Electrochemical Machining – a fascinating technology of net-shape fabrication

Electrochemical Machining (ECM) is a non-conventional technology to machine metals. The technology is based on the controlled anodic dissolution of metals. Thereby, the shape of the work tool (or cathode) is copied on the workpiece. The process works at very high current densities of a few hundred amps per square centimeters. The variants of ECM technology also employ high currents which are up to 1000 times higher in comparison with ECM e.g. electroplating. Due to the non-contact nature of the process, there is no mechanical stress on the workpiece. Additionally, the process is independent of the hardness of workpiece material which makes it suitable to machine difficult-to-cut materials.

Further advantages are listed below:

  • No significant thermal impact into the workpiece
  • No burr formation
  • Great versatility on geometrical requirements
  • High surface quality
  • Preserving material microstructure
  • No process-related tool wear

Unfortunately, ECM is still less popular in comparison with comparable non-conventional technologies like electrical discharge machining (EDM) and lasers. The INSECT has been established as an international forum for scientists and engineers working on ECM technology. This INSECT community offers a platform to exchange knowledge and share current challenges and experiences. The symposium reflects the current trends in ECM and covers wide topics on ECM processing, ranging from fundamental aspects like electrode reactions and dissolution mechanisms, simulation and modelling of ECM process to industrial applications, hybrid electrochemical processes and machine technology. Experts from industry and academia are invited to use this platform for discussion and networking to overcome new challenges of ECM technology.
