Z 2 CNC: Dark Money; Black-Scholes

Production Log for "Black-Scholes", Coin1 of Dark Money, 

a Limited Edition Series of sculptures in Ebony, Graphite and Brass.

 

 2.85 in. diameter by 0.65 in. thick

Mexican Royal Ebony & 260 Brass

Stained with Liquid Graphite 

Sculpted in ZBrush4R8

Milled on a PocketNC v1

CAM Software Fusion360

Aluminum Mounting Plate by Randy Kopf

17hrs milling time

Smallest bit, Harvey#989725 / 0.025 in.

Each "Coin" in the Dark Money Series will have the same 

material / stock structure.

0.5in Royal Ebony

0.04in Brass Plate

0.25in Royal Ebony

 Wood being wood, it is less accurate (in terms of being square, flat and unwarped) than metal.

With multiple layers laminated together, and wooden Sacrifice Stock (pine) underneath,

there is a potential for error of 0.01in.

(Actually, the potential for error is a lot greater than that if you don't

pay serious attention to clamping everything when you glue, or screw mount)

0.01in doesn't sound like much unless your primary target is a brass plate 0.04in thick.

So I need to adjust every cut, per block, using MDI G-Code, altering my Z axis 

movements to make sure I just kiss the brass with a flat end mill. 

Then I know I will have enough remaining depth in the brass for the engraving

and I wont cut all the way through. 

All the other cuts conform to this alteration.

My first attempts at this were done with wood veneer rather than metal,

as I didn't want to risk the end mills on my learning curve. Various types of wood 

were tested as well. Below is Black Oak with Maple veneer.

Cutting too deep not only takes me through the veneer, but it brings the other 

geometry deeper with it, so those cavities are also cut into the veneer. 

(see below bottle)

 Once I know the exact depth of the brass plate, to 0.001 accuracy, all the other

cuts fall into place. There are 13 separate paths generated in Fusion360

that I use to cut "Black Scholes". This path below is called Adaptive Clearing,

designed to remove large amounts of material as fast as possible, 

so that the detail cuts are removing as little material as possible.

Bits Used;

 A 0.25in dia Flat End Mill is used to clear the stock of excess material.

Harvey#51908

A Tapered Ball End Mill with a 0.032in dia tip is used for Finishing the wood.

Bits&Bits#TEB10-32

A Helix Tapered Ball End Mill with a 0.025in dia tip is used to engrave the metal.

Harvey#989725

This is a Harvey#989715 @ 0.015in. I broke two of these in my original attempts 

to achieve the ultimate in detail, as that is the smallest bit I can find on planet Terra.

The total milling time is 17hrs, but its the last detailed engraving cut 

on the brass that takes 8 hrs.

Here you can also see why I am mounting my Ebony to the pine Sacrifice Stock.

It allows me to cut around the Ebony, cutting into the soft pine, 

without hitting the aluminum mounting plate.

The final step is to apply

Liquid Graphite to the finished wood.
Hand rubbing brings out detail.

Adhesives; 

Some are too fast, some are too thick, some are too brittle.

I found that a thick Cyanoacrylate type works best, 

otherwise, these two materials wont play nice together. 

 Protection;

It's loud. Particles and broken bits can fly.
Exotic wood dust can cause allergic reactions.

CNC Soap

My first finished product produced with a PocketNC.

It is basically a more limited approach to CNC,
as my original test model quickly reached the limitations of my
combined hardware, software, geometry choices.

I thought I was picking a simple shape, my Duael Designs Logo, 

which is a 3D yin & yang-esque swirl.

However, after many attempts, and help from Autodesk Fusion360 customer support, 

this geometry currently exceeds the ability of the code to "get under" the lip.

Figuring its just a matter of time until this changes, I altered my approach to objects that are flatter,

like a coin, and would allow me to concentrate on the other learning curves of CNC milling.

One limitation at the time I acquired this software was that I needed to convert my geometry to T-Spline geometry in Fusion360 before I could generate the cutting paths with CAM. 

The conversion from a ZBrush exported .stl files was problematic at best.

As of May '17, you can now import stl files directly in  Fusion360's CAM

 

Machinable Wax was used. It's a great alternative to metal of wood, its easy on your tools 

and it can be used in the "Lost Wax" process.

This will be used to create a mold for soap.

Limited Edition Print "Little Time"

Latest Limited Edition Print (Edition of 3)

available @ SaatchiArt

 

What does it take to make a Watch? Not the act, but the infrastructure, the society. Metallurgy, astronomy, design. These basic foundations took thousands of years to culminate in the knowledge which was capable of manufacturing a Time Piece. In 2017, the Doomsday Clock went to Two and one half minutes till Midnight, the shortest time on record.
