Job Description

A CNC (Computer Numerical Control) Programmer creates, modifies, and optimizes programs that control CNC machines used to manufacture precision parts and components. They work closely with engineers, machinists, and production teams to ensure parts are produced accurately, efficiently, and according to specifications.

Key Responsibilities

• Interpret engineering drawings, blueprints, CAD models, and technical specifications.
• Create and edit CNC programs using G-code, M-code, and CAM software.
• Select appropriate cutting tools, fixtures, and machining strategies.
• Set up and test CNC programs on milling machines, lathes, routers, or multi-axis machining centers.
• Optimize machining processes to improve quality, reduce cycle times, and minimize material waste.
• Troubleshoot programming and machining issues.
• Perform first-piece inspections and verify dimensional accuracy.
• Maintain documentation of programs, tooling, and setup procedures.
• Collaborate with manufacturing engineers and machine operators to improve production efficiency.
• Ensure compliance with safety and quality standards.

Required Qualifications

• High school diploma or equivalent; technical certification or associate degree preferred.
• Experience programming CNC machines in a manufacturing environment.
• Proficiency with CAD/CAM software such as Mastercam, Fusion 360, or SolidCAM.
• Strong understanding of G-code and machining principles.
• Ability to read blueprints and GD&T (Geometric Dimensioning and Tolerancing).
• Knowledge of tooling, cutting parameters, and material properties.
• Strong problem-solving and analytical skills.

Preferred Skills

• Experience with 3-axis, 4-axis, or 5-axis CNC machining.
• Familiarity with quality inspection equipment such as CMMs, micrometers, and calipers.
• Lean manufacturing or continuous improvement experience.
• Knowledge of machining metals, plastics, and composite materials.

Typical Work Environment

• Manufacturing plants
• Machine shops
• Aerospace facilities
• Automotive production facilities
• Medical device manufacturing companies

Sample Resume Job Description Bullet Points

• Programmed and optimized CNC mills and lathes to manufacture precision components within ±0.001-inch tolerances.
• Reduced cycle times by 15% through tooling and program optimization.
• Developed CNC programs from CAD models using CAM software.
• Conducted program verification and first-article inspections to ensure quality standards were met.
• Collaborated with engineering and production teams to improve manufacturing efficiency.
