Chicago - Make plans to attend the IMTS 2014 Conferences to learn about Re-evaluating the EDM Process.
- Date: Monday, September 8 from 11:00 AM - 11:55 AM ROOM: W-194B
- Speaker: Ken Baeszler, Product Manager, GF Machining Solutions
Until recently, many manufacturers of titanium components have considered electrical discharge machining (EDM), either completely off limits, or to be used as a primary process coupled with a secondary operation. Many times, the secondary operation is solely in place to remove the parent material damage caused by the thermal process of EDM. Recent improvements in electronics have led to the development of new “clean” EDM generators that substantially reduce the heat affected zone and micro-cracking caused by the thermal removal of material. In addition to research completed at AgieCharmilles, independent studies are cited from the University of Birmingham that provides evidence supporting the re-evaluation of the EDM process, including:
- Improved EDM technology processes
- A review of EDM surface integrity results showing reduced heat affected zone and near zero recast layer and residual stresses.
- Fatigue resistance tests comparing the EDM process with the milling process.
- Alternative wire electrode materials (coated, pure steel) showing improvements in cutting speed and elimination of Zn and Cu contamination.
- Ability to control the thickness of the oxide layer through manipulation of the generator spark characteristics.
Today’s clean EDM technology opens up new avenues of manufacturing for many titanium applications. Intricate parts can now be designed with the EDM process in mind, thus reducing tooling and material cost, improve deliveries and eliminate secondary operations.
The educational and informative conferences run Sept. 8-11, 2014 in the West Building, Level 1. To register for this or any session, visit http://www.imts.com/education/imtsconference.html.
