Job Description

The Machine Shop EDM machinist is responsible to execute precision machining using EDM Wire Cut, Super Drill, and Die Sinker to fabricate and modify parts, tools, and dies per engineering drawings and quality standards

• Set up, program (where applicable), and operate EDM Wire Cut, EDM Super Drill, and EDM Die Sinker per job travelers and technical specs.
• Interpret engineering drawings/3D models; select electrodes/fixtures; define optimal cutting strategies (offsets, flushing, burn parameters).
• Verify part conformance using precision instruments (micrometers, calipers, height gauge, gauge blocks, profile projector/vision system); document results.
• Perform first‑article verification and adhere to in‑process inspection checkpoints and control plans.
• Optimize cycle time, surface finish, and dimensional accuracy; recommend parameter/tooling improvements.
• Conduct routine maintenance (alignment checks, wire path, guides, dielectric/flushing, filtration) and escalate abnormalities promptly.
• Coordinate with CNC/Lathe/Grinding cells for multi‑process jobs; ensure correct hand‑off and traceability.
• Comply with 5S, safety, ESD (if applicable), LOTO, and IMS/QA procedures; complete job travelers and production logs accurately.
• Support Kaizen, TPM, and LSS activities; contribute to cost‑down and scrap reduction initiatives.

• Completed any Technical course
• At least 4 years related experience
• EDM process expertise (work holding, electrode selection, burn/wire parameters, heat‑affected considerations, flushing).
• Proficient in blueprint reading (GD&T), tolerancing to ±0.005 mm (as required by job), and surface finish requirements.
• Metrology proficiency: micrometer, bore gauge, dial test indicator, height gauge, surface roughness check, and vision/Quick Vision systems.
• Basic CAD/CAM literacy (reading models, setting offsets, importing programs) is an advantage.
• Strong troubleshooting on taper/kerf compensation, wire breakage, arcing, recast, and electrode wear.
• Safety, quality, and documentation discipline.
