I'm making a simple lattice based table.  I'm made several before.   10 slats required.  Each slat need it's end round over.

Clamped an strip of 18mm BB plywood to my CNC bed, then cut a pocket to place the thin strips in and clamp them down. That guaranteed the slats were perfectly aligned to the Y axis of my CNC.   

In the past I've made a pin fixture to slip the slats onto and use my disc sander to sand them round.  As the hole placement was critical I used the CNC to cut the bolt holes, so I figured I'd use the CNC to round the ends as well.  

 

 

 

Cool. Old adage, "work smarter, not harder" fits this scenario.

Before I retired from teaching, my CNCs were kept busy with mostly student project parts to either cut out or cut the joinery details on.  Since then my CNCs mainly get used for only the details on parts that I've made using other tools in my shop. Details that would take more trouble to jig up for or were almost impossible to do any other way. 

 These slats are a good example.  The holes in them needed precise positioning and of course the ends needed rounding over.  The slats themself were ripped using my table saw from a scrap of red oak that was already 3/4" thick.  Sliced it into 3/16" wide strips, then ran the strips through my drum sander to remove any blade burns or scars and get them to final thickness.  A good mental exercise to figure out the best strategy for clamping them onto the CNC bed and make sure that as the bit moved over the slats it wouldn't hit any clamps.
