Sheet-metal operations — term for longitudinal straight cutting What is the correct name for the operation in which a sheet or strip is cut in a straight line along its length to produce narrower strips?

Introduction / Context:Press-shop terminology distinguishes between different shearing and forming actions. Using the right term helps avoid ambiguity in process planning and tooling design.

Given Data / Assumptions:

• Straight, longitudinal cut along the length of a coil or sheet.
• Objective is to divide a wide strip into multiple narrow strips.
• No deliberate bending or forming during the cut.

Concept / Approach:“Slitting” is the longitudinal shearing of sheet or strip to reduce width. It is done on a slitting line or with rotary slitter knives. This differs from “notching” (removing a piece from an edge), “lancing” (partial cut followed by a bend), “plunging” (non-standard term in this context), and “forming” (plastic deformation without material removal).

Step-by-Step Solution:Identify action: straight cut along length.Map action to standard term: slitting.Select “slitting”.

Verification / Alternative check:Coil processing lines are commonly called “slitting lines”, confirming the accepted terminology.

Why Other Options Are Wrong:

• Notching: local removal at an edge or corner.
• Lancing: partial cut plus bend to form tabs/louvers.
• Forming: changes shape without cutting.
• Plunging: not a standard press term for longitudinal shearing.

Common Pitfalls:Confusing slitting with “shearing” generally; shearing is the broader category, while slitting is specifically longitudinal.

Final Answer:slitting
