Milling operation identification The operation of producing circumferential grooves (narrow slots) around the periphery of a cylindrical or conical workpiece with a milling cutter is known as:

Introduction / Context:
Milling nomenclature distinguishes operations by cutter type and the feature produced. When narrow grooves or slots are required around the outside surface, a saw-type cutter is commonly employed.

Given Data / Assumptions:

• Grooves are relatively narrow and repeated around the periphery.
• Work may be cylindrical or conical.
• Straight slots rather than helical threads are intended.

Concept / Approach:
Saw milling uses a thin, disk-shaped milling cutter (plain or side-and-face) to generate slots and grooves. Helical milling is used for helical features like threads or flutes. Profile milling follows a complex outline, while gang milling uses multiple cutters simultaneously but does not, by itself, define the groove type.

Step-by-Step Solution:
Identify the feature: narrow grooves/slots around the periphery.Match to cutter: thin saw-type cutter for efficient slotting.Select operation name: saw milling.

Verification / Alternative check:
Shop practice commonly calls narrow circumferential slots “saw cuts,” produced by slitting saws or side-and-face cutters.

Why Other Options Are Wrong:
(a) Profile milling handles complex outlines, not simple grooves. (b) Gang milling is about multiple cutters at once, not specifically grooves. (d) Helical milling produces helical grooves (threads/flutes), not straight circumferential slots. (e) Form relieving is unrelated to slotting.

Common Pitfalls:
Confusing helical grooves with straight grooves; choosing gang milling simply because multiple grooves are required.

Final Answer:
Saw milling
