Pre-Conference Workshops

Tuesday, May 6

9:00 a.m. – 5:00 p.m.
(Note: Time includes the Keynote Presentation beginning at 9:00 a.m.)

(You may select one workshop from the choices listed below.)

Note: Both workshops include coffee, lunch voucher, and free admittance to the Mfg4 exhibits, show floor education and industry keynotes.

Metrology: Quality Control for Medical or Micro components

WORKSHOP LEADER: Thomas Kurfess, Georgia Institute of Technology

How do you know you’re getting the measurements you need? Depending on what you’re measuring and the technology you’re using, you may be getting what you expect or something completely different. With a focus on highly precise small to micro measurements, this workshop will help you use what you have better and to understand if another system might be better for your needs. Topics covered include:

  • Feature-based metrology
    • Least squares fit
    • Minimum/maximum
    • CAD model comparison
  • Dimensional metrology—both rigid and flexible components/devices
  • Surface finish
  • Uncertainty
  • Data analysis
  • Comparisons of when to use which technology
  • Technologies covered include:
  • CMMs
  • Non-contact systems
    • CT scanning
    • Laser coupled with vision
    • SEM
    • AFM
    • Confocal microscopy
    • White light interferometry
    • Video metrology

MicroManufacturing Fundamentals

WORKSHOP LEADER: J.Rhett Mayor, Georgia Institute of Technology


Introduction to the Workshop

  • Highlights of some key issues that will be discussed

Introduction to Micro Machining: Mechanical Removal and Ablative Removal Processes

  • Differences between micro machining, subtractive processes, and MEMs-type processing, particularly with respect to materials classes, features size, and relative precision
  • Overview of existing micro machining processes considering mechanical material removal processes (micro milling, micro turning, etc.) and including micro milling, micro turning, micro- and ablative removal processes (laser, ion beam, electron beam)

Introduction to Micro Machining: Electric discharge and Electrochemical Removal Processes

  • Overview of existing micro EDM capabilities
  • Comparison to other micro machining processes including size and material capabilities

Introduction to Micro Molding: Current Processes and Techniques

  • Overview of existing micro molding technologies including injection molding, insert molding, and two shot molding
  • Differences beyond size between micro molding and traditional molding

Introduction to Micro Forming: Current Processes and Techniques

  • Overview of existing micro forming technologies
  • Size effects in micro forming, differences between micro forming and macro forming

Introduction to Fixturing and Workholding

  • Overview of existing technologies
  • Capabilities and limitations of existing fixturing and workholding tools

Micro/Meso Metrology: Characterizing Micro/Meso Products

  • Review of metrology techniques suited to the needs and requirements of micro/meso scale manufacturing
  • Capabilities and limitations of micro/meso scale metrology tools, including contact and probe techniques, CMM, SEM, TEM, AFM, and various interferometric approaches including scanning white light interferometry (SWLI)
  • Application examples of SWLI metrology

Current State of Micro/Meso-scale Machining and Machine Tool Systems Research

  • Overview of ongoing research and commercially available miniaturized machine tools and micro-factory production systems.
  • Initial investigations on the dynamic stability of micro-scale machining operations will be highlighted with examples of micro/meso-scale cutting operations.
  • An assessment of miniaturized machine tool system technologies for the manufacture of high accuracy micro/meso-scale components and devices will be presented.
