A Cost-Effective Way to Automate Industrial
Processes
M
BDA is one of the leading European
manufacturers in the aerospace and
armaments sector, specializing in the design
of missiles and missile systems for the
operational needs of the military. MBDA
France's Bourges site specializes in the
manufacturing tactical missile equipment.
The company wanted to automate certain
processes in small series or even single
unit production, by allowing an operator
with no programming skills to teach the
robotic system, in just a few seconds, the
process to be carried out, and then to execute
the cycle with complete confidence
without human supervision.
Fuzzy Logic's Repplix™ application
software module addresses all aspects of
this requirement in a cost-effective manner.
The first use case selected was the
tedious, manual cleaning of the molds
used to manufacture composites.
MBDA France's Bourges site produces
numerous small series of composite
parts that have to be molded. The speed
at which the robot operates is set directly
in the software. It can differ from the
speed in the learning phase. This operation
is complex: The parts to be treated
are diverse and numerous and in each
series, the level of residue to be stripped
off, and its location may vary. This
method of operation is tedious, and it
also requires protecting the operator
from exposure to toxic substances.
According to Vincent RAFIN, Head of
the Factory of the Future Project at
MBD, " At MBDA we look for agility
when it comes to robotization. We want
to robotize tasks which cause musculoskeletal
disorders in our operators, and
which occur in certain cases in the production
of very small series or even single
parts, so we need to keep the non-recurring
costs of programming as low as
possible. Programming a robot to define
the trajectories of a laser is not the right
approach for small series production, it
is time-consuming and costly, and has to
be done by a roboticist. "
For advice, MBDA turned to Meliad, a
recognized expert in the aerospace industry
for surface preparation and laser
stripping, and to Staubli. The latter recommended
Fuzzy Logic for its universal,
visual programming solutions. Fuzzy
Motion Design, June 2022
The operation is tedious and requires protecting the operator from exposure to toxic substances.
The speed at which the robot operates is set directly in the software. It can differ from the speed in the learning
phase.
Logic developed Repplix™, an extension
of its Fuzzy Studio™ software, in
cooperation with MBDA.
A portable learning device, controlled
by the operator using his knowledge of
the application task, teaches the
Repplix™ software the first laser alignment.
A monitoring function, performed
via a real-time digital twin of the
robotic installation created in Fuzzy
Studio™, takes into account collision
monitoring and trajectory feasibility in
the robot´s environment. Alert parameters
are set up. Trajectory capture combines
several process parameters, such as
laser triggering and power. The operator,
who is not a roboticist, is also able to
modify the trajectory and process parameters
via the graphical interface,
even after the learning phase.
Then, from this digital twin, the cycle
is launched and the robot moves with
the laser, guided by the accurate capture
of the trajectory learned from the operator.
The speed at which the robot operates
is set directly in the software. The
cycle is performed autonomously by the
robot, without the need for operator supervision.
The same process, which takes
only a few minutes, is done for each new
series of molds.
Repplix™ can automate industrial processes
like these. The solution developed
in this way, is executed with millimeter
