COMPENSATION FOR A FLUID JET APPARATUS

摘要

A system and method for positioning a fluid stream for cutting a double contour workpiece includes a compensation module (113) configured to receive 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 during cutting and configured to provide as an output a modified contour path of said at least five degrees of freedom based on Kerf compensation errors. A motion controller (148) is adapted to receive the modified contour path of said at least five degrees of freedom and the velocity and is configured to provide control signals. A positioner (104) is configured to receive the control signals and position a fluid stream adjacent the workpiece accordingly.
