Net Shape Manufacturing

There is an increasing need for more complex, higher performing products at lower cost, particularly in the high value manufacturing sectors. Additive Layer Manufacturing (ALM) and Machining Technologies are two tools that can deliver these high performance products at an affordable cost and with short lead-time.

The ALM team, headed up by Dr Greg Gibbons, conducts research into both the exploitation and development of ALM (3D Printing) technologies to provide real world solutions to industry. ALM enables the resource efficient manufacture of products, offering significant time and cost savings and increased product functionality through complexity of design, and multi-material functionality.

The Machining Research team headed by Professor Stuart Barnes has experience in all classes of cutting tool materials from high-speed-steel to polycrystalline diamond. The excellent facilities available in WMG (machining centres and analytical equipment) enables the machining characteristics of workpiece materials, cutting tools and cutting fluids to be precisely determined.

Facilities

The ALM team has a strong background in research, development and technology transfer of ALM, Rapid Prototyping and Rapid Tooling technologies into many sectors, including aerospace, automotive, healthcare and defence. Facilities include:

  • Connex 260 multi-material 3D printer: Enables the manufacture of polymeric components and assemblies with multi-functionality.
  • Fortus 400mc ALM system: Capable of manufacturing large-scale components in a range of thermoplastics, including high HDT polymer.
  • ZPrinter 450 colour 3D Printer: Provides the capability to print full-colour 3D models and assemblies.

WMG has always been involved in machining research. Over the years research work has been carried out for a wide variety of organisations involving the machining of a wide range of metallic and some non-metallic materials.

WMG’s partnership with DMG / MORI SEIKI ensures that the machining facilities always represent the state-of-the-art in machining technology and the capability has been significantly extended with the recent acquisition of the Ultrasonic 65 Monoblock machine which will provide ultrasonic and ultrasonic assisted machining capability. A DMC 1035 V ecoline and DMU 40 eVo linear system are also available.

Other key facilities include:

  • Kistler dynamometer for precise measurement of cutting forces
  • Optical and scanning electron microscopy facilities available for the accurate measurement and characterisation of tool wear.
