Job Description

Job Description

The CNC Mill Setup Machinist is responsible for performing complete machine setups and operating 3-axis, 4-axis, and 5-axis CNC milling machines in a high-mix low-volume aerospace manufacturing environment. This role requires expertise in reading blueprints, GD&T, precision inspection tools, setting work offsets, program editing, and holding tight tolerances on aerospace materials.

Responsibilities

• Perform complete machine setups on 3-axis, 4-axis, and 5-axis CNC milling machines.
• Read and interpret aerospace blueprints, engineering drawings, GD&T specifications, and process routing sheets.
• Select, assemble, and install cutting tooling, specialized fixtures, and work holding devices.
• Set work coordinate systems, work offsets, and tool height offsets accurately.
• Verify First Article Inspection (FAI) parts and make necessary machine control adjustments.
• Monitor machine performance, cutting tools, feeds, speeds, and dimensions to hold tight tolerances during production runs.
• Inspect aerospace components using precision measuring equipment including calipers, micrometers, bore gauges, height gauges, and hand inspection tools.
• Troubleshoot machining issues, tool wear, and setup errors, making G-code and M-code program edits directly at the machine control as needed.
• Maintain quality documentation and job records in compliance with AS9100 quality management standards.
• Collaborate with CNC programmers, quality inspectors, and manufacturing leadership to support on-time delivery schedules.

Qualifications

• Minimum 5 years of experience in CNC mill setup and operation within the aerospace manufacturing industry.
• Proven track record of independently setting up and operating 3-axis, 4-axis, and 5-axis CNC milling equipment.
• Strong proficiency in blueprint reading, technical engineering drawings, and Geometric Dimensioning and Tolerancing (GD&T).
• Demonstrated ability to hold tight tolerances on complex aerospace components.
• Hands-on experience machining aerospace materials including aluminum, stainless steel, titanium, Inconel, 300M, and tungsten.
• Proficiency with standard precision inspection equipment, First Article Inspection (FAI), and quality control procedures.
• Working knowledge of Haas, Brother, Makino, Matsuura, DMG Mori, or similar multi-axis CNC machine controls.
• Familiarity with AS9100 quality management systems and aerospace industry standards.
• Ability to edit CNC programs at the machine control and optimize tooling strategies, feeds, and speeds.
• Experience working in high-mix low-volume aerospace precision manufacturing environments.
• Strong technical troubleshooting skills, problem-solving ability, and attention to detail.

What We Offer

• Competitive pay based on experience.
• Overtime opportunities.
• Comprehensive health insurance benefits package.
• Stable career opportunities within a growing aerospace and defense manufacturer.
• Opportunity to work on critical defense and aerospace programs.
• Team-oriented manufacturing environment focused on continuous improvement and career advancement.
