Abstract: The invention relates to a machine (1) for fluid jet cutting of a workpiece (2), comprising a stand (4) with two essentially parallel guides (6, 8) at a distance from each other. A control unit (15) is configured to control the motion of the bar, the bar (14) carries one or more fluid jet cutting tools (16A-D). Each end of the bar are arranged to the guides via a first journal means (18A) and a second journal means (20A). The machine comprises a workpiece position measuring equipment (22x?, 22x?, 22x??) for sensing at least two reference positions (x?, x?, x??) of the workpiece (2), and the control unit (15) is configured to operate the motion of the bar (14) from the reference position values (x?, x?, x??) and other operational data. The invention also relates to a method for fluid jet cutting of a workpiece. The invention also relates to a computer program at a machine for fluid jet cutting of a workpiece.

Abstract: A fluid jet cutting system includes a control unit configured to control the motion of a fluid jet cutting head of the fluid jet cutting system relative a workpiece to be cut. The control unit is coupled to a fluid jet cutting head drive configured to incline the fluid jet cutting head relative a vertical line. The control unit is configured to operate the motion of the fluid jet cutting head from a predetermined inclination angle value and other operational data. The control unit is configured to automatically adapt the speed of the fluid jet cutting head in accordance with the predetermined inclination angle value. A method controls the motion of the fluid jet cutting head of the fluid jet cutting system, in which the control unit is configured to operate the motion of the fluid jet cutting head from a predetermined inclination angle value.
