Drilling is a precision machining process where a rotating drill bit is used
to create accurate, round holes in solid materials. This technique is widely
employed in manufacturing for fastener placement and structural support.
Turning is performed on a lathe where the workpiece rotates while a
stationary cutting tool removes material. It's primarily used to create
cylindrical or conical shapes with high accuracy and smooth surface
finishes.
Milling involves using a rotating multi-point cutting tool to remove
material from a stationary workpiece. It allows for precise shaping,
slotting, and cutting of complex parts in various directions and geometries.
End milling is a type of milling where the cutting tool's end and sides
remove material. It is ideal for producing slots, contours, and pockets with
high precision, commonly used in die-making and metal fabrication.
