CNC Setup/Machinist

Location: W2002 COUNTY ROAD Q, Elkhart Lake, WI, 53020, United States SUMMARY 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. SSENTIAL DUTIES AND RESPONSIBILITIES 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. QUALIFICATIONS 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. #J-18808-Ljbffr
