Abstract
In the machining process especially for the mold die of the instrument-panel for the cars among all those large-sized mold die, there is many part on the die where can not be finished to the final shape only by the milling process, because the shapes of the die are great ups and downs and very much complicated. hence. EDM process can be applied in many part of the injection mold die. In fact its process will greatly influence on the lead-time of the injection mold die. So; then we would like to explain about the application of EDM process for the injection mold die of the instrument-panel in this reports.
