Robust and Adaptive Manufacturing Systems
Implications of the concept of the constantly changing manufacturing system for:
New design methods: symbolic communication between machines/devices. For such
communication, both software and hardware of present equipment must be extended.
Develop and integrate new agent-oriented design tools: systems, e.g. assembly systems,
capable to work in not well structured environment.

Define handling characteristics for non-rigid materials
Advanced Process Control and Predictive Maintenance
Sensor and sensor system development and integration for measurement of critical
process parameters: Sensor networks capable of acquiring symbolic data

Results from RA 1
WP2 Advanced Process Control and Predictive Maintenance
1.
Flexible, automated sewing further developed:
+ A software has been developed for integration of control of robot,
PyMoCo and ROS
+ Real time control has been tested and promising results have been
achieved for 8 milliseconds control.
+ A new speed sensor (mechanics and electronics) has been developed.
The sensor will be used for measurements required for further
development of the control system for the sewing cell.
= Sew together parts of different shapes and materials, without prior
knowledge of the part geometries
2.
A predictive maintenance model has been established in order to
obtain optimal maintenance scheduling based on the condition of
the equipment.
3.
RFID techniques in condition monitoring has been researched,
and a demo of RFID application in production system has been
established.
4.
A dual arm robot installation is being built

International collaboration within RA1 in
2012:
Chairman from Industry for Joining Sub-Platform: SFI Norman and SINTEF Raufoss Manufacturing AS
have worked actively in Manufuture by participating in the HLG. As a result Kristian Martinsen now holds
the chair, as an industry representative, for the new sub-platform for Joining.
Exchange agreement with four students from Ensiame Engineering School, Valenciennes, France. Have
been working on design of a flexible jig for assembly of components for Sandvik Teeness and a dual arm
robot installation.
Collaboration through the development of the new ISO standard on additive manufacturing technology
does now include the chair for ISO/TC261 WG1 Terminology for additive manufacturing.

integrated sensors and new business models for injection molding industry.
Two new EU-projects have been granted, SASAM and Diginova, where SINTEF Raufoss Manufacturing is
a partner. Diginova, short for Innovation for Digital Fabrication, is a coordination and support action
project under NMP 7th FP, Networking of materials laboratories and innovation. SASAM, which is short
for Support Action for Standardisation in Additive Manufacturing, is a similar type of project.
Collaboration on a EU-proposal "VITAMIN", where Sandvik Teeness was partner together with SRM and

Some results from RA1
Substrate preparation
• Flat milling produces a glossy surface;
– Low-friction for powder spreading
– Reflective to laser beam
• Standard procedure: Sand blasting, -unsuitable for the
hybrid cell
• Hybrid cell procedure: Extra sharp cutting tool inserts
"scratch" the substrate
– Provides an exact z = 0 -point for starting the AM building
• Edge radius: 0 – 0.1 mm;
• Cutting depth: 0.1 mm;
• Feed rate: 0.05 mm/O

Some results from RA1
WP3: Industrial case studies: insert for a bracket to an office chair
Results:
• Cooling time for conventional insert and “old” design 70 sec.
– Estimated cooling time with new design approximately +25 sec. = 95
sec.
• Cooling time with new design and conformal cooling insert: 48 sec.
• Cost of machining AM produced insert similar to conventional
production, however the cost of AM makes this an expensive insert
Industrial need: reduced cost of production by AM closer to final shape
