When starting the digital manufacturing process with many manufacturers, it can be easy to upload a CAD file into multiple online quoting tools.
Unfortunately, some manufacturers' online quoting tools don’t take into account all of the back-end requirements, or offer all of a manufacturer’s processes. This is where we choose to be upfront so that each step required for the part or project is reflected in the initial quote.
When using online digital tools, quoting software can greatly accelerate development and production cycles.
However, to get the most out of these tools, make sure you are working with software (and a manufacturer) that includes the following:
A major challenge in the aerospace and defense industry is on-time delivery and quality. Industry sources say around 80% of orders generally show up on time. Yet, when those orders do show up on time, about 25% of parts do not meet the required quality. A common complaint from aerospace companies is when vendors promise a lead time with a cheaper price but could not deliver within the timeline quoted. Delays have led to missed deadlines and greater costs to fix than if they would have just started with the higher-priced vendor.
Our online, interactive quoting system turns your CAD model into a quote with immediate design analysis and feedback. Your design can be reworked to determine the ideal balance of processes, materials, time, and cost. This greatly increases efficiency as it isn’t necessary to talk with someone every time a part is needed. But when you need a knowledgeable person on your side, we have a team of applications engineers ready to back up our automated tools. All contacts, customer or not, get free access to our responsive team that understands how to design for our processes, reduce cost, and answer a myriad of other technical questions.
You may want to reduce overall components in a part or product design for several reasons.
First, lightweighting is crucial in aerospace. Companies know just how many ounces of fuel it takes to fly a gram of weight in flight, for example, so slight reductions drive major gains. The choice of materials, and sometimes the method of manufacturing, also factor into this lightweighting equation. But trimming part count helps, too.
Second, cutting costs is important. Plastics and metals can be expensive, and so can assembly time. Accordingly, if designs can lessen the number of components or parts, this can reduce materials and assembly time.
With these lightweighting and cost considerations in mind, which materials work best for aerospace components? Titanium is often a go-to choice, available through machining and 3D printing services. This lightweight and strong material offers excellent corrosion and temperature resistance. Aluminum, and its high strength-to-weight ratio makes it a good candidate for housing and brackets that must support high loading. Aluminum also is available for both machined and 3D-printed parts. Inconel, a 3D-printed metal, is a nickel chromium superalloy ideal for rocket engine components and other applications that require high-temperature resistance. Stainless steel also is a frequent materials choice. For example, SS 17-4 PH is used in the aerospace industry due to its high strength, good corrosion resistance, and good mechanical properties at temperatures up to 600 degrees F. Like titanium, it can be machined or 3D printed. Liquid silicone rubber is also widely used in the industry. This elastic fluorosilicone material is specifically geared toward fuel and oil resistance while optical silicone rubber is a good PC/PMMA alternative. Common applications in aerospace include soft-touch surfaces, gaskets, seals, and O-rings.
Finally, beyond lightweighting and cost cutting issues, the aerospace industry faces unique benefits and challenges with high risks and rewards. Companies are concerned with development cycles, prototyping, hot-fire testing, and production. So, while component reduction can help reduce part weight and assembly time, the real savings are in the reduction of the headaches and overhead associated with the supply chain and paper trail for each part. In aerospace, each component that goes into the final product has a tremendous amount of validation behind it such as material traceability, shock and vibe tests, rigorous inspections, and much more. In such a regulated industry, reducing parts can provide great value by reducing inventory, having fewer documents to track, and streamlining your supply chain.
If you have an internal machine shop but have to deal with a lot of different types of manufacturing in a small space, you might have taken projects to outside vendors for development work. It is important to find the right vendor with the capacity to meet your high demands for quality and speed. You may know but it bears repeating that there are no universal processes or materials. You need all the tools in your arsenal to find the best solutions to stay on the cutting edge. Therefore, work with companies that are able to offer a range of manufacturing processes and materials. We offer CNC machining, sheet metal fabrication, injection molding, and six different industrial-grade 3D printing (additive manufacturing) methods. Additionally, you can choose from hundreds of commercial-grade plastics, metals, and elastomers that are suitable for both prototyping and production. See our Materials Comparison Guide for a complete list.
We use multiple additive processes: stereolithography, direct metal laser sintering (DMLS), selective laser sintering, Multi Jet Fusion, Carbon DLS, and PolyJet. DMLS has proven to be a desirable process in the aerospace industry because it offers:
DMLS does have a limited build space. However, we also offer large-format metal parts. We can build production-grade metal parts as large as 31.5 in. x 15.7 in. x 19.7 in. (800mm x 398mm x 500mm). We are initially focusing on Inconel 718 as a material to use to better serve the demand for larger complex parts in the aerospace industry. This large-format metal 3D printing, from our GE Additive Concept Laser X-Line machine, also is an example of how our company is technology agnostic, using machines, equipment, and processes sourced from a variety of companies.
Beyond the manufacturing methods referenced (subtractive and additive), we also offer a number of secondary or finishing options, if your design calls for these applications:
If you need several vendors for different processes or secondary processes, remember the benefits mentioned earlier about using one supplier with multiple processes. We offer many processes and materials while operating as a local vendor to reduce time and costs.
In addition, as we recently noted in our trend report on aerospace manufacturing, often the best solutions for aerospace and defense will involve a hybrid approach using multiple technologies in concert. Just as a traditional toolbox contains both hammer and pliers, so too do today’s advanced manufacturing operations house both additive and subtractive manufacturing systems and know-how.
Finally, aerospace product designers and developers need to carefully navigate government and safety policy and compliance issues. Working in such a highly regulated industry, it is important to find vendors familiar with aerospace requirements. Traceability, documentation, testing, and certified parts that are USA/ITAR compliant in an ISO environment can decrease much of the work needed to be done, tested, or verified in house.
Governing bodies are continuously working on standards for additive manufacturing, so knowing exactly what is needed may be difficult to find for non-traditional processes. However, standards or certifications for finished parts apply no matter how it was manufactured. You will want to make sure vendors have certified materials, powder analysis, material traceability, and more depending on your needs.
We have already invested heavily in digital manufacturing methods to provide you with automated tools, documentation, testing, and traceability, all supported by our applications engineers, delivering you a streamlined and efficient digital thread. We offer the following quality documentations and report options in an ISO , AS certified, USA/ITAR compliant environment:

With such overwhelming demand, aerospace CNC machining has emerged as one of the most extensively employed manufacturing techniques in aerospace engineering.
Whether you are unfamiliar with the implementation of CNC machining in aerospace engineering, here are some crucial points that will guide you on how this machining process is doing wonders in the domain of aerospace:
The most commonly used metals in manufacturing different aircraft are aluminum and titanium due to their immense strength. These metals dominate the industry because they are relatively lightweight than steel or any other metal. Using light metals boosts fuel economy and the overall performance of aircraft.
However, the manual machining of these metals is tedious and time-consuming. This is where CNC machinery benefits the aerospace industry by offering compatibility with an extensive variety of materials and providing seamless fabrication of these metals.
R&D is a vital sector in any industry, and CNC machining lies at the forefront of this phase. Since CNC machines take instructions from 3D CAD models to manufacture parts, aerospace engineers can swiftly develop new prototypes, test and edit them in real-time.
CNC rapid prototyping is economical for aerospace companies as it minimises expenses by disposing of the need to invest in tooling. Besides, it facilitates aerospace companies to comply with regulatory requirements, including AS and ISO : standards.
The complexity of aerospace component designing is consistently on the rise. For instance, NASA’s Orion bulkhead, a component that ensures crew safety has a dome structure near the heat shield and has pockets normal to its surface.
Yet another example is the enormous sizes of the aircraft landing gears and fuselage sections that feature tiny details and demand extremely tight tolerances.
Catering to these demands requires the aid of 5-axis CNC milling machines to manufacture even the most complex parts. These machines can deliver reaches and angles that might not be feasible to attain using 3- or 4-axis machines.
The latest CNC machines in the aerospace industry feature Artificial Intelligence (AI) augmented with Machine Learning software.
This combination has allowed aerospace companies to determine accurate production metrics and seamlessly attain aerospace part production targets. It has also helped improve the quality and longevity of machined aerospace components.
Aerospace industries depend on third-party manufacturers to obtain different components. These components must have tight tolerances and interlink precisely with parts from other machine shops.
Precision CNC machining enables aerospace companies to manufacture components meticulously as specified and deliver tolerances as small as 4μm. In an industry where part failure while being in a flight is not an option, CNC machining renders unparalleled precision.
Accuracy is a vital component in constructing aircraft, be it fighter jets, cargo planes, or commercial airlines. Every phase of an aircraft’s construction demands unprecedented accuracy, whether it is the innermost layer or the outer shell.
For exterior operation, the engine is the most crucial component in an aircraft, and thus, it must process and burn fuel with no leakage or component malfunctions. CNC machining helps manufacture the most intricate parts critical to the streamlined operation of the engine.
For interior components, CNC machining plays a pivotal role in designing the cockpit. Some of the tiniest interlinked parts make up the navigational system that provides directions to the pilots in real-time.
CNC machining helps manufacture these tiny CNC machining aerospace parts, which might require fine-tuning and tweaking from time to time. CNC machined parts boast extreme precision and significant endurance to rule out any odds of failure.
Space travel agencies such as NASA and SpaceX scrupulously design and construct the most technologically advanced rockets and spacecraft for various deep-space missions.
This is where aircraft CNC machining enters the picture. The CNC machining process is pivotal to manufacturing infinitesimal parts that tether the rocket’s body design.
Components must operate without fail and prioritise the safety of the spacecraft and its crew members. Since space travel demands no scope of errors, CNC machining has been expanding rapidly in this sector.
It is imperative that you pick an appropriate CNC lathe for your machining shop to prevent inaccuracies and deliver components that are best-in-the-business.
The aerospace industry demands state-of-the-art requirements and full compliance with industry standards. The delicacy of the utilisation of aircraft and spacecraft makes it pivotal to use high-grade components.
Besides offering extreme precision and tolerance, aerospace CNC machining is significantly more time-efficient for engineers to make edits and run tests. It is advisable to conduct thorough research before finalising a CNC machine to ensure that you get the most value for your buck.
