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.
