CNC router cut today

I cut this out of plywood for a test today. It's supposed to be cut in corrian and backlit making it look like a photo. The detail will be much better then.This is my Granddaughter. Eventually, I will have one of her and my Grandson in a lamp I will make. Probably will weld a stainless frame for the lithopanes. I'll post a photo when I get it done.

That is AWESOME Dan.The detail is well "AWESOME".Very cool.

Looks prety cool! What type of bit did you use?

10-25-2010, 08:29 PM
I used a 60 degree v bit with a 1/8" shank. I need to come up with a 1/16 tapered ball end mill with a 1/8" shank, it should make a smoother cut.

I will eventually be making this out of corian as a lithopane but am perfecting the process right now so I'm testing in plywood.
Here is the second test cut of my Grandaughter's image. I tweaked the program settings a bit and got much better resolution. The cut is in reverse, that is the higher parts are cut deeper. This will make the light areas lighter when backlit using corian. I need to get a 1/8th and 1/16" ball cutter for the final cut. I'm still using a v bit right now.

I can't wait to see the lamp.

Looks GREAT Dan. What is the process that you used to get to this point?

I used Vectric PhotoVCarve Keith. I made an oval around the main part of the image making it one color (red). In PhotoVCarve I set the red to be invisible to create the oval cutout. The program assigns the code based on the cutter and step over you enter. Pretty easy actually.
I have PhotoVCarve and Cut3D both from Vectric.

I got the new cutters and made a test in insulation foam that turned out quite well. I cut the back away (actually the front) to make it thinner to allow some backlight through and this is what I got. This is Styrofoam which doesnít pass the light very well. With corian or poly it will have much better image quality. Still, itís good enough to see what I am trying to do and the cut quality was super. The snot on the illuminated photos was from cutting the back away. The fuzziness is due to the low light allowed through the Styrofoam. The first photo is the actual router cut side, the others are with the foam flipped and backlit.

That's really cool Dan. Looks awesome. Makes me wanna make one for my newborn son.

Dan, Great work, wished I had your creativity, is there anyway to move up to a 1/4 shank or larger, it will take out a lot of the vibration when cuttting

I could get quarter inch bits but there really isn't much vibration as is. The feed is fairly slow and the material fairly soft so it's not really an issue. It takes about 3 hours between roughing and final cut to do the 4X5 cutout. The final cut step over is set to 14% for the .042" ball cutter.

It's gonna be nice.

I made a cutout in the poly material today and it looks pretty good. I didnít measure the thickness of the poly first so the initial cut was not deep enough. I compensated for this by cutting some of the backing off and sanding it smooth (you can see swirl marks from the sanding). I also regenerated the code and apparently had the step over set at 30% instead of the 14% I wanted so there are some lines in the image.
Still, the material was 1.99 so it isnít too expensive to experiment. I like it so far and think the next one will be the final one (I hope).

Looks great Gadget!
One thought is warping from the heat of the light bulb??

I plan on using a CFC for illumination Keith. That and an aluminum frame I think.

Gadget, that looks great, if I ever get my table finished, I'm going to have to attempt this.
