Tapping is a type of machining process used to create screw threads, which are helical ridges that wrap around the cylindrical or conical surfaces of a workpiece. During tapping, a tool called a tap is used to cut threads into a hole, while the workpiece rotates to create the desired thread pattern. Tapping can be performed manually or with the use of a tapping machine, and is commonly used in the manufacturing of products that require screw threads, such as bolts, screws, and nuts. The quality of the threads produced during tapping is dependent on factors such as the type of material being tapped, the size and pitch of the threads, and the speed and feed rate of the tap.
