Will AI replace Grinding, Lapping, Polishing, and Buffing Machine Tool Setters, Operators, and Tenders, Metal and Plastic?

What this score means

Grinding, Lapping, Polishing, and Buffing Machine Tool Setters, Operators, and Tenders, Metal and Plastic is among the least exposed roles in Manufacturing. Most of what the job involves still sits outside what current AI can do, even as the tools around it keep changing. At 11 out of 100 it scores 3 points below the Manufacturing average of 14. Across the 3 sources behind this baseline, individual estimates run from 5 to 20, so the score is a weighted consensus rather than any single figure.

The number is a consensus estimate for the typical version of the role, built from published academic and industry research scored occupation by occupation. It is not a prediction about any individual. How scoring works

What this job actually involves

Exposure follows the work itself rather than the job title, so it is worth seeing what the role is made of. These are the tasks O*NET records for Grinding, Lapping, Polishing, and Buffing Machine Tool Setters, Operators, and Tenders, Metal and Plastic, most central first, showing 12 of 18.
