Abstract


The tap geometry plays an important role in the tool’s durability, influencing the forces during the tapping process and the way the chips are evacuated. This paper presents the geometry of a cutting tap that helps extend the cutting tool's life by reducing chipping, in C45 steel processing. The article contains details about: the geometry of the tap, the surface of the thread, the form of the chips, the forces that appear during machining and results obtained in this research. Based on the results, the objectives of this paper were achieved. The tap durability and the thread quality were improved, with the chip deposition on the rake surface reduced compared to the standard tap geometry.
