This week I created a test plate with dichroic tiles arranged in different configurations to do some testing for a light and interactivity project (making a light fixture). I first created a file in vectorworks with pockets and cutouts for insetting tiles and letting light pass through. Then imported the file into mastercam, set up the pocket and profile parameters for a 1/8th inch bit, then generated g-code and saved it to a usb.

Next, I inserted the USB into the CNC, screwed my plate into the spoilboard, fit the bit into the collet, zeroed the axis, put the vacuum cover over the bit, and cut the piece.

The piece came out exactly as expected, although it had some burrs that needed to be sanded off. I always use the standard plywood feeds and speeds for PVC, I am sure I could get a cleaner finish tweaking the values a bit or using a finishing pass but it is really quick to sand. I was able to gain the information I was looking for for my light fixture design from the test piece.
