This Instructable will show you how to water jet a simple decorative sign out of fluted aluminum. First you must lay out the text you want to cut out in Corel Draw (or similar program). When you get the text layed out how you want it you can convert the text to curves and then edit the curves to be exactly how you want your sign cut out. I wanted my sign to be all one continuous piece, so I picked a font for my sign that was a cursive style with the letters overlapping. I deleted any of the lines from one letter that intersected with another letter using the virtual segment delete tool. This left me with a clean outer profile for the water jet path to follow. Then I exported these curves as a .DXF file and specified the R10 version.
Step 1: Opening the DXF and Autopathing in Flow Path Software
To set up the file for the water jet, I opened the .DXF in the Flow Path software. I then assigned my curves a speed of 80% and adjusted their position relative to the origin. Then I used the auto path function to generate the cut path of the water jet.
