Cutting & engraving EFIS panels

The first task for my Solidis CNC was the EFIS panel. Here I could get some lessons about cutting and engraving. Especially the engraving was very exciting because when you want to engrave your panel after it is already cut out and painted, the engraving has to be exactly at the place it has to be. So I designed a touch plate which I cut out from aluminum to calculate the orientation of the panel to the axis of the CNC.

The panel was painted with RAL 7011, engraved and covered with some coats of clear varnish. I used 3mm acrylic glass from Plexiglas (white WN070 GT and clear 0A000 GT). The cut out was done with a 2mm single flute bit and the engraving with a 30° engraving tool.

In the download package you will find the Estlcam files to cut out and engrave your own panel. As well as the dxf file to create your own tool pathes for your machine

    Hey Mickey, would it not be easier to engrave the buttons prior to cutting them out? If you painted the acyrilc area large enough for all the buttons you could position one panel and not have to zero out the Z axis for each button. Paint the panel, engrave it, cut it out, touch up the cut edges with paint.

      I was afraid that it wouldn’t look good, when I had to paint the sides by hand after the engraving. You can try to make the engraving and then glue up the three parts of the button, mask the engraved top and then spray it. But I don’t know if this would result in a visible transition at the top edges. Maybe this is worth a try when I have to make much more buttons. The CDU could be one of those projects.
