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 twomain 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.
