In another recent application, our team delivered a system that automates industrial documentationdigitization, effectivel… It is observed that up to 20% of AFP production time is associated with visual inspection [2]. Maintenance is a necessary evil that’s worth the time because an equipment breakdown on the assembly line can cost far more. For the greater portion of engineering problems, closed form or numerically solved analytic solutions find use and success. Machine learning (ML) and Artificial Intelligence (AI) are currently being explored for a number of advanced manufacturing applications, and their applicability has begun to extend into the composites manufacturing realm. Machine Learning is hyped as the “next big thing” and is being put into practice by most of the businesses. This goal has forced organizations to evolve their development processes. In this document, a comprehensive overview of machine learning applications in composites manufacturing will be presented with discussions on a novel inspection software developed for the Automated Fiber Placement (AFP) process at the University of South Carolina utilizing an ML vision system. The capability to automatically, accurately, and reliably identify process signatures and even inform the optimization of manufacturing parameters creates new opportunities for improvements in quality, scheduling, and seamless transparency across the whole value chain. Traditionally, laborious simulations are required to account for the many degrees of freedom that these models present. The data in Figure 5 represents a valid impact test. The large-scale adoption of composite materials in industry has allowed for a greater freedom in design and function of structures and their respective components. Finally the topology known as ResNet [26], [27] has demonstrated state-of-the-art accuracy in image classification. Herein, an optimisation framework of a full-scale wing-box structure with VAT-fibre composites is presented, aiming at minimised mass and optimised local buckling performance under realistic aeroelastic loading conditions. The research objective of this work is to enhance the perception of, sensing in, and control of smart manufacturing systems (SMS) by leveraging active sensor systems within smart products during the manufacturing phase. Using very accurate and very fast commercially available sensors combined with specialty software, layup inspection can now be performed automatically. ... Lead time prediction using machine learning algorithms: A case study by a Using a mining case study, we will show how to get started using machine learning tools to detect patterns and build predictive models from your datasets. The additional accuracy afforded through the AFP process has led to greater functionality of design, and thus sped adoption of advanced composite materials in a number of fields, primarily aerospace, but also the automotive, energy, maritime, biomedical and sports sectors. However, in order for this discussion to proceed, we must broach the area of the convolutional neural network (CNN) and it’s application. Supervised Machine Learning. This course is a case study from a machine learning competition on DrivenData. Humans are typically far better at identifying colors, cracks, shine, and other issues that could indicate a quality control issue. This survey reviews published reports of deploying machine learning solutions in a variety of use cases, industries … This isn’t just the case with the products rolling off the assembly line but with the machinery that creates them in the first place. While its DNA was squarely rooted in the assembly line, they took the notion of lean manufacturing a few steps further by identifying the seven most common wastes that arise in the manufacturing process and using that as a legend to streamline their process. Even in those cases where visual inspection is intended to be exacting, the precise characterization of a given defect remains elusive. This is one of the basic machine learning use case in manufacturing. The objective of the Mercedes-Benz Greener Manufacturing competition is to develop a machine learning model that can accurately predict the time a car will spend on the test bench based on the… It should be noted that while the score for the FOD and wrinkle classes are low, they respectively constituted 0.005% and 0.5% of pixel space among the images in the training set. They rely heavily on machine learning to identify the most optimal route to get the passenger from point A to B. To improve production capacity and avoid downtime, a global biotechnology manufacturing company implemented Seebo Predictive Analytics. Success in manufacturing is evolutionary in the purest sense, predicated on the notion that the company that creates the most efficient processes for development will prosper while those that fall behind will die. However, there is still a lack of knowledge in the study of impact response of and damage propagation in composite plates at low-velocity impact loading in the presence of the manufacturing defects. AlSi10Mg particles were cold sprayed on the treated surface, and the low-velocity impact behaviour of the metallised hybrid structures was analysed in details. While the accuracy scores, We have demonstrated a novel inspection methodology for the detection of manufacturing defects in the AFP process. The German conglomerate Siemens has been using neural networks to monitor its steel plants and improve... GE. It has also achieved a prominent role in areas of computer science such as information retrieval, database consistency, and spam detection to be a part of businesses. The power of machine learning is utilized behind the scenes: However, no matter how appealing the idea of ML may be, it can’t realistically solve every business problem, or turn struggles into successes. “I was skeptical that the ML engine would be able to detect the failure because there was only data available in one-hour intervals and only whole-number increments on temperatures,” says Arnold. ● If you perform it too late, you could potentially see a full breakdown of the assembly line process. Machine Learning Case Study. We determined this challenge could be solved using one of the many machine learning frameworks.

It became such an effective model that years later Toyota would teach the principles to GM in an exchange where General Motors would help them acclimate to the American market. Find case studies and examples from manufacturing industry leaders. That was the case with Toyota who, in the 1970s, found themselves falling behind General Motors in terms of efficiency. However, the field is very broad and even confusing which presents a challenge and a barrier hindering wide application. The precise characterization of defects has a logical place in the evaluation of defect effects on structural performance. Fig. The assembly line process and the Toyota Manufacturing Technique are all about improving efficiency in the factor or the plant, but that’s not the only part of the pipeline where efficiency can be beneficial. Minimizing the presence of defects can have a significant impact on minimizing the need for maintenance further down the line (or to prevent putting customers at risk), but even the best-made products are going to break down eventually. Some tasks are inherently more complicated than others. This research was made possible with the support of Nickolas Zuppas and Tyler Beatty. This provides productivity improvements, digital records of the as-made part, improved accuracy and part cost reduction. What are some examples of machine learning and how it works in action? Machine learning can determine the ideal time to maintain equipment, creating a safer and more efficient environment. Fig. It is not a far step to incorporate the data from the inspection process outlined into a finite element model and determine the exact effect said defects will have on the overall structure. A mass reduction of 12.5% and 13.2% is obtained by using the constant-thickness VAT and variable-thickness CTS designs, respectively, compared to a baseline quasi-isotropic straight-fibre design. It involves the diverse use of machine learning. CNNs differ such that rather than a single computing node as reference in Eq. In case of semiconductor manufacturing, sophisticated LT prediction methods are needed, due to complex operations, mass pro-duction, multiple routings and demands to high process resource efficiency.

By creating a tight nucleus consisting of data engineers, domain experts, and plant managers, this study demonstrated the dramatic effects that machine learning could have manufacturing safer products with fewer defects and less risk to the consumer. One recent use case is a study on a large motor failure. Machine Learning-Based Demand Forecasting in Supply Chains. eg. AFP is enabled by the rapid movement and replicability provided by robotic placement of collections of composite material tows, denoted as courses. This update process can be accomplished in a number of ways including genetic algorithm [10], [11], [12], [13], [14], [15] and other semi-heuristic techniques. Key AFP defect types are identified in Table 1. The general motivation of this research is to increase the fidelity of information available to third party groups and tools. The process of storing and then delivering products creates its own inefficiencies that can have every bit as much of an effect on the bottom line as problems on the assembly line can. The substitute model has the same geometric size and is stacked in the same sequence as that of the delaminated portion. In the past decade, machine learning has given us self-driving cars, practical speech recognition, effective web search, and a vastly improved understanding of the human genome. These include data analytics applications and particularly finite element tools designed to find the effect of defects on the global response of a structure. Technical expertise was provided by Kris Czaja and Ingersoll Machine Tools in the operation of the ACSIS inspection system. It could reasonably be seen as the first step in the automation of the labor process, and it’s still in use today. Even under the best computing, What follows is our solution to the AFP inspection problem. Machine learning is not a magic bullet, but it does have the potential to serve as a powerful extender of human cognition. The results were compared with two FE models. Let's take under consideration several data science use cases in manufacturing that have already become common and brought benefits to the manufacturers. Examples of machine learning algorithms and their respective tasks can be found in Table 2. To ensure their high reliability, numerous non-destructive testing (NDT) techniques have been used to detect defects during production and maintenance. Thanks to cognitive technology like natural language processing, machine visi… This new approach pulls from recent developments in machine learning and computer vision to go beyond identification of defects and detection of their class into full quantitative characterization. Machines have long been used to identify risks that can’t be detected by eye, like those predicated on weight or shape. According to such observations, an equivalent model which is perfect, delamination free is proposed to replace the delaminated portion of the laminate. Machine learning is the talk of the technology sector, but it’s such a broad and poorly understood concept in the popular consciousness that it can often be interpreted as something akin to magic. The development of an Automated Ply Inspection (API) procedure for NASA is described. The complexity of many of the manufacturing processes in the production of composite structures dictates that attempts at modeling or optimization often are limited in their scope and application. To tackle this problem, the authors have developed a system for AFP inspection derived from an ML computer vision system that allows for precise defect characterization in addition to class identification. AlexNet [21] demonstrated the ability for CNNs to be extremely effective in object recognition challenges. Unfortunately, human inspectors tend to be slow. Several deep CNN architectures have been popularized. To adjust the network to the desired output, termed training, and error function E is defined such that a distance metric between the desired output and the given network output is produced. There are several parallels between animal and machine learning. Case Study: Providing Smart Hygiene Control in Food and Pharmaceutical Processing Plants. Smart Factories, also known as Smart Factories 4.0, have major cuts in unexpected downtime and better design of products as well as improved efficiency and transition times, overall product quality, and worker safety. Experimental results show that the model can reach 96% classification accuracy (F1_measure) with satisfactory detection results. These nodes perform simple arithmetic computations and propagate the results forward to other nodes. Machine Learning can be split into two main techniques – Supervised and Unsupervised machine learning. Smart manufacturing utilizes rich process data, usually collected by the SMS (e.g., machine tools), to enable accurate tracking and monitoring of individual products throughout the process chain. Infrared thermography is a popular technology for predictive maintenance for obvious reasons. Watchmaker Uniform Wares partnered with Betatype to explore the advantages of additive manufacturing (AM) technology, pushing the boundaries of design in an industry traditionally centred around heritage. Their outputs are scaled by a series of weights that act as tuneable parameters to adjust network output. Machine learning is the science of getting computers to act without being explicitly programmed. From the exact analysis in which the nonlinear contact effect between the two portions above and beneath the delamination is included, it is found that (1) the two portions above and below the delamination undergoes exactly identical global deflection; (1) the composite laminate is subjected to Mode II delamination propagation due to in-plane slipping.
