One of the key requirements in aircraft manufacturing is achieving precision tolerances, a concern that carries over to additive manufacturing, Researchers at Purdue University and the University of Southern California have developed automated machine learning technology to improve additive manufacturing.
The technology addresses a current significant challenge within additive manufacturing: individual parts that are produced need to have a high degree of precision and reproducibility. The technology allows a user to run the software component locally within their current network, exposing an API, or programming interface. The software uses machine learning to analyze the product data and create plans to manufacture the needed pieces with greater accuracy.
“We’re really taking a giant leap and working on the future of manufacturing,” says Arman Sabbaghi, an assistant professor of statistics in Purdue’s College of Science, who led the research team at Purdue with support from the National Science Foundation. “We have developed automated machine learning technology to help improve additive manufacturing. This kind of innovation is heading on the path to essentially allowing anyone to be a manufacturer.”
Sabbaghi adds. “This has applications for many industries, such as aerospace, where exact geometric dimensions are crucial to ensure reliability and safety. This has been the first time where I’ve been able to see my statistical work really make a difference and it’s the most incredible feeling in the world.”
The researchers have developed a new model-building algorithm and computer application for geometric accuracy control in additive manufacturing systems. This will further enable users to benefit from additive manufacturing, whose competitive advantages include shape complexity, waste reduction and potentially less expensive manufacturing, compared to traditional subtractive manufacturing.
“We use machine learning technology to quickly correct computer-aided design models and produce parts with improved geometric accuracy,” Sabbaghi says. The improved accuracy ensures that the produced parts are within the needed tolerances and that every part produced is consistent and will perform that same way, whether it was created on a different machine or 12 months later.
