Let’s build the best_neighborhood for America’s greatest manufacturers, builders & creators here
For Aerospace, Defense, Auto, Ships, Chips, and everything that falls in between in America!
Of course that's your contention.
You're a first year manufacturing commentator. You just got finished readin' some Deloitte, National Institute of Manufacturing and journalists citing, let me guess -- US Bureau of Labor Statistics?
You're gonna be convinced of that 'til next

We have some surprises for industry, including the future we all see to solve America’s Skill Gap and return to building
Fate loves irony, our team generally hates digital training
But we knew this was the best starting point to help as many people as possible gain resources
We built ‘Co-Pilot’ to help anyone troubleshoot, tear stuff apart and get precise answers from millions of machine manuals,
Earlier than "FORTRAN" and "Graphical Interfaces", the "APT" Programming Language was created to provide instructions for the machine
"G Code" and "M Code" are two major components used to coordinate these 3D machine movements
This code was stored on Punched Tape
You'll then run a "Post Processor" to convert that neutral code from your CAM software, to the specific machine you have on hand
This allows for specific codes (as they vary by machine) to be added, as well as allows for tool path simulation
Completing your first CNC Program
In the 1940s, MIT & USAF backed inventor John Parsons to create "CNC" or "Computer Numerical Control"
Using Numerical Control, machine movements could be programmed and automated
This precision and speed allowed for unparalleled scale, revolutionizing manufacturing forever
Machining is the process of cutting a stock of material to create a "final shape"
Machining has allowed humanity to shape the atoms around us into the modern world
Manual machining allowed for steamboats, automobiles and aeroplanes
But were limited in speed and scale
These "Geometry" and "Motion" codes are still today the foundation of near all automated machinery
CNC Machines vary in complexity depending on the need of the finished part
Common examples include 3 and 5 axis machines
As you read this example NC Program, you'll begin to recognize a few simple commands
You'll also notice (M) "Motion Codes"
In the below code, the programmer asks the machine to (M6) grab a new cutter (T1) and (M3) spin it clockwise at (S) 5000 RPM
M06 T1
M03 S5000

Carbon Fiber can be a great entry point to join the fields.
We hope this post was helpful as a micro introduction!
As this topic is too large for a simple thread, we'd love to answer any questions you have about NC Programming
check comments for all of our favorite free resources to learn more!
If this thread was helpful, we greatly appreciate a share
American Manufacturing is misunderstood.
Vital to our Country? or Low Level Labor hated by society?
Reshoring or Offshoring? Declining or Booming?
No matter - it is one of America’s most powerful industries
Other G Codes allow for additional controls
G01 = "Linear Interpolation" (move to point), but allows for control of the "Feed Rate" or how fast the material is fed through the machine
Let's set a (F) "Feed Rate" of 200 inches per minute:
G01 X5 Y12 F200
Geometry codes simplify the math required to move the machine through points
G00 = "Rapid Positioning" (move to point), where the purpose is to reposition the machine as quickly as possible to an end point
A rapid positioning movement would look like:
G00 X5 Y0 Z-10
By creating a CAD file of your block of material (stock), and then placing your finished design on the inside (net part)
You can create tool paths that compute basic G & M codes that can be refined until you get a smooth operation
As well as more advanced tech such as Resin Transfer Molding, Tape Laying or Fiber Placement.
These methods aim to bring a level of autonomy & control
Each method has its pros and cons, depending on the application, budget, and required material properties.
Using these fundamentals, you are able to load your machine, workholding, block of material and all parameters into a CAD software (Computer Aided Design)
And write your first CAM program (Computer Aided Machining)
To write your first CNC Machine program

We know how difficult that is, because our team lived it.
Poor resources. Confusion. Anxiety. Lack of support. Overlooked and Underserved.
We asked ourselves -
Could there be a better way?
To understand how G & M Codes work, let's visualize a machine command
On this 3 axis (XYZ) machine, let's move the machine between two points in 3D Space, for example, we want to move the cutter "down by 10 units"
We would go from point A "X0 Y0 Z0"
To point B "X0 Y0 Z-10"
Aerospace, one of the sectors, today pays over 40% higher avg than National wages
And even with a shift to “Skills” > “Degrees”…
We are on track to over 3 million unfilled careers in just a few years
Why can’t we seem to get people to join?
Employers! Culture! Quality of Life. Low Pay. Benefits. Armchair Politicians & MBA grads. The new generation!
We’ve heard it all.
But what we never hear… is how hard it is for the average American to pursue the right career at companies like
@SpaceX
,
@Tesla
or
@Boeing

We deep dived this question and here’s what we’ve discovered, keep in mind we are centric to Aerospace & Defense at the moment -
Switching from Matrix Laboratory (subsequent, Simulink) to Python in Aerospace & Defense appears to have a few disadvantages for the enterprise.
Side quest: beat state sponsored T1K T0K at content. While their citizens fall in love with STEM, our people are fed trash.
We’ve been stock piling quite a lot of shots to feed our training engine, so we have plenty of ammo 🇺🇸

This makes us so happy
Let us know if we can contribute!! We have stockpiled tens of thousands of helpful industry resources. Open sourcing them soon
(new beautiful NextJS front end in progress to house them)
What if training for killer skills, wasn’t done on PowerPoint?
What if we gave people the tools they really needed?
What if we focused, on what would genuinely help?
In this “Skill-Focused” world, we got to work on making these easier to learn
Today, the leading method of manufacturing for Carbon Fiber is still ��Hand Layup” of carbon fiber “Laminates”, by composite technicians.
The most common methods include
1. Prepreg: Pre-impregnated sheets of carbon fiber are layered and then cured, often using autoclaves for
SR-71 for 1950s:
“It still looks like something from the future, even though it was designed back in the 1950s,” Peter Merlin, an aviation historian and author of “Design and Development of the Blackbird,”
NASA data sheet:
For those interested, C-RAM Or “Counter - Rockets, Artillery, Missiles” are Land Based Phalanx Weapon Systems (LBPWS) providing protection to warfighting personnel and high-value assets by detecting RAM launches and intercepting rounds in flight.

There are many benefits to the use of Carbon Fiber as a material:
5x Stronger than Aluminum, ~2x Stiffer and 1.5x Lighter and 5x Lighter than Steel.
It offers
- High Strength to Weight
- High Rigidity
- Corrosion Resistance
- Thermal Stability
- Fatigue Resistance

Journalists drastically -- Journalists 'drastically underestimate the impact of occupations predicated upon specializations, especially for developing wealth.'
You got that from Forbes, 'August 2016 “Manufacturing doesn’t pay nearly enough”,' front page, right? Yeah, I read

Technology’s rate of advancement has far outpaced our current systems
If we don’t create better systems to help more people join where it matters most, we let down more than just our future
A “Carbon Fiber” part is created in most industrial applications through “Layup”
A tooling fixture allows for “Plies” or sheets of fabric to be laid onto it
These carbon fiber sheets stack on top of each other to create a “laminate”

Our mission is to accelerate new skilled workforces to join us in building great futures
To unlock opportunities for all to participate in rewarding careers, without the debt and shortcomings that typically block so many

AFP & ATL have a place, but they introduce a great deal of complexities that need to be focused on.
HLU, RTM & Filament Winding can cover a great deal of part geometries and at rate.
Good for a well rounded engineer to have an understanding of all the tools!
