Which operation would you perform to create a textured grip on a cylindrical surface?

• A. Knurling operation
• B. Turning
• C. Milling
• D. Grooving

Answer: (A)

Texture on a cylindrical surface is created by knurling. Knurling uses hardened rollers with raised teeth that press into the rotating outside diameter of the workpiece, forming a patterned texture such as diamond or straight lines. This texture provides a gripping surface, making it easier to hold the part, especially when hands are wet or oily. The process is typically done on a lathe while the part spins and the knurling wheels press the pattern into the surface with a controlled feed, leaving a consistent, uniform grip pattern along the cylinder. Turning shapes or finishes the outside diameter but doesn’t add a ridged pattern. Milling uses a rotating cutter to remove material and is more about creating flats, pockets, or complex features, not a circumferential grip texture on a small cylindrical portion. Grooving cuts a groove into the surface for channels or separations, not for a textured grip.
