Integrated Aerospace Manufacturing and Assembly: Maintaining High-Precision Tolerances and Part Compatibility

Integrated Aerospace Manufacturing and Assembly: Maintaining High-Precision Tolerances and Part Compatibility

At Snowline, precision defines our process – from the initial engineering support we offer to the final assembly of your end products.

Through our vertically integrated manufacturing model, we bring together design assistance, CNC machining, metal fabrication, finishing, welding and assembly within the same facility. Our coordinated approach gives us the ability to maintain tighter tolerances, reduce variability, and ensure every component fits and functions exactly as specified. Moreover, our end-to-end aerospace manufacturing services give you a single point of contact and accountability as your project moves forward.

The advantage is obvious: rather than working with multiple manufacturers and third-party aerospace assembly companies – which tends to create extra costs, complications, scheduling conflicts, and/or potential bottlenecks – you work directly with Snowline’s experts to resolve any assembly issues that arise, as well as to make future product modifications if needed.

Learn more about the advantages of Snowline’s integrated manufacturing and assembly processes below.

Engineering Better Aerospace Assemblies from the Start

One of the most important aspects of the Snowline process is early-stage engineering collaboration. We work closely with our customers when necessary to optimize part geometry, materials, and manufacturing strategies before any metal hits the shop floor.

Our team uses SolidWorks, AutoCAD, SurfCAM, and Virtual Gibbs to align CAD models with real-world manufacturing constraints to minimize design iterations and any mid-production changes. Whenever beneficial to your products, we employ design for manufacturability (DFM) and design for assembly (DFA) support helps ensure a smoother path to production while enhancing part-to-part compatibility.

Design for Manufacturing (DFM) Combined with Design for Assembly (DFA)

As the name suggests, design for manufacturing and assembly (DFMA) combines DFM with consideration of the overall assembly design. We ensure optimal fit while simplifying the required assembly procedures wherever possible, simultaneously maximizing your end product quality and production efficiency.

For designs that would benefit from DFA refinement, Snowline’s experts aim to:

  • Reduce the number of separate parts if possible, thus reducing the complexity of final assembly as well as associated material handling and inventory logistics.
  • Design for ease of part handling and orientation, ensuring parts are intuitive to pick up, align, insert, and/or fasten in final assembly.
  • Design for error-proofing, removing the potential for incorrect assembly or part orientation.
  • Standardized and/or modular components wherever possible further reduces the cost and complexity of assembly and ongoing inventory control.

Better Tolerance Control and Repeatability for Your Products

Planning out the total manufacturing process in mind, up to and including turnkey assembly, Snowline embeds precision into every stage of your build. Rather than relying solely on final inspections to catch problems, we design and refine our processes to maintain tolerance stack-ups from the start. Closed-loop machining, continuous in-process inspection, and real-time QA feedback allow us to correct issues before they ever reach the assembly stage.

In addition to overall quality and efficiency, our integrated process results in better part compatibility and fitment for multi-component assemblies. Because every separate part comes from the same production line and exacting process control, you can always count on precision and repeatability to be maintained at Snowline Engineering.

Manufacturing Quality Control & Production Solutions

Root Cause Analysis in Aerospace Manufacturing – The Five Whys and Six Sigma DMAIC

Root Cause Analysis in Aerospace Manufacturing – The Five Whys and Six Sigma DMAIC

In the complex world of modern aerospace manufacturing, root cause analysis (RCA) is more crucial than ever. Whether a part fails entirely or simply fails to perform as expected, we have to thoroughly analyze the potential causes from every angle. Only then can we drill down to the true underlying issue, and ultimately improve upon the part design or manufacturing process so that the issue is resolved.

That’s where the “Five Whys” method comes into play, along with the Six Sigma model of “Define, Measure, Analyze, Improve, Control” (DMAIC).

The Five Whys Explained as Related to Aerospace Manufacturing

The Five Whys is a versatile problem-solving method commonly employed by aerospace manufacturers for root cause analysis. It helps us identify the actual underlying issues that lead to subpar quality, functionality, performance, or longevity. Moreover, it gives us a plan of action to correct the issue.

As the name suggests, the method involves asking “why” iteratively – typically framed as a five-step process – drilling down into the true cause-and-effect nature of the issue at hand.

Essentially, we repeatedly question why the issue arose until we arrive at an actionable response. We then take the necessary steps to improve upon the design, materials, or production process and develop a better end product that meets all functional requirements.

Six Sigma DMAIC Explained: Design, Measure, Analyze, Improve, Control

Six Sigma DMAIC is a data-driven methodology which we use in conjunction with the Five Whys approach to optimize the production process and eliminate quality issues, part defects, or variability. The DMAIC process can play a critical role in achieving high-quality production parts with the highest level of repeatability, thus meeting the stringent safety and precision standards of the modern aerospace industry.

  • Define – We start by identifying the problem or opportunity for improvement in manufacturing. This often involves stepping back and looking at the overall production process from a holistic perspective. We can then define the specific issues, resolutions, and plans of action.
  • Measure – We quantify the current process and results to create a baseline. We gather all relevant data for analysis to likewise quantify the progress and improvements that we make.
  • Analyze – We carefully analyze the data, using it to identify specific root causes for the issue at hand or for inefficiencies in the production process. Combined with the prior two steps, this lays out an actionable plan for improvement.
  • Improve – Finally, we implement solutions to address the root causes previously identified. These are carefully laid out plans of action involving much further data measurement and analysis to confirm results.
  • Control – After we implement design and/or process improvements, we ensure the improvements are sustained in future production runs.

Why Root Cause Analysis Is Crucial in Modern Aerospace Manufacturing

In modern aerospace manufacturing, precision and safety are paramount, and quality standards are extremely strict. Both the Five Whys and Six Sigma DMCA are effective tools which help us minimize manufacturing errors and defects, while simultaneously maximizing end product safety, performance, and longevity.

Before manufacturing is fully underway, the Five Whys help us avoid defects by uncovering issues in design, material quality, or manufacturing processes. That simultaneously improves safety, identifying the root causes of potentially hazardous flaws and helping to prevent critical failures.

Likewise, the process ensures compliance with regulatory protocols by addressing gaps that could lead to non-conformance with industry standards. Finally, root cause analysis can actually streamline the overall manufacturing process through revealing inefficiencies and bottlenecks within the production line.

Machine Learning in Manufacturing

How Machine Learning is Applied in Modern Aerospace Manufacturing

Machine learning is an increasingly integral tool within the modern aerospace manufacturing space. When it comes to fabricating high-precision products with complex designs, this expertise provides today’s aerospace manufacturers with a streamlined means of product development, along with more efficient and reliable manufacturing processes to follow.

Below, we take a look at some of the emerging use cases for machine learning in manufacturing. While Snowline Engineering doesn’t always employ such tools for every custom fabrication project, it’s nevertheless interesting to explore what new production possibilities machine learning and AI are bringing into the factory.

Machine Learning and AI in Aerospace Product Design

To an extent, product design has been partially automated for decades – ever since the use of CAD and other digital design tools rose to prominence. Modern machine learning algorithms take automation in aerospace design to the next level.

An increasing number of aerospace product developers are turning to machine learning programs for iterative design. It’s essentially a form of digital prototyping. AI algorithms are able to generate multiple design options based on a set of performance criteria. That allows engineers to more easily explore unconventional designs, potentially developing new product innovations or more efficient ways to make their current products.

From AI to CNC Systems and Robotics

Following product development, these models are used to simulate and optimize the actual manufacturing process.

In simulation programs, the goal is often to spot production line issues or bottlenecks early, streamlining the setup process to follow. In machine monitoring programs, AI algorithms provide real-time feedback and adjustments to ensure that production stays within tolerance levels. For example, machine learning algorithms optimize cutting paths for laser cutting, bending, and punching machines, reducing material waste and processing time

Machine learning is also commonly used to control robotic systems in the welding and assembly of aerospace sheet metal components. Advanced robotic systems can learn from real-world feedback to improve precision and repeatability, essentially learning how to automatically adapt to changes in part geometry.

Automating the Quality Control Process

Machine learning is also increasingly utilized in aerospace quality control and monitoring processes. AI models can detect subtle defects or deviations from production standards using precise sensor data and analytics. This helps in identifying potential issues before they add significant cost or complexity to the production process.

Quality control systems integrated with automated vision systems automatically inspect fabricated metal parts for defects – everything from structural cracks to small scratches or precise dimensional inaccuracies. As with automated manufacturing, vision systems can harness AI to learn from past errors and improve accuracy over time. More advanced systems for structural health monitoring (SHM) and analysis are also increasingly employed to guarantee the structural integrity of parts.

Machine learning is also employed in general production process monitoring/optimization. By analyzing past production data, machine learning algorithms better predict the likelihood of quality issues in parts, allowing operators to adjust parameters before any defects reach full-scale production.

Crucial Considerations for Finding the Optimal Stainless Steel Fabricator:

Focusing on Industry Experience

It’s not enough for a fabrication company to claim they can accomplish “aerospace quality” – you need a manufacturer that has the real-world experience to back it up. Due to the extremely specialized nature of the industry, the majority of contract manufacturers you’ll come across likely won’t have any significant experience in manufacturing aircraft parts.

That doesn’t mean these providers can’t manufacture precision parts within acceptable specifications. However, it does mean that they generally won’t be able to provide the engineering expertise or industry connections that a dedicated aerospace manufacturer like Snowline does. Our company is backed by well over half a century of innovation and experience serving state-of-the-art fabrication projects worldwide.

Meeting the Unique Challenges in Aerospace Welding and Sheet Metal Fabrication

The Unique Challenges of Aerospace Welding and Sheet Metal Fabrication

Today’s aerospace welding and fabrication projects pose some unique challenges to manufacturers. From specialized materials such as exotic metals to highly advanced welding technologies, fabricating the complex products used in modern aviation and spaceflight requires the utmost in manufacturing experience, capability, and precision.

Below, we take a closer look at some of the biggest challenges we face in fabricating precision aerospace products. Backed by well over half a century of delivering superior quality, Snowline continues to rise to these challenges in 2024 and beyond.

Choosing the Optimum Material for Each Custom Aerospace Application

Before welding even begins, we need to ensure an optimum material for the application at hand. A wealth of information in materials science is considered to choose the best-suited material in terms of performance, longevity, ease of manufacturability, and of course cost.

In many applications, standard grades of steel and other commonly fabricated metals simply don’t offer the physical and mechanical properties that aerospace manufacturers are looking for. Careful material choice is paramount in order to produce the lightest, strongest, most efficient aviation parts possible.

A Look at the Common Aerospace Metals

Due to its high strength-to-weight ratio, along with its relatively low cost and wide availability, aluminum remains the most prevalent material in aerospace manufacturing. As virtually everyone with experience in fabrication knows, welding aluminum presents some unique challenges of its own. (More on that below.)

However, many aerospace parts demand even higher strength, a longer fatigue life, enhanced corrosion resistance, or other unique material properties that conventional aluminum simply can’t provide. In these cases, special alloys or exotic metals are used, including titanium, Inconel, and even highly specialized blends of stainless steel. Welding all of these state-of-the-art materials with precision and consistency requires a highly experienced, highly flexible industrial fabricator like Snowline.

Establishing Reliable Aerospace Welding Processes for Challenging Materials

Once we’ve chosen the material, we need to match it with a suitable welding process. While the two most common welding techniques – MIG and stick welding – are still used in some aerospace manufacturing applications, many projects require TIG welding and other more advanced processes. Specialized welding techniques are often needed to work with aluminum and exotic metals, or for merely accommodating the clean precision welds and complex component designs that today’s aerospace products often demand.

TIG Welding for Complex Aerospace Parts

TIG welding is the most common aerospace welding technique due to the process’ precision, repeatability, and material flexibility. Additionally, many other welding methods are used in specific aircraft component applications, whether to achieve unique performance attributes or increased cost effectiveness. These methods include all other electric arc welding processes as mentioned such as MIG and stick welding, as well as other unique methods such as friction stir welding and electron beam welding.

By mastering a number of diverse welding processes, Snowline is able to serve a much wider range of aerospace projects without compromising on any design or performance parameters.

Complex Weldments and Precision Parts Fabricated to the Most Exacting Standards

As we mentioned, one of the major challenges in modern aerospace manufacturing is the high degree product complexity, along with the precision that must be consistently maintained. It’s often not enough to find a fabricator that can produce a one-off part, prototype, or small run of parts. Many projects demand a reliable contract manufacturer that can continuously provide critical parts built to the exact same specifications and standards.

Utilizing state-of-the-art fabrication technology – including advanced CNC systems and automation – Snowline is able to reliably produce ultra-precision parts and welded assemblies for low-volume and high-volume production projects alike.
