Digitalization, visualization, analysis and optimization of machining processes

In machining production today, tools and tool holders are mostly used without sensors. As a result, any quality defects caused by wear can usually only be detected after the machining process on the workpiece itself or through failures.

With iTENDO, Schunk has developed an intelligent tool holder with integrated sensors that can be used as a retrofit in existing machines. This enables the measurement of process stability and autonomous process optimization through real-time capable data communication, process analysis and parameter optimization.

In order to digitize, visualize, analyze and optimize the iTENDO data and the associated workflows, elunic was commissioned to contribute its experience in the IIoT area and the various IIoT platforms. elunic supports SCHUNK in the realization of the iTENDO application, from conception and design to development, operation and initial field tests. In order to achieve a quick start and the most efficient results possible, the elunic shopfloor.io-IIoT software modules were used in development, which provide a basis for white label IIoT solutions for machine manufacturers.

iTendo - Prozessüberwachung

Added value through the Schunk iTendo platform

Control, analysis and optimization of production processes in real time.

The collected data serves as the basis for machine learning-based process monitoring.

Operation is possible both in the cloud and purely on-premises.

Notification of the machine operators in the event of fault conditions.

Remote monitoring of distributed systems via a mobile application.

"elunic has enhanced our hardware and process expertise with their experience in developing IIoT software and architectures. By bringing together these different components and expertise, we were able to create a platform that will be used as the basis for further intelligent products and digital services from Schunk."

iTendo apps and functions

Dashboard

Schunk iTendo platform

The dashboard serves as an entry point into the iTENDO platform and overview of the most important data from the respective apps and selected tool holders.

Watch

Schunk iTendo-Plattform - Watch App

Thanks to the Watch app, live data from the iTENDO feed and speed values can be viewed in real time.

Alarm

Schunk iTendo-Plattform - Alarm App

In the alarm app, limits can be set for notifications within a defined device hierarchy and error messages can be analyzed.

Record

Schunk iTendo-Plattform - Record App

The Record app can be used to record live data on the feed and speed values of the tool.

Trend

Schunk iTendo-Plattform - Trend App

Recordings from the Record app are displayed within the Trend app to identify trends that lead to errors (such as drill breakages).

iTendo application examples

iTendo Bohrsenken

Drill sinks

The iTENDO monitors compliance with the surface quality when countersinking holes. In this application, monitoring the countersinking process is used for quality and process control and to document function-critical features.

iTendo - Bohrer Verschleißerkennung

Drill wear detection

A drill with a diameter of < 0.9 mm is difficult to monitor due to its low cutting forces. The challenge is to detect wear (wear trend) and replace the tool before it breaks.

Watch video
iTendo - Automatisiertes Nachstellen von Bürsten

Automated adjustment of brushes

The edges on a workpiece surface are deburred using a brush operation. As the brush wears, the infeed must be readjusted. The iTENDO enables automatic adjustment.

Watch video
iTendo - Adaptive Schwingungsregelung

Adaptive vibration control

When milling a workpiece, the cutting conditions change depending on the changing workpiece contours. Chatter marks on the component can be avoided by adaptive control at the transition from different web widths.

                                    After the first screening, we will send you an invitation to our Talentcube tool. We have prepared 3-5 short questions that you can answer in a personal video (we have also prepared a short introduction video). If you don't feel comfortable with this, please let us know - we'll find an alternative!

                                    We want to get an authentic first impression of you and at the same time have the opportunity to review your video with our team and make the right decisions quickly.
