DarkAero, a pioneering aerospace company based in Madison, WI, is on a mission to revolutionize personal aviation. Established by the visionary trio of brothers-Keegan, River and Ryley Karl-DarkAero combines cutting-edge engineering and sophisticated manufacturing practices to turn their collective vision into reality. Central to its manufacturing process is the Tormach 1500MX CNC Mill, which has become an indispensable tool in the company's intricate production and prototyping efforts.
DarkAero, which aims to make aviation more accessible and efficient by providing cutting-edge aircraft kits that enthusiasts and builders can assemble themselves, is developing an experimental aircraft designed for speed, long-range travel and efficiency. The Karl brothers' engineering backgrounds in mechanical, aerospace and electrical have uniquely positioned them to innovate in this space.
DarkAero offers aircraft in kit form, with an emphasis on components that are lightweight and ready for assembly, without overly complex requirements. Leveraging multiple Tormach machines, DarkAero not only prototypes, but also manufactures these critical parts. This approach emphasizes design for manufacturability, ensuring components are manageable to produce and assemble.
"What we are doing at DarkAero is developing a high-performance aircraft kit that combines lightweight composite materials with precision-engineered metal components," said Keegan Karl, co-founder and Vice President of DarkAero. "We are now transitioning from the prototyping stage into flight testing and production activities. Throughout the whole process, we have been using Tormach equipment, including the 1100 PCNC and now our newest model, the 1500MX."
The potential for complexity in manufacturing and assembly poses a significant challenge for any aerospace company. To mitigate these risks, DarkAero capitalizes on its capacity to prototype inexpensively in-house, utilizing Tormach machines to craft authentic, production-ready aerospace parts. This strategy helps ensure a smooth, efficient manufacturing process.
The Tormach 1500MX has been a game-changer for DarkAero as the new machine's capabilities have improved workflow, especially in terms of production readiness and precision.
"We were really excited to have the very first 1500MX unit in our shop to test out and see what it is capable of," Karl said. "We learned quickly that this machine is extremely capable. The spindle can go up to 10,000 RPM. It also has rapid movements of 1,200 IPM for X and Y, and 600 IPM for Z, which means it has a greater rate of material removal than the previous model."
One of the standout features of the new Tormach 1500MX is its large machining envelope, which allows for the creation of bigger parts. This is crucial for DarkAero as it transitions from prototyping to production. The machine also includes through-spindle coolant and a washdown feature, reducing the manual cleanup and set-up time.
"On the 1500MX, the coolant comes out of the spindle head and can go through the tools, which helps in reducing tool wear, improving cutting efficiency and maintaining tighter tolerances on the machined parts," Karl added. "It also has a washdown feature that takes all the chips generated during the machining process and funnels them into a collection unit at the back. This is a huge upgrade from what we had before."
When it comes to production, the new Tormach 1500MX has allowed DarkAero to streamline its manufacturing process, making it more efficient and less error prone. The machine's automatic tool changer and built-in camera for monitoring crashes are just a few of the features that enhance its usability and reliability.
"The automatic tool changer is a significant time-saver," Karl explained. "You can upload your program, hit go and then walk away to get other things done without worrying about chip evacuation or changing out tools. The built-in camera records any emergency stop events, helping us diagnose problems quickly."
The ability to prototype and produce parts in-house has been a crucial advantage for DarkAero. It allows the company to rapidly iterate on designs and make improvements without the delays associated with outsourcing. This flexibility is especially important in the dynamic field of aircraft design.
"There are benefits to throwing it over the wall and outsourcing it sometimes, but if you have the capability to do it all under one roof, things can happen much more quickly," Karl said. "We can make changes on the fly, update the CAM and run with it. This tight feedback loop has been invaluable for us."
DarkAero's collaboration with Tormach and commitment to an in-house operation has enabled it to push the boundaries of what is possible in personal aviation. The Tormach 1500MX CNC Mill has provided the precision, efficiency and flexibility needed to bring DarkAero's innovative aircraft to life.
"The Tormach 1500MX has really shown a high level of automation for us," Karl said. "A lot of time previously spent on set-up and cleanup is now heavily offloaded onto the machine. We are quite excited and look forward to creating more parts and sharing more content about this incredible machine."
