Industry & Occupation
Classification
Summary
A job that uses electrodes to perform electrical discharge machining on metal parts, creating high-precision shapes and fine processing. Operates wire EDM or sinker EDM machines to finish parts according to drawings.
Description
EDM operators are skilled technicians who precisely machine metal parts using electrical discharge machines (wire-cut EDM or sinker EDM). They select electrode materials and shapes according to the material and shape of the workpiece, and set machining parameters (current, voltage, pulse width, etc.). They read drawings, create and adjust machining programs, and after machining, inspect dimensions using calipers or micrometers to confirm quality. High attention to detail, measurement skills, and machine operation skills are required.
Future Outlook
With the increasing precision and shift to small-lot, multi-variety production in manufacturing, demand for precision EDM remains stable. Introduction of IoT and automation technologies will advance machining programs and process design, requiring skill enhancement for technicians.
