CNC Programmer & Pattern Maker - Precision Tooling

TriEnda Holdings, LLC; Portage, Northern (WI, KY); Hybrid; USD 65,000 - 90,000; Full time

Job summary

Kruger Family Industries in Portage, WI is seeking a skilled CNC Programmer / Pattern Maker to lead in-house pattern builds from start to finish. You will manage Cam programming, set up 3-axis and 5-axis CNC routers and mills, and ensure production-ready thermoforming plugs from wood, Ren Shape tooling boards, and aluminum molds.

Responsibilities include drafting, venting, post-processing, inspection with calipers and micrometers, and collaboration with design engineering to implement changes

Qualifications

• 3+ years of experience in CNC machining, pattern making, mold making, or precision tool/die fabrication.
• Proven experience machining and working with a wide range of materials, including wood, Ren shape/tooling board, ABS plastics, and metals (cast aluminum).
• Proven track record setting up and running CNC mills or large-format routers. Strong traditional model shop bench-work skills are essential.
• Strong ability to read 3D engineering files, blueprints, and GD&T.

Responsibilities

• Wood & Ren Board Fabrication: Build, construct, and CNC machine master patterns, plugs, and molds from scratch using hardwood, plywood, Ren Shape/polyurethane tooling boards, and epoxy.
• CNC Machining of 3D Printed Tools: Set up and operate 3-axis and 5-axis CNC routers and mills to precisely machine, trim, and finish 3D-printed polymer patterns into production-ready thermoforming plugs.
• Aluminum Mold Maintenance & Modification: Modify, repair, and rework existing cast aluminum molds when engineering changes or production wear require updates; perform precise drilling, milling, and manual bench work on aluminum tooling.
• Post-Processing & Surface Finishing: Sand, fill, polish, and apply heat-resistant coatings to machined 3D prints, wood, Ren board, and aluminum surfaces to achieve optimal, defect-free finishes.
• Apply Draft & Venting: Inspect all tooling to guarantee proper draft angles for clean part release, and drill or clear precise vacuum vent holes to optimize production airflow.
• CNC Programming & G-Code: Load, test, and optimize CNC programs; perform basic G-code edits at the controller to accommodate variations in wood, printed polymers, and cast aluminum.
• Inspect & Verify: Use calipers, micrometers, and depth gauges to inspect finished tools, ensuring they maintain tight engineering tolerances (± 0.005").
• Engineering Collaboration: Partner with the on-site design engineering team to provide feedback on 3D print machining allowances, material stock, and aluminum mold design updates.
• Perform all duties in compliance with regulatory requirements as well as company policies and procedures
