity pump to provide power, compressed air to push pistons back, and a PLC to control working sequence of two pistons, which causing the structure of mechanism and control system to be simplified. This paper discusses the structure of cutting program and cutting process of car dash board. It is proved that this workstation work stably, which can meet cutting requirements of dash board.
