EDM Machinist

ADVANCED ENGINEERING AND EDM; California (MO); On-site; USD 65,000 - 90,000; Full time

Job summary

ADVANCED ENGINEERING AND EDM is seeking an experienced EDM Operator/Machinist to join our precision machining team. You will set up and operate Wire EDM and HP EDM machines for production and prototype runs, analyzing engineering drawings and GD&T to verify parts meet specifications.

You will also write and edit NC programs for EDM control systems, perform in-process inspections with micrometers, CMM, and optical comparators, and maintain equipment logs.

Qualifications

• Completion of EDM operator/machinist training or apprenticeship.
• 3+ years of hands-on experience operating both Wire EDM and HP EDM machines in production or precision manufacturing.
• Ability to write and edit NC programs on EDM control systems (Wire and HP).
• Proficiency reading engineering drawings with GD&T per ASME Y14.5 standards.
• Experience holding tolerances of ±0.0002" or tighter on EDM-machined parts.

Responsibilities

• Set up and operate Wire EDM and HP EDM machines for production and prototypes.
• Read, interpret, and program using NC/CNC EDM code specific to EDM control systems.
• Select wire types, diameters, and tension settings per material and tolerance requirements.
• Perform in-process inspection using micrometers, CMM, optical comparators, and surface finish gauges.
• Maintain machine electrode wear logs, dielectric fluid levels, and filter change schedules.
• Troubleshoot EDM-specific issues and ensure finished parts meet customer specs.

Duties and Responsibilities

• Set up and operate Wire EDM machines (such as Mitsubishi and Current) for production and prototype runs
• Set up and operate HP EDM machines, including electrode selection, dielectric fluid management, and gap control
• Read, interpret, and program using NC/CNC EDM code specific to EDM control systems — not general G-code programming
• Select appropriate wire types, diameters, and tension settings based on material and tolerance requirements
• Interpret engineering drawings, GD&T callouts, and 3D models to verify part conformance
• Perform in-process inspection using precision metrology instruments including micrometers, CMM, optical comparators, and surface finish gauges
• Perform secondary operations including deburring, cleaning, and surface preparation specific to EDM-produced parts
• Maintain machine electrode wear logs, dielectric fluid levels, and filter change schedules
• Troubleshoot EDM-specific issues including wire breakage, surface finish defects, and electrode wear deviation
• Ensure all finished parts meet customer specifications and internal quality standards

Minimum Requirements

• Completion of a formal EDM operator/machinist training program or apprenticeship — general CNC machinist training without EDM-specific curriculum does not satisfy this requirement
• Minimum 3 years of hands‑on experience operating both Wire EDM and HP EDM machines in a production or precision manufacturing environment
• Demonstrated ability to write and edit NC programs on EDM control systems (Wire and HP)
• Proficiency reading engineering drawings with GD&T per ASME Y14.5 standards
• Experience holding tolerances of ±0.0002" or tighter on EDM-machined parts
• Experience with precision inspection equipment: micrometers, height gauges, CMM, and optical comparators
• Ability to perform all secondary operations associated with EDM‑produced parts (deburring, cleaning, rust prevention)
• Physical ability to stand for extended periods, lift up to 50 lbs, and work in a manufacturing environment
