A Study of Cutting and Forming Threads with Coated HSS Taps
Original language description
Tapping is a very common machining process for producing internal threads. A tap is a cylindrical or tapered thread cutting tool having threads of a desired form on the periphery. Combining rotary motion with axial motion, a tap cuts or forms the internal thread. Due to desired accuracy and versatility of thread profiles most taps are made of high speed steel. Physical surface coating taps (monolayer, duplex or triplex) increases tap life and improves thread finish. Regarding the CNC canned cycles the demands on safe tool performance of the threads are more and more urgent. This paper deals with a study of 2D surface parameters, Coulomb´s coefficient of friction, energy consumption and cutting/forming performance of selected PVD coated HSS taps when machining of carbon steel C45 and forming of hardened steel 42CrMo4V.
