CNC Setup​/Machinist

Location:

W2002 COUNTY ROAD Q, Elkhart Lake, WI, 53020, United States

The CNC Setup/Machinist is responsible for setting up, proving out, and supporting production machining operations for aluminum castings within a foundry environment. This position focuses on fixture setup, establishing work and tool offsets, and verifying CNC programs to ensure repeatable, safe, and efficient machining processes. The Setup Machinist plays a critical role in transitioning aluminum cast components into consistent, in-spec finished parts by optimizing setups, minimizing scrap, and supporting operators during production runs.

• Set up and prove out CNC and conventional machining centers for production runs.
• Interpret process instructions, blueprints, GD&T, and customer specifications.
• Set up, align, and verify production fixtures, vises, chucks, and work‑holding devices for aluminum castings.
• Locate part datums and establish work offsets (machine zero and work zero).
• Set and verify tool lengths and tool diameter offsets.
• Load, verify, and edit CNC programs as required for setup, prove‑out, and optimization.
• Understand CNC programming fundamentals including coordinate systems, offsets, cutter compensation, feeds, and speeds.
• Perform first‑article inspections and make offset or tooling adjustments as required.
• Monitor machining processes to maintain dimensional accuracy and surface finish.
• Document measurements, checks, and process changes per quality requirements.
• Use precision measuring instruments including micrometers, calipers, height gauges, indicators, and pin gauges.
• Troubleshoot setup, tooling, fixture, and process issues to reduce downtime and scrap.
• Collaborate with engineering, quality, and supervision on process improvements.
• Assist in training and supporting machine operators during production.
• Perform routine machine and fixture inspections and maintain an organized work area.
• Safely move materials, castings, and tooling using forklifts, cranes, or carts (training provided).
• Follow all safety policies and participate in continuous improvement initiatives.

• High school diploma or GED required.
• Machining or technical certificate preferred.
• 2–5 years of CNC machining and setup experience in a manufacturing or foundry environment, or equivalent experience.
• Strong understanding of CNC machining setup procedures.
• Experience setting up fixtures and work‑holding for aluminum castings.
• Ability to find and set part zero using indicators, probes, edge finders, or manual methods.
• Knowledge of tool setting procedures and tool offset management.
• Working knowledge of CNC programming (G‑code) related to setup and prove‑out.
• Ability to read blueprints and apply GD&T principles.
• Proficiency in shop math, tolerances, and basic SPC concepts.
• Strong troubleshooting and problem‑solving skills.
