          Automation does come in many different fl avors, so benefi ts can be realized for the  processing of low volume/high
          mix parts (job shop) or by high volume/low mix parts (production). In the EDM world, the most common automation
          method is to load and unload parts in and out of the machine using a standardized Work Holding Pallet system. This
          standardization and palletizing of the tooling helps to minimize processing variables through the use of off-the-shelf
          EDM tooling chucks that provide location and setup repeatability, and this tooling also establishes a consistent work
          holding interface that an automated robot arm can access.

          Implementing automation is like the next

          level of a video game…things may seem
          harder or more complex and confusing
          at fi rst! While it is human nature to fi ght
          or fear the unknown, once we understand
          and adapt to meet the next challenge,
          we learn new tricks and may shift our
          skillsets to achieve a new outcome.
          A shift in skillsets and routine defi nitely
          occurs with automation, as the opera-
          tor’s world may be turned upside down!
          An operator must openly embrace new
          controlled process methods and apply
          their abilities differently with automation.

          A few examples are the need for stricter
          programming, methodical and consistent
          process planning, and the use of ma-
          chine/robot scheduling functions to drive
          the system. Automation’s fl ow requires
          a change in the operator’s actions, as
          tasks must conform and be consistent to
          support the means to transfer the parts
          and programs to the Robot System.
