Selecting and installing cutting tools.
Setting workholding, chucks, fixtures and jaws.
Establishing machine datums using probing equipment or dial indicators.
Select, load and prove CNC programs.
Read and interpret engineering drawings and technical specifications.
Edit CNC programs and make appropriate offset and setting adjustments to maintain component dimensions and quality.
Adjust tooling, speeds, feeds and offsets to optimise machine performance and cycle times.
Carry out first-off inspections and ongoing in-process inspection.
Use precision measuring equipment including micrometers, verniers/calipers and shadow graphs to ensure components meet drawing requirements and tight tolerances.
Monitor machines during production and identify issues such as tool wear, machine malfunctions or out-of-tolerance components.
Undertake in-cycle deburring where required.
Record production output, scrap and quality information accurately.
Maintain tooling sheets and ensure CNC programs are kept up to date.
Identify alternative tooling solutions and put forward improvement ideas.
Complete works orders in line with the Kanban system.
Ensure any material, quality, tooling or production issues are reported promptly.
Ensure material, tooling and gauging are available before setting machines.
Carry out routine machine cleaning, checks and basic preventative maintenance in line with TPM requirements.
Maintain a clean, organised and safe working environment, including good 5S standards and correct use of PPE.
Participate in the High Performing Team (HPT) and contribute to problem-solving and continuous improvement activities.
Support other departments where required.
