Abstract:
1. A method for positioning a fluid stream for cutting a double contour workpiece, the system comprising: providing information regarding a contour path in at least five degrees of freedom for cutting the double contour workpiece and a velocity of movement of the fluid stream relative to a surface of the workpiece during cutting to a computing device; determining with a computing device a modified contour path of said at least five degrees of freedom based on Kerf compensation errors comprising a Kerf width, a Kerf angle and a Kerf lag and the velocity of movement of the fluid stream relative to the surface of the workpiece; receiving the modified contour path of said at least five degrees of freedom and the velocity of movement of the fluid stream relative to the surface of the workpiece at a motion controller; and outputting control signals from the motion controller to manipulate the fluid stream adjacent the workpiece such that the fluid stream is substantially orthogonal to a surface of the workpiece along the entire contour path.
