• Produce precision machined parts to tight tolerances (up to ±.0002”)
• Perform conversational program edits and adjustments to improve quality and efficiency
• Assist with developing programs, setups, and machining processes for new parts
• Select, install, and preset tooling including cutters, inserts, and tool holders
• Secure workpieces using fixtures, chucks, faceplates, or other holding devices
• Adjust speeds, feeds, offsets, and tooling as needed during production
• Inspect first-piece and in-process parts using precision measuring equipment
• Ensure parts meet all dimensional and quality requirements with minimal supervision
• Troubleshoot machining or setup issues and make corrections as needed
• Maintain coolant levels, machine fluids, and basic machine upkeep
• Organize materials and prepare upcoming jobs to reduce setup and downtime
• Operate secondary equipment during machine cycle times when applicable
• Cross-train and assist in other machining areas as needed
• Maintain a clean, safe, and organized work area
