Tokyo (SCCIJ) – Reishauer, the Zurich-based machine tool specialist, has developed an automatic component diagnosis based on artificial intelligence to monitor its continuous generating gear grinding machines. They are mainly used by the automotive industry to produce transmission parts. In Japan, Reishauer operates from Shin-Yokohama.

Cloud-based application

The application named “Argus AI” detects changes in machine components such as wear and tear. Using an array of sensors, the automatic component diagnosis program can determine whether any machine components have undergone even tiny changes. Argus AI then independently reports the assessments to an associated cloud-based web app. The app presents the reports in the form of a simple color and indicator display.

This real-time information enables the machine users to reduce unplanned interruptions and downtimes and to harmonize service and maintenance processes. The affected component can be identified quickly and efficiently before being exchanged. “Service and maintenance tasks can be planned more effectively”, Reishauer explained in a press release. All features utilize “machine-learning” algorithms.

Close-up monitoring

Argus AI consists of several parts. “Argus Cloud” stores a “digital twin” of all process data of the machine’s component status and makes them accessible for immediate process analyses and optimizations. The features of the program enable an immediate assessment of the overall equipment effectiveness as well as the complete traceability of gears, including their process data and component states.

“Argus Machine” continuously monitors the dressing processes as well as the roughing and finishing operations of the gear grinding machines. The generated data is analyzed and instantaneously evaluated based on static and dynamic criteria. Gears with geometrical quality deviations from pre-machining are detected and removed from the process.

Technological leader

Reishauer, founded in 1788 in Zurich, launched the first continuous generating gear grinding machine in the world already in 1945. Globally, the majority of hard-finished gears are precision-ground on Reishauer machines. The machines use twin spindles which not only markedly shortens cycle time. This technology also ensures a high production output: While one part is being ground, a new part is loaded and meshed simultaneously into the grinding position.

The in-house developed electronic gearbox coordinates the complex axes movements of the continuous generating grinding process and creates the exact geometry of the gear. For decades, continued focused development of the grinding process has given Reishauer the technological lead in the hard-finishing of gears. To name but a few examples: high-speed grinding with 100 meters per second, polish grinding, and topological grinding. Moreover, Reishauer automation supports any type of part supply system.
