Level 3 – Machining Technician
Occupational Role Profile
The manufacturing industry offers a dynamic and rewarding career both in the UK and internationally, providing a wide range of opportunities for individuals to work in technically advanced and innovative environments.
Organisations within this sector vary from small, family-run businesses to large multinational corporations, all contributing to the country’s economic growth and technological advancements. The UK’s manufacturing industry is globally recognised for its innovation and excellence, necessitating a high degree of skill and knowledge across all levels.
A Machining Technician is a key role in precision engineering, responsible for setting up, operating, and adjusting machine tools to produce high-quality components that meet strict industry standards. These components may be used in industries such as aerospace, automotive, energy, and medical engineering, where accuracy and quality are essential.
Machining Technicians will work with a variety of materials, including metals, composites, and polymers, using manual and computer numerical control (CNC) machinery. They must understand and interpret engineering drawings, select the appropriate tools and machining techniques, and apply quality control processes to ensure that components meet precise specifications.
They will also be required to adhere to strict health and safety regulations, maintain an organised and efficient workspace (e.g. 5S principles), and contribute to continuous improvement activities within their organisation. Additionally, they will need to work collaboratively with colleagues, supervisors, and quality control teams to troubleshoot issues and optimise production efficiency.
Core Knowledge
A Machining Technician will develop knowledge and understanding of:
- Health & Safety: Statutory and organisational regulations relating to machining operations, including safe working practices.
- Environmental Compliance: Procedures and systems for minimising environmental impact, such as ISO 14001.
- Engineering Drawings & Specifications: How to read, interpret, and apply technical drawings, CAD models, and work instructions to produce accurate components.
- Materials & Tooling: Properties of different materials (metals, composites, plastics) and how to select the appropriate cutting tools, speeds, and feeds for machining operations.
- Machining Processes: Principles of manual and CNC machining, including turning, milling, grinding, and drilling.
- Quality Assurance: Inspection techniques and compliance with quality standards such as ISO 9001, including first-off and in-process inspection methods.
- Problem Solving: Identifying machining issues, diagnosing faults, and implementing corrective actions using problem-solving techniques.
- Continuous Improvement: Lean manufacturing principles such as Kaizen and 6S, aiming to improve quality, efficiency, and safety.
- Communication: Effectively conveying technical information using various communication methods, including written reports, verbal discussions, and digital systems.
- Workplace Organisation: Maintaining a clean, safe, and structured work environment through 5S and other best practices.
Core Skills
A Machining Technician will develop the ability to:
- Health & Safety: Work safely at all times, adhering to regulations, using appropriate Personal Protective Equipment (PPE), and identifying potential risks.
- Environmental Compliance: Follow procedures to reduce waste, recycle materials, and comply with environmental regulations.
- Engineering Drawings & Specifications: Accurately interpret engineering documentation to machine components to precise specifications.
- Material Selection & Tooling: Choose the correct materials, cutting tools, and machining parameters based on engineering requirements.
- Machine Setup & Operation: Set up and operate manual and CNC machines, ensuring precision and adherence to standard operating procedures.
- Quality Assurance: Perform quality checks using measuring instruments such as vernier calipers, micrometers, coordinate measuring machines (CMM), and gauges.
- Problem Solving: Identify and resolve machining errors, tool wear, or quality defects, escalating issues as required.
- Continuous Improvement: Contribute to lean manufacturing initiatives, process optimisation, and workplace efficiency improvements.
- Communication: Clearly and accurately record and relay information regarding machining operations and issues.
- Workplace Organisation: Ensure an organised and efficient work environment, following workplace organisation techniques.
