Definition of AI

Artificial Intelligence is the ability of a machine to display human-like capabilities such as reasoning, learning, planning and creativity. AI enables technical systems to perceive their environment, deal with what they perceive, solve problems and act to achieve a specific goal. The computer receives data – already prepared or gathered through its own sensors such as a camera – processes it and responds. AI systems are capable of adapting their behaviour to a certain degree by analysing the effects of previous actions and working autonomously.”

Implementing AI in Industrial Settings

Implementing AI Solutions with LCM

LCM assists you in deploying AI for your specific applications, for instance in condition monitoring. Both LCM and your company usually possess deep understanding of the system named “domain knowledge”.

We start with employing customized sensor technology to collect precise system data. Simultaneously, we can create a computer model for system simulation that generates extra data, including possible undesirable states. The domain knowledge is integral to both data collection and model simulation.

Next, the gathered data is analyzed using AI algorithms to assess the current state of components or machinery. Based on this analysis, we activate suitable actuators or actions to maintain optimal system performance.

Important Terms

Machine Learning

Machine learning enables understanding a system through data analysis. With adequate data from various operating states at hand, it’s possible to distinguish between these states, aiding in early fault detection. Key algorithmic methods include supervised learning, unsupervised learning, and reinforcement learning.

Digital Twin

At LCM, the digital twin encompasses more than just the CAD model; it incorporates the physical behavior and the simulation of the entire model. This extensive simulation enables the generation of data also of operating states of which typically only limited measurement data is available, such as undesirable or infrequently occurring conditions. Consequently, the digital twin plays a crucial role in averting operational downtimes.

Domain Knowledge

Data can be sourced from measurement devices or created through system modeling and simulation, incorporating existing knowledge about the system. This approach not only generates a broader range of data but also enables the simulation of operating states that are rare or undesirable in normal operations.

Fault detection on ball bearings

Quality assurance using vibration measurement

In a gearbox-mounted ball bearing, faults are identified and categorized, ranging from “faultless” to “slightly damaged,” and up to “defective.” Using four key features, LCM’s solution achieves an impressive fault detection accuracy of 99%!

Generating Data via Fault Simulation

Obtaining fault data without operational downtime

Essential for identifying faults in components, machines, or systems, specific fault data can be effectively generated through the simulation of various fault scenarios. This approach is crucial in preventing undesirable operating conditions. Faults that are infrequent or never occur make AI training challenging, thus, simulation data proves to be exceedingly valuable.

Digital Twin for Predictive Maintainence

Tracking Component Lifespan through Monitoring

We’ve created a digital twin tailored for predictive maintenance, allowing us to accurately monitor and calculate the remaining service life of machine components, including bearings, actuators, and rotary clamps.

Our digital twin, grounded in simulation outcomes, computes non-measurable variables like the evolving contact pressure in bearings during production. Integrating virtual sensors with real-time measurements, it enables us to monitor the wear of various parts and accurately estimate their remaining useful life.

Measurement of hairline cracks using deep learning

Image-based quality assurance

Cracks are to be detected and measured on steel strips with a large data volume of 400 microscope images per sample. The cracks in the image are very thin, approximately 1 pixel wide. In addition, artifacts make crack detection difficult, which is why conventional image processing methods do not offer an exact and robust solution.

To develop an accurate and stable solution with minimal effort, 60 images were manually annotated, and supplementary training data from a publicly available dataset was utilized.

AI in practice: How and where to start?

Based on a study by McKinsey, the following steps can be taken to integrate AI into your own business:

1. Obtain a realistic picture

Separate the hype from feasible applications. Formulate use cases and prioritize them according to their degree of complexity and potential economic impact. Record the key framework conditions.

2. Build Core Technical Skills

The relevant specialist knowledge can be built up internally, but also with the help of external resources.

3. Utilize domain knowledge

This is used to describe use cases and dependencies and as part of the solution approach. Hybrid approaches integrate domain knowledge and can reduce the computing load, increase performance and improve reliability.

4. Establish a Database Early On

Continuously capture existing machine data, augment with additional data sources through retrofitting, and document faults carefully. Ensure to preserve faulty parts and systematically structure & annotate existing data and error scenarios to the fullest extent possible.

5. Step-by-step implementation

Initiating small, rapidly executable steps such as pilot projects, simulations, and test runs often involves minimal investment. These early stages can frequently be accomplished using existing data and adaptable sensor technology, including retrofitting and laboratory systems.
