Tapping is an extensively employed manufacturing process by which a multi-teethtool, known as a tap, cuts a mating thread when driven into a hole. When taps are new orslightly worn, the process is under control and the geometry of the resulting threads on theworkpiece is correct. But as the tap wear increases, the thread geometry deviates progressivelyfrom the correct one and eventually the screw threads become unacceptable. The aim ofthis paper is to outline the development of a statistical process control strategy for decisionmaking based on data coming from the current signal of the tap spindle for assessing threadquality. It could operate on line, and indicates when the tap wear is so critical that, if theprocess were continued, it would result in unacceptable screw threads. The system would bevery cost-effective since the tapping process could be run without any operator intervention.(original abstract)
