CNC Sunglasses- Cutting V. 0...

 I've started the cut after A LOT of tempering with settings

Anddddd the wood splintered so horribly that the CNC Mill stopped cutting. I can maybe use this for some.. uh... data collection? On to V... 1.

CNC Sunglasses- Setting Up

I've finally begun the complicated process of carving my sunglasses on the CNC mill!

I started by scaling the glasses in Maya, using ctrl t to view the dimensions in centimeters. It's roughly 17 cm across and half a centimeter thick.

I exported the file as a .stl for the CNC cutter to read

I needed a material for the first draft, and I didn't want to waste time carving a 2 x 4. Instead, I cut out 2 pieces of plywood a little larger than my sunglasses.

After tacking the pieces together with spray adhesive, I left them in a vice overnight. Each slab is about a quarter centimeter thick, so I glued them together to get a half centimeter of thickness.

Sunglasses Render 1

I wanted to preview the render, so i added a plane in the background, a directional light, and a spotlight. I didn't spend too much time on lighting but it still turned out good enough. I decided to use the arnold renderer so I added an arnold coloring to the glasses, but it turned out more gray than I like. I'm not to bothered though, because I'm really trying to carve these into reality on a CNC mill.

Sunglasses Part 10

I applied the white material and duplicated it to get a good idea of what the glasses will look like. I also added a hole to the side pieces for a wire to run through.

Sunglasses Step 9

After all the reworking on the front of the frame, the side piece came together very quickly. The shape matches the blueprint, and while the smoothed version needs work I like shape.

Sunglasses Step 8

I again duplicated the half, and merged together the frame looks great! I added white blinn, and the product looks exactly how I want it.

Sunglasses Step 7

 After some reorganization of edges the geometry became presentable, so I added some edge loops. The loops came on well and it looks pretty good smoothed.

Sunglasses Step 6

I deleted A TON of lines and tried to connect the inner circle to other points. I tried adding edge loops but they're running across weird places.

Sunglasses Step 5

I created a cylinder and used booleans-> difference to make the cut... after playing around with geometry and mesh-> cleanup I realize this is going to need reworking...

Sunglasses Step 4

I beveled the model and duplicated it and it looks pretty good smooth! But I forgot the holes for the lenses...

 Duplicated and flipped (I scaled the duplicate by -1 on the Z axis):

Sunglasses Step 3

I tried to convert everything to quads as is, but I got a lot of weird shapes. I did TONS of reworking trying to fix the geometry but it's still weird.

Step 2 rework

I tried to simplify the smoothed model but it didn't turn out the way i wanted it too, so I saved it as an alternate and back tracked.

Sunglasses Step 2

I tried to Smooth the rounded part and got some weird shading.

I proceeded to reconstruct the messy parts.

After everything, I noticed the back had horrible geometry, so I deleted it to start from scratch.

Sunglasses Step 1

I started with the bulky, rounded shape.

I recreated the round shape to flatten it, than used the Booleans->Union tool to connect the hexagon.

After connecting the shapes, I worked on connecting the geometry.

Blueprint

Illustrator mock-up over rough draft:

After finishing the first version of the blueprint, I've added simple shape guides to aid with Maya modeling. Blue portions represent initial cube polygons, and pink areas represent cylinders. In this particular model, the cylinders will turn out to be negative space.

Below are Snips of the blueprint before export, including a view of the layer division.
