Industrial cutting laser
Development of an on-line monitoring system for a high power industrial cutting laser
Our client asked:
TRUMPF provides manufacturing solutions in the fields of machine
tools, laser technology, electronics and Industry 4.0. It was looking
for an on-line monitoring system for a high power (10kW) industrial
The project story:
The challenge that was presented to us was that the lasers need
regular trimming in order to maintain their cutting efficiency, but any
sensor placed in the beam is instantly destroyed.
By monitoring the temperature on the rear of a silicon mirror, we
could infer the optical beam profile of the laser.
We created a sensor array as an array of diodes that could be
integrated into the fabric of the silicon mirror using standard
Algorithms converted the temperature array data into an accurate
representation of the laser beam’s optical profile.
Utilising a 2500 pixel MEMS optical beam sensor array, allowed rapid
set-up and continuous monitoring of the laser beam’s profile in order
to ensure consistent operation of that laser.
Results: deliverables and outcomes
TRMPF still uses this system to continually monitor and auto-trim
their cutting lasers.
Our consultants, scientists and engineers redefine what’s possible and help R&D groups across the medical, industrial, consumer and food and beverage sectors achieve commercial return from their opportunities.
We have completed over 10,000 projects for start-ups and global market leaders alike, from understanding the market & technology landscape through to developing and delivering complex products.
