Clock Face "VeneeredPMMA" cnc

thingiverse

After creating the wall clock "Gorgeous Gorges," I started thinking about making another multilayered design that would take full advantage of the depth of cut. A donor had given me a few sheets of 15 mm acrylic glass, and it occurred to me that applying thin veneer to the surface and cutting the numbers with a very fine end mill could result in an impressive look. I realized that a little lighting would be necessary if the clock is not placed on the windowsill, so I added LED strips. Gluing wood to acrylic glass worked quite well using 30-minute epoxy. Then, I engraved the numbers with a 1.2 mm spiral-toothed endmill, cutting only through the veneer and leaving the acrylic glass nearly untouched. It was a relief that the counters did not come loose during this process. To prevent damage to the veneer, I also engraved the circle of the outer perimeter. Cutting the acrylic glass requires distinct parameters: it must be cut quickly while maintaining a shallow depth. My Sorotec Basicline can handle this task with ease. A 4 mm single-flute endmill had enough reach to cut through the glass. After completing this step, I flipped the piece over to create the recess for the clockwork and LED strip.
