Correct option is C
Sheet metal operations involve cutting, bending, and forming thin metal sheets. The commonly used tools include:
· Snips → Used for manual cutting of thin metal sheets.
· Power Shears → Used for machine-based cutting of sheet metal.
· Mallet → Used for bending and shaping sheet metal without damaging the surface.
Milling cutters are used in machining operations, primarily in milling machines for removing material from solid workpieces.
Milling is NOT a sheet metal process, as it is meant for bulk material removal rather than thin sheet forming.
