The cold forming process in which a hardened tool is pressed against a workpiece (when there is relative motion between the tool and the workpiece) to produce a roughened surface with a regular pattern is

1. Roll forming
2. Strip rolling
3. Knurling
4. Chamfering

Correct answer: Knurling

Solution

Knurling is a cold forming process that creates a textured pattern on a workpiece by pressing a hardened tool against it while both are in relative motion, resulting in a roughened surface that enhances grip.
