• Optimize programs for accuracy, surface finish, cycle time, and tool life.
• Prepare and interpret sketches, 2D/3D CAD data, and detailed job instructions.
• Inspect machined components to ensure tight tolerances before releasing to the next stage.
• Complete documentation and paperwork for mold assembly and job tracking.
• Operate multiple machines and assist with shop support tasks such as shipping/receiving when needed.
• Maintain a clean, organized, and safety-focused work environment.
• Communicate machine issues, tooling needs, and workflow updates to supervisors and team members.
