Abstract
The internal threading with tap or forming tap, is a widely applied factoring process throughout industry. However, the knowledge held by the toolmakers is not transferred to the scientific literature, which justifies the small number of studies regarding this matter. This data limitation reduces the tool and cutting condition selection guide to geometrical characteristics. This current work has two main goals; the first one is to study the process behavior regarding the secondary and uncontrollable characteristics, such as thread length, tool coating, feed rate, and hole’s diameter. It also investigated the load distribution in the cutting edge for a tap operation. The second goal of this work is the investigation of the behavior of a new type of floating system in terms of torque and axial force. One of the outcomes of this work was that the torque distribution along the fillet was not uniform, with the torque of the third fillet higher than the others. The floating system tested reduces the axial force and torque by reducing synchronicity errors even in extremely conditions.
