Digital Twin Tech in Manufacturing: Taking Action with Laser Precision

Decision-making with a high degree of certainty has always been the table stakes for manufacturing companies. No wonder digital twin tech in manufacturing has won such acclaim in the industry. By offering a comprehensive look at a digital footprint of products, digital twin manufacturing software enables industrials to keep a close eye on possible risks and adapt dynamically to evolving needs.  

But we’ve seen it already with AI applications and the likes. So what makes digital twin technology the superstar of manufacturing?

What is a digital twin in manufacturing? Detailed breakdown

A digital twin is a near-real-time virtual duplicate of a physical product or process, used to analyze the performance of the physical assets. Manufacturing digital twins can visualize the entire production, including every step of the product life cycle. This allows stakeholders to simulate, predict, and optimize the product and production system.

By relying on IoT sensors, data analytics, and machine learning capabilities, a digital twin can provide a detailed profile of the historical and current behavior of a physical object, minimizing the need for real-life prototypes. Unlike physical simulations, digital replicas have a larger data pool and are not limited in the number of visualized processes.  

How digital twins in manufacturing work

A digital twin of manufacturing is a multi-layer architecture with a combination of components that communicate with each other to execute a specific function. A core differentiator of the digital twin manufacturing framework is its two-way flow of information that returns the insights created by the object sensors to the original source object.

Although the components, relationships, and interfaces vary by the use case, factory digital twins usually include the following building blocks:

Hardware layer

The Internet of Things is the core technology that lies at the heart of digital twin deployment. A whole lot of sensors, actuators, and network devices capture real-world data and send it further for processing and analysis. The choice of the hardware is specific to each deployment.

Middleware layer

This layer comprises all data management infrastructures and solutions that collate and process data from different sources. At this layer, data is also governed, modeled, and visualized to acquire the operational and behavioral awareness needed to simulate, predict, and inform decisions later in the process.

Software layer

The digital twin then uses artificial intelligence to simulate and demonstrate the effects that the changes in design, process, time, or condition would have. Again, manufacturers don’t need to subject real-world objects to those changes, they just simulate them. Likewise, all changes made in the real world are reflected in the real world. The final insights are delivered to the end user via dashboards and applications.

The triple value digital twins bring to your factory

Until recently, a digital twin for manufacturing has been an elusive concept to global enterprises due to the limitations in technology and hefty computing and storage costs. However, the democratization of technology has made an industrial digital twin a sleeper hit. By 2027, the digital twin market is projected to surpass $73 billion. Let’s see why global manufacturers are rushing to invest in the concept.

Reduced time to market

In an era where time to market is a critical factor for success, even a tiny mistake made early in the product development process matters. It means you have to get everything right — even the prototype of a new machine — from the get-go. Digital replicas provide a risk-free product development environment, allowing design and development teams to try on different options with no associated cost.

According to McKinsey, the digital twins can yield a 50% faster time to market combined with a 10% revenue uplift. Digital twins in smart manufacturing also accelerate commissioning, facilitate testing via integrated physics engines, and streamline collaboration between different teams involved in product development. 

Simulation-based development approach has already gained traction in the automotive and aviation industries. For example, digital twins in the automotive industry allow manufacturers to model mechanical systems on the computer and test them in a simulation environment. 

Improved quality control 

A tighter grip on the manufacturing process is among other benefits of digital twins in manufacturing. The technology shows the real-time factory heartbeat – at the process, system, asset, and component layer. That’s why manufacturers can easily spot the improvements to be made, track product performance throughout their lifetime, and monitor product lines and the factory floor. 

Digital models can also be used to simulate the performance of products in extreme conditions, which allows engineers to detect flaws and improve product quality.

Preventive and predictive maintenance

Among other things, digital twins are used to bring out actionable insights related to product behavior and production processes. This way, engineers can see the state of any part of the manufacturing system at any time, meaning that every anomaly will be put on sharp display.

Digital twin data allows manufacturers to minimize unplanned downtime, optimize maintenance schedules, enhance asset performance, and extend the lifespan of their equipment, reducing the cost of operating.

Types of digital twin applications in manufacturing

The digital twin technology in manufacturing comes in different forms and shapes, based on the level of product analysis. Each type of virtual environment is applied to support different applications, while one factory can have different types of digital twins within a system or process. 

Component twins

A component twin is a virtual replica of an individual part of a system or product, such as a motor or a valve. They are considered to be a basic form of digital twins, yet are indispensable in providing detailed information about a component’s historical and real-time behavior.

Asset twins

Asset twins are exact replicas of physical products on your factory floor. These are usually made up of multiple component twins and offer insight into their interaction. Asset twins help identify potential improvements in plant processes and optimize each part to increase efficiency, reduce mean time between failures, and optimize energy or water consumption.

Systems twins

System twins are virtual representations of the interaction between assets. In manufacturing, these types of solutions are used to facilitate collaboration between assets and find new combinations to maximize efficiency. Put simply, system twins allow you to map the ecosystem of assets you have and the relations between them.

Process twins

High-level process twins are used to model the entire factory, including all the associated manufacturing operations. Process twins allow plant managers to drill down into product data, assess the time it takes to build a product, and monitor key business metrics.

Technologies that underpin digital twins

Building twins is far from simple, but once created, they offer near-limitless potential. The powerful quartet of four advanced technologies that comprise digital twins makes sure you can capture the full value hidden in the application.

Internet of things

In the manufacturing industry, a digital twin platform is often based on a conceptual model that leverages a combination of BIM, CAD, or GIS data and IoT data. Therefore, the operational intelligence of the virtual model stems from the real-time collection of sensor data. The bidirectional communication between digital twins and physical IoT devices is what allows companies to instantly monitor the behavior and condition of physical counterparts.

Extended reality 

Bolstered by extended reality, digital twins promote manufacturing excellence through virtual factory replication. Put simply, the synergy of the two allows users to interact with machines through real and virtual combined environments and remotely control them. XR components also help manufacturers experiment with parameters and situations to test the machine performance.

Cloud computing

Cloud computing provides an easily scalable infrastructure for implementing a digital twin factory. Also, cloud-based digital twins have the computational resources and storage capacity that match a factory’s data needs, while also reducing tooling and setup costs.

Machine learning

Instead of grinding away at industrial data, manufacturing operators make sense of it with ML algorithms. AI-based models process the piles of sensor data, identity patterns, and provide ready-to-use insights about machine performance, maintenance, emissions levels, and other core metrics.

Real-world examples of digital twin use cases in manufacturing

Today, an increasing number of high-flying companies are throwing their hats in the digital twin ring, driven by the need to win the innovation arms race. Let’s have a look at some digital twin manufacturing examples and what benefits industry leaders get from the technology.

Production optimization

Applying a holistic approach to digital twin adoption is what maximizes the value you get from it. In this case, digital replicas can reveal areas of improvement related to the speed of cycle times, efficiency, and machinery utilization. 

That’s what Bosch does. The company accumulates all production sensor data and compares it with a digital twin of a high-efficiency production line to flag deviations and analyze trends. This helped Bosch improve its electronic stability program and automatic braking systems by 25 percent.

After-sales support

The production process doesn’t end with delivering the goods to end users. Manufacturers have to constantly analyze the deliverables to enhance the product quality. 

For example, Tesla creates a digital twin for every vehicle it sells and then gathers real-time data from a vast network of vehicle sensors. By analyzing the data from an individual vehicle, Tesla uploads updates to improve vehicle performance, predict failures, and provide a better user experience for the vehicle owner.

Analysis of assembly-floor behavior 

The modern factory floor is often too dense for stakeholders to optimize workflows on a hunch. However, by having real-time production data for every asset, manufacturers can have a 360-degree view to analyze machine performance according to KPIs, schedule workforce, and ensure proper routing of materials.

Case in point, General Motors uses a process digital twin to mimic plant floor behavior. This digital twin implementation example facilitates advanced technology to boost production, improve process efficiency, and ensure the sustainability of operations.
