Job Description

A CNC Supervisor oversees the daily operations of the CNC department, ensuring the safe, efficient, and timely production of high-quality components. This role is a blend of hands-on technical expertise and leadership, with primary responsibility for developing, optimizing, and maintaining all CNC-related processes, including programming, tooling, and Workholding.

Key Responsibilities

• Supervision & Leadership:
  • Direct and coordinate the daily activities of the CNC team, assigning tasks and ensuring production targets and deadlines are met.
  • Mentor, train, and develop junior machinists and operators, fostering a culture of safety, quality, and continuous improvement.
  • Conduct performance reviews, provide constructive feedback, and address any personnel or production issues in a timely manner.
  • Enforce all safety protocols, company policies, and quality standards (e.g., ISO, GD&T) to maintain a safe and efficient work environment.
• CNC Programming & Process Optimization:
  • Develop and implement CNC programs for a variety of machines (mills, lathes, etc.) using CAM software (e.g., Mastercam, SolidWorks CAM).
  • Analyze engineering drawings, blueprints, and CAD models to determine the optimal machining methods, toolpaths, and cutting parameters.
  • Write and edit G-code programs, ensuring they are efficient, error-free, and produce parts that meet strict tolerance requirements.
  • Troubleshoot and resolve machining issues to minimize downtime and improve overall efficiency.
• Tooling & Fixture Design:
  • Select and manage the appropriate tooling for each job, including cutting tools, inserts, and tool holders, to optimize material removal rates and tool longevity.
  • Design and fabricate custom fixtures and workholding solutions to efficiently secure complex or unique parts during the machining process.
  • Manage and maintain the tool crib, ensuring accurate inventory and ordering of tooling and supplies as needed.
  • Collaborate with engineering and design teams to provide feedback on part manufacturability and suggest improvements to designs.

Qualifications & Skills

• Education & Experience:
• A technical degree in a related field or a Journeyman-level machinist certification is preferred.
• Minimum of 5-7 years of hands-on experience in CNC machining, with at least 2 years in a supervisory or leadership role.
• Proven experience in CNC programming, tooling setup, and fixture design.
• Technical Skills:
  • Proficiency in CAM software and solid modeling programs (e.g., SolidWorks, Fusion 360).
  • Expertise in reading and interpreting engineering drawings, including a strong understanding of Geometric Dimensioning and Tolerancing (GD&T).
  • In-depth knowledge of various CNC machine controls (e.g., Fanuc, Haas), machining processes (milling, turning), and material properties.
  • Skilled in using precision measurement tools such as calipers, micrometers, and CMMs.
• Soft Skills:
  • Excellent leadership, communication, and interpersonal skills.
  • Strong problem-solving and analytical abilities to identify root causes and implement corrective actions.
  • Highly organized, self-motivated, and capable of managing multiple priorities in a fast-paced environment.
