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

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.

• 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
Some results from RA1Substrate preparation
• Edge radius: 0 – 0.1 mm; • Cutting depth: 0.1 mm; • Feed rate: 0.05 mm/O

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 insertIndustrial need: reduced cost of production by AM closer to final shape
Some results from RA1WP3: Industrial case studies: insert for a bracket to an office chair
