A Day in the Life

You’ll start your shift by reviewing engineering drawings and work instructions, prepping tooling and fixtures, and setting up 3-, 4-, or 5-axis CNC mills for the day’s runs. You’ll load material, align workpieces, and verify offsets. As the first chips fly, you’ll monitor feeds and speeds, adjust as needed to hold tight tolerances, and complete in-process checks with micrometers, calipers, height gauges, and other precision instruments. When a feature demands it, you’ll read GD&T callouts, confirm true position, and collaborate with engineering or programming to troubleshoot and optimize. Throughout the day, you’ll perform routine machine care, maintain a clean and safe work area, and finalize parts with thorough inspections before they move to the next operation.

What You’ll Do

• Set up and operate CNC milling machines (3-axis, 4-axis, or 5-axis as applicable)
• Interpret blueprints, engineering drawings, and work instructions
• Install tooling, fixtures, and workholding; load materials and verify alignment
• Monitor machining processes; adjust parameters to maintain tolerances
• Conduct in-process and final inspections using precision measurement tools
• Troubleshoot machining issues; partner with engineering/programming as needed
• Perform routine machine maintenance and keep equipment in top condition
• Uphold a clean, organized, and safety-first workspace

What You Bring

• High school diploma or equivalent; technical/trade school preferred
• 2+ years of CNC milling experience in a manufacturing environment
• Solid grasp of milling operations, tooling, feeds/speeds, and materials
• Ability to read blueprints and apply GD&T
• Experience with CNC controls
• Proficiency with precision measurement and inspection methods
• Strong attention to detail and problem-solving ability
• Comfort working independently and within a collaborative team

Physical & Environment

• Stand for extended periods; lift up to 50 pounds
• Good hand-eye coordination and manual dexterity
• Manufacturing setting with machinery, noise, and metalworking fluids
• PPE required at all times on the shop floor

Your Core Toolkit

• GD&T; Blueprint Reading
• G-Code and M-Code fundamentals
• CNC Machine Setup & Changeover
• CNC Tooling; Equipment Troubleshooting; Troubleshooting Skills
• Precision Measurement & Hand Metrology
• Advanced Inspection & Gauge Measurement
• Machine Setups for Production Runs
• Aerospace Manufacturing experience

Machines & Technologies You’ll Use

• CNC Mill (3-4 axis VMC) (Fanuc, Doosan, Dmg Mori Seiki, Okuma)
• 2D Drawings
• CNC Mill (5+ axis VMC) (Fanuc, Okuma, Dmg Mori Seiki)
