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 Correct Answer Knurling

Explanation:

Knurling: Knurling is a process of impressing a diamond shape pattern on the surface of a workpiece to provide a better gripping surface.

Knurling is the operation of producing straight-lined, diamond-shaped patterns or cross lined patterns on a cylindrical external surface by pressing a tool called knurling tool. Knurling is not a cutting operation but it is a forming operation.
