Frequently Asked Questions (FAQ)
1. What are digital twins in manufacturing, in simple terms?
A digital twin in manufacturing is a virtual, dynamic model of a physical asset (like a machine) or a process (like an assembly line). It is continuously updated with real-world data from sensors, allowing it to mirror the exact state of its physical counterpart. This allows companies to test, monitor, and predict behaviour in a digital space without any real-world risk.
2. What is the difference between a digital twin and a simulation?
This is a critical distinction. A simulation typically studies a process or system under hypothetical conditions to see what could happen. A digital twin is a simulation that is continuously connected to a real-world physical object and is updated in real-time with its data. In short, a simulation predicts what might happen, while a digital twin models what is happening right now and uses that to predict what will happen next.
3. Can small and medium-sized businesses (SMBs) use digital twin technology?
Yes, absolutely. While early adoption was led by large corporations, the rise of cloud computing and more affordable IoT sensors has made digital twin solutions increasingly accessible. SMBs can start small, for example, by creating a digital twin for a single critical machine to prevent downtime, rather than an entire factory. The key is to start with a high-value problem and scale from there.
4. What is the typical ROI for a digital twin project?
The Return on Investment (ROI) can be massive and is often realised in multiple areas. Companies report significant ROI from:
- Reduced Downtime: Preventing a single major production stoppage can often pay for the entire project.
- Lower Prototyping Costs: Drastically reducing the need for expensive physical prototypes saves millions in R&D.
- Improved Quality: Reducing scrap and rework by 15-20% is a commonly cited benefit.
- Increased Efficiency: Optimising a process to improve throughput by even 5-10% generates continuous value. While initial costs exist, the long-term financial benefits are typically very strong.
5. What kind of data does a digital twin need to work?
A digital twin thrives on data. The specific types depend on the application, but commonly include:
- Operational Data: Temperature, pressure, vibration, speed, energy consumption from IoT sensors.
- Positional Data: Location and movement from GPS or RFID trackers for logistics.
- Manufacturing Data: Production rates, error codes, and quality metrics from factory systems (MES).
- Environmental Data: External factors like humidity or ambient temperature that might affect a process.
6. How will AI and the Metaverse shape the future of digital twins?
The convergence is already happening. Artificial Intelligence (AI) is the “brain” that analyses the data from the twin to find patterns and make predictions. The Metaverse provides an immersive, 3D space to interact with digital twins. In the future, teams of engineers from around the world will meet inside a virtual factory (the industrial metaverse), interact with its digital twin, and collaboratively solve problems as if they were physically there.
7. How is this technology used in VR training?
By connecting a digital twin to a VR headset, a company can create a hyper-realistic virtual training environment. This is now considered by many to be the best simulation-based training in the VR industry because it allows employees to practice on dangerous equipment in a completely safe yet perfectly responsive setting that behaves exactly like its real-world counterpart.
