Lasers are the ultimate example of the tool for Industry 4.0. As well as transforming data directly into shapes, they also provide a wide variety of measurement and operating data for the digital process chain in smart factories.

A laser machine can record data on all these aspects of its operation − and more besides. It can pass on this data within a smart factory to facilitate various tasks, including monitoring production, assuring in-process quality control, comparing parameters with similar machines in large manufacturing networks, providing early warnings of possible malfunctions, and evaluating production planning figures.


Quality assurance

Assigning component IDs from laser and process data enables automated backup & seamless tracking of quality data. Bad parts are identified in real time when they deviate from defined process parameters – these parts are then tracked via their IDs and culled. Analyzing the deviation reports helps to systematically recognize errors and optimize process parameters.


Transparency

Using easy-to-understand dashboards, operators can determine the status of every machine in the entire pool with just a glance.  Events and changes in condition are automatically sent to the correct recipient. Status-based maintenance information, for instance, are sent only to the maintenance personnel, while manual programming procedures are visible to application managers.


Early warning

In addition to visualizing the current status, algorithms can be used to analyze condition data. Recognizing trends and patterns helps to identify faults early and to inform the person responsible before a failure occurs. Using the calculated prediction times, maintenance can harmonize repair measures with the production plan.
