Tapping in machining specifically refers to the process of creating internal threads in a workpiece. This is achieved by using a tool known as a tap, which has cutting edges designed to carve out the thread's profile as it is rotated and fed into a pre-drilled hole. The result is a threaded hole that allows for the insertion of screws or bolts, enabling effective mechanical fastening within components.

Understanding the significance of tapping is crucial since it is a fundamental aspect of fabrication and assembly in many mechanical applications. When designing components that require assembly with threaded fasteners, knowledge of the correct tapping technique and tap selection is essential for ensuring fit and function.

The other processes mentioned relate to different machining activities unrelated to tapping. For instance, creating external threads involves different cutting techniques and tools, polishing surfaces pertains to finishing operations to achieve smooth finishes, and cutting irregular shapes involves methods such as CNC machining or milling rather than tapping.
