How a dedicated terminology infrastructure kept DE>FR HMI strings consistent across multiple batch deliveries for a high-power laser manufacturer.
The client
A manufacturer of industrial precision laser processing systems supplying production facilities across European markets. The machine control interface and supporting HMI documentation are operated by French-speaking production teams working directly with high-power laser equipment in live manufacturing environments.
The challenge
An industrial laser system’s HMI isn’t a general-purpose software interface. Every string on the operator panel, be it a safety state label, a laser output parameter, or a process threshold value, has direct operational consequences. The French rendering of a German source term has to be unambiguous at a glance; an operator can’t pause to interpret an unfamiliar label while managing live equipment.
The languages in question made things more complicated. The source language was German, not English, which meant the project required verified DE>FR terminology equivalences rather than the established EN>FR baselines that most localization workflows reference. Domain-specific terms for laser safety classifications, beam parameters, and machine operating modes required careful terminology decisions be made with no ready-made French precedent.
The project was structured as a series of batches delivered across an extended period. Without a consistent terminology and translation memory infrastructure from the outset, there was a risk that each batch would introduce new inconsistencies, a particular concern for safety-critical labels that have to mean the same thing every time they appear on the operator panel.
The solution
Before the first batch was translated, we established a dedicated DE>FR master translation memory and a domain-specific termbase covering laser safety states, process parameters, machine operating modes, and operator alert messages. Every approved French rendering was locked from that point forward, with no re-translation of validated entries across subsequent batches.
HMI string translation was handled with direct reference to the on-screen character constraints of the display hardware. Each string was reviewed against its source-code context rather than in isolation, confirming that the French rendering would fit accurately within the interface layout. Where character limits required compression, terminology precision took precedence.
The results
- Dedicated DE>FR master TM and domain-specific termbase built before batch 1 and maintained throughout, covering laser safety states, process parameters, and operator alerts, leading to consistent French output for every batch.
- HMI strings reviewed against display hardware constraints and source-code context, ensuring accurate spatial rendering within the operator interface layout.
- Repeat-delivery structure enabled the TM to be leveraged across incremental HMI updates, reducing turnaround time on new string batches while making sure they were fully consistent with all previously validated content.
