Quality control on the shop floor is a direct responsibility of every supervisor.
Even though we have a dedicated Quality Control department, the supervisor’s role in maintaining standards is fundamental. Why? Because the first level of quality must be ensured right at the workstation, during and immediately after machining.
Here are some methods and algorithms I follow when checking parts:
- Visual inspection – detect any obvious surface defects, burrs, scratches, or tool marks.
- Dimensional verification – using micrometers, callipers, gauges, or height measuring systems (like Trimos), ensuring parts meet tolerance before they leave the machine.
- First off approval – carefully checking the very first component of a batch and aligning it with the drawing, program, and setup sheet.
- In process monitoring – periodically measuring workpieces during the run to identify tool wear or thermal drift before they affect the batch.
- Random batch checks – selecting parts from production at random intervals to confirm continuous accuracy.
- Documentation – recording measurements and issues in logbooks or digital systems for traceability.
The QC department validates the final product, but the supervisor sets the tone for consistent quality on the shop floor. By doing this, we save time, reduce scrap, and build trust with both the team and the customer.
