Tapping in sheet metal cutting refers to the process of creating internal threads in a metal workpiece. This is commonly done to facilitate the attachment of screws, bolts, or other fasteners. Tapping involves cutting threads into a pre-drilled hole using a specialized tool called a tap. The tap typically has flutes or grooves along its length that help remove material as it cuts, creating the threaded pattern.
In sheet metal cutting, tapping is often required when assembling metal parts that need to be securely fastened together. This could include applications in industries such as automotive manufacturing, aerospace, construction, and electronics.
