Advanced Engineering

Depending upon when you catch us, yes, we can handle rush jobs. We often work over the holidays, Thanksgiving and even Christmas holidays. If you have a deadline – call us.

For years we have run three shifts of about 30 drafting folks per shift – allowing us to deliver work 3x faster, and seven days a week. Yes, we work 24/7, so you do not have to. The fun never stops here.

For 3D scanning, this is a different question. Because of the common setup work required, at best expect a 48-72 hour turn to be scanned. CAD or simulation services are in addition to that.

The Department of Homeland Security has identified 16 different infostructures:

1. Chemical Sector,
2. Commercial Facilities Sector,
3. Communications Sector,
4. Critical Manufacturing Sector,
5. Dams Sector,
6. Defense Industrial Base Sector,
7. Emergency Services Sector,
8. Energy Sector,
9. Financial Services Sector,
10. Food and Agriculture Sector,
11. Government Facilities Sector,
12. Healthcare and Public Health Sector,
13. Information Technology Sector,
14. Nuclear Reactors Materials and Waste Sector,
15. Transportation Systems Sector,
16. Water and Wastewater Systems Sector.

This is both Government and private sectors.

If you are in any of these industries, this directive is important to you for many reasons.  Do you know where your critical sections are? Are they well protected? Are there concerns for Hazmat, security clearance requirements, and other concerns?  Can you quickly rebuild what might be lost?

The important part of this means that critical infrastructure must be secure and able to withstand and rapidly recover from all hazards. Achieving this will require integration with the national preparedness system across prevention, protection, mitigation, response, and recovery.

Further details can be found at:  Government PPD-21

DHS – The National Infrastructure Protection Plan details:  The National Infrastructure Protection Plan

Industry specific plans:  2015 Industry specific PPD-21 plans

CAD / CAM Services provides PPD-21 for the following industries:  DHS – CAD / CAM Services

The Presidential Policy Directive 21 (PPD-21) is a Critical Infrastructure Protection and Resilience United States directive that aims to strengthen and secure the country’s critical infrastructure.The goal of this directive is to reduce vulnerabilities, identify and disrupt threats, minimize consequences and hasten response and recovery efforts related to critical infrastructure.

The directive defines resilience as the ability to prepare for and adapt to ever changing conditions, terrorists, and withstand and recover rapidly from disruptions. Resilience includes the ability to withstand and recover from deliberate attacks, accidents, or naturally occurring threats or incidents.

Yes we do, and have now for several years. In addition, we also support the industry specific plans as well.

Yes, we did back in 2008. We started using Cad Perfect™ back in the early 1990s because all of our customers wanted only real Cad Perfect™ work. Back then the buzz words were terms like machine ready, or DXF Traceover and others.

The problem is, nobody wanted that. They all wanted drawings and models that they did not have to touch. Everybody wanted drawings just as if they hand redrew the work themselves.

Thus, Cad / Cam Services™ was the first company to start offering ONLY Cad Perfect™ work.

It depends on the scope of work:

• 2D drawings – small quantity, normally 48 hours.  We have several customers where they contract to us, keeping 4-8 drafters busy full time.
• 3D models – complexity dependent, but smaller jobs in 2-3 days. Some models we have spent months on.  Again, we have several customers where they contract to us, keeping 6-10 3D CAD designers busy full time.

Simple jobs have a lead time of 48 hours. Larger projects are delivered and invoiced weekly.

Yes. NDAs are a common part of our business. All data is yours – not ours, and treated as proprietary data and not for public consumption or use. Probably 70% of our work is under NDA agreements. We can generally get these signed within the day.

Fill out our quote form, attach your files, or simply send us an email. Tell everything about your project, like the model purpose.

For smaller files < 15 MB you can simply email them to us.  For something larger, just drop them in any number of drop boxes like Dropbox, Google Drive, Microsoft OneDrive and others.  Or if you would like, just contact us for a private, hardened link.

It is fine to use most any time of compression such as  *.zip, *.rar, *.tar, *.7z, *.arc, *.LBR, and even *.iso images.

A direct email is [email protected]

We also use a hardened OwnCloud web file sharing platform for unlimited file transfers. We provide unique and very private Web Storage Portals, this also supports file syncing for extreme convenience for you. Because so much of our work is DOD or weapons design work, Security – and confidentiality is very important to us.

The more information we have, the more accurate the simulation results will be. It also depends on what type of simulation you want to run. For a simple FEA, we can run an accurate simulation with just a 3D CAD model and loading/force/pressure information that you want to simulate.

‍

Don’t have a 3D model? Not a problem, our team can make one for you from scratch, and then run an FEA on it.

‍

For a more detailed answer, a well-run FEA will need:

‍

• Material properties: What material is the part made out of? We can run different FEAs with different materials to help you pick the right one.

• Loading conditions: The size, location, and type of load you want to simulate.

• Bonding condition: How is the part held in place? Is it bolted, welded, or just sitting on a tabletop?

• A 3D model

• For other simulations: Please provide us with all thermal, dynamic, aero, and/or fluid flow information. Feel free to call us and we’ll walk you through what we need.

A Finite Element Analysis (FEA) is a form of non-destructive testing (NDT) that shows how your part reacts to real-world loading events. A common example is running an FEA on a support bracket. The FEA will give results showing how much the bracket deflects, how much reactive force is seen, and the kind of internal stresses the bracket experiences.

‍

FEA results will change dramatically based on the position and angle of the load, how much force is applied, the material properties of the part, and the design of the part itself.

‍

An FEA is used to optimize a part before manufacturing begins. It allows you to find weak points within your part or assembly, and it will predict a failure before you physically make anything. This gives you an opportunity to fine-tune each part to optimize its size, strength, and cost before you start producing it.

Yes, our team has license access to all of the major simulations on the market. Currently, we offer:

‍

• Finite Element Analysis (FEA) Simulation Services

• Computational Fluid Dynamics (CFD) Services

• Discrete Element Method (DEM) Simulations

• Testing Simulated Products

• Fiber-Based Material Simulations

• Geometric Optimization and Design Iteration

• Aero and Hydrodynamics Analysis

On our advanced computers, an FEA can be run in a matter of minutes. For incredibly detailed or complex FEAs, it might take a few hours or even overnight. Not to worry, we have dedicated workstations that just run FEAs 24/7, so you won’t have to wait long for the results.

Generally, an FEA is a good idea for any new part that you’re going to make. The FEA tells you whether or not your design is optimized, and it points out your part’s weak points (physically, not metaphorically). For structural or load-bearing parts, FEAs are often required by your industry standards. For any one-off parts or custom pieces, an FEA can keep your operation safer.

‍

Consult with our expert engineers to get a better understanding of whether or not your part needs an FEA, and let CAD/CAM Services handle the full project for you.

In our experience, FEAs are invaluable. Spending a few hours running a simulated FEA in the background can save you weeks of your time, thousands of dollars, and countless headaches. One time, we ran an FEA for a client and found that their base platform needed to be an extra 1/4” thick, or else it would have collapsed under the weight of the machinery and people. Without an FEA, the platform was likely to fail in real life, and risk people’s lives — but it was completely avoided with just a simple FEA. In this case, the original designer changed the thickness of their platform in CAD, created manufacturing drawings, and then sent the plans out for fabrication: a change that took a day of effort.

‍

An FEA can:

• Save you time

• Save on manufacturing costs

• Help you to avoid common design issues

• Optimize your part so you don’t overpay for manufacturing

• Keep your people safe

• Maximize power and fuel-efficiency

• Minimize drag

• Avoid thermal or physical failure

• Understand cyclic loading results

• Find the failure point of your designs

• Fine-tune your material selection

• Learn the physical limitations of each part

• Establish confidence in each design

• Be shared with stakeholders and investors to secure funding and buy-in

We have a minimum order fee $150.

We create 2D drawings from our 3D models for QC purposes. We follow aerospace standards and deliver ±.005” accuracy models for all projects.  All of our QC is done by a different person than the designer. On Catia work, we often use Q-Checker for Airbus.

First of all, we need to know the target CAD system and whether you have an existing  template, or set of CAD standards for this project.

The main question is the overall complexity. As each part and assembly consists of different features and elements the best way is to provide us with an example.  Again, a picture is worth a thousand words.

If you already have a model and need us to improve it or update it in any way we need to know which dimensions and features are critical and which can be modified to achieve your desired result.  Even a before and after example works very well. We started with x, and got to this CAD file.

We can also offer you better options if you provide us with the purpose of your project (demonstration, 3D printing, FEA Simulation, CNC manufacturing, etc.).  This helps us better refine the task.

Per hour. Hourly rate depends on what CAD software used and typically starts at $75 per hour.  In general, to make this process safer for you, we often provide you a fixed not to exceed the cost as well.  That way, you are protected from an open-ended PO. However, the reality is our fees are based on time. In addition, services in say Catia or NX are more expensive than say Solidworks. Or, simulation services are commonly done by real engineers.

We can provide ±.005” aerospace quality for every model. CT scanned parts can have even higher precision up to ±.001”.

We need to know whether you need your parts to be scanned by us. Or many times we can work with 3D scans provided by third-party companies.  The quality of the scan is everything in our business. Anyway, we strongly advise you to use us for both the scanning and the CAD conversion aspects.  That way, we can control the quality. Sometimes we receive poor quality scans which make it impossible to create truly Cad Perfect™ models for you.  By all means, send us a couple of even cell phone photos, and the rough size of the object.  Most of the time, this will provide us enough information to provide a real bid.

The price depends on the part complexity, size, as well as the target file parametres. We need to know whether you need full parametric models, and your desired accuracy. If you tell us the purpose of reverse-engineered models, we can often provide you with possible solutions. The target CAD software may change the price as well. This includes sophisticated Workstation add-on products such as Composites, Catia electrical wiring, mold design, and others.

It all depends on the part’s complexity, size and structure.

Depending on the situation we can offer you dissecting your part for scanning purposes or use CT if applicable.

For 3D scanning services our minimum order fee is $120.

• 4 to 400µm/voxel resolution
• Full inspection of large size samples
• Modular and micro-resolution capability
• 6 motion axis

Yes. This is one of CT scanners’ major points – to see into objects. This is the best solution for nondestructive quality control.

Yes with both the DeskTom and EasyTom CT scanners.  They both support metrology grade Computed Tomography (CT) inspection.  This provides nondestructive, 3D Scanning of Internal and External Geometries.  We use the Volume Graphics VGStudio Max high-end industrial CT software for the demanding of CT applications.

The scanners we use are as accurate as the industry offers – from anybody at any cost. We use Faro and Artec 3D scanners, in addition to Faro CMM type arms, including the Surveyor tables. Depending on what scanner we use:

• CT scanners – 4 to 400µm/voxel resolution
• Artec Portable scanners high accuracy (0.03 – 0.05mm)
• Artec Portable scanners high resolution (up to 0.15mm)
• Our CyberGage 360 – generates highly precise full 360 degrees automated scan with accuracy NIST traceable to approximately 7 microns
• The CyberGage 360 has a system repeatability of ±.005mm.
  

• Faro Arm – Very good for most parts, fast and accurate
• Turntable scanners – high accuracy, high detail, fast scanning. Great for smaller parts.
• Portable handheld – may be favorable for some larger parts – if not a tripod-mounted scanner.
• Long Range – these mount on a tripod, and are intended to scan buildings, plants, and other larger sized projects.
• Industrial CT scanners – incredibly expensive, but they offer two main benefits – the ability to inside an object (think of a void in a solid object), and their accuracy.  At this level, we are often in the ±.001” – ±.002” range, and often used in metrology scanning.

A point cloud is thousands if not millions of data points located in space by X, Y, Z coordinates. Images of this nature are often captured with Faro Focus or Artec scanners that specialize in large-area scanning.  Most likely you obtain building and territory plans in this file format.

‍

A polygon mesh is a set of triangles located in the same manner. These scans are obtained with Artec, Creaform, Enscan and other handheld scanners. Parts and reverse engineering device scans are usually polygon meshes.

It depends on the complexity of the scanned model and material properties. As, for example, it may be much more complicated to properly scan an object with a reflective surface, than a non-reflective surface. It also depends on three main factors:

1. the physical size of your part
2. the required scanning resolution
3. if industrial CT or metallurgy scanning is needed

Simple quick cell phone photos are worth a thousand words to us. To know for sure you can request a quote. It is of course, free – and treated as if an NDA is already in place.

Some averages:

• The typical 3D scan is somewhere around $200-400 per part.
• Tomographic (CT) scanning is $600-900 per part.

Because so much of our business is Aerospace related, our scanning – and the completed CAD file HAS to be within ±.005” anywhere on that part, we never use consumer-grade scanners. The scanners we use start at $25,000 and go up to $700,000 (CT) per scanner.

At any given time, we have in excess of $ 5 million just in scanning hardware we use. In addition, a hidden factor of scanning on any system is the assembly and clean up of any scan. The rule of thumb is a 2-1 ratio. So even with our experienced scanning staff, if we spend one-hour scanning; we will then spend an additional two hours of clean up and assembly before our CAD group gets the Point Cloud file to simulate or reverse engineer.

Yes, we do. CAD/CAM Services employs over 100 engineers and drafters to handle your most challenging engineering projects. When you need an engineer, you need CAD/CAM Services.
