ABSTRACT
A study on the machining characterist-
ics using plasma assisted machining of AISI 1045 steel and Inconel 718
Hard materials such as titanium, Inconel and nickel alloys are mostly used
in aerospace. Automobiles and medical devices. These materials are
difficult to machine with conventional machining (CM) methods. Learning
new machining methods developed for these materials. One of these
machining methods, Thermal Assisted Machining (TAM,) is applicable. A
heat source for increasing the machinability of materials. Laser assisted
milling (LAMill) is a widely used type of Thermal Assisted Machining. In the
Laser assisted milling process, a laser heat source softens the material in
front of the cutting tool. Even though, Laser assisted milling is expensive.
Plasma heat source is widely used for welding, melting, preheating etc.
One-tenth the cost of a laser heat source. But few studies have been done
on plasma assisted machining (PAM). Conducted in this study, a PAM
process was developed, investigated and its performance was compared
with Laser assisted milling and conventional machining. The correct
preheating temperature and depth of cut (DOC) were determined
thermally Analysis. Experiments were performed using the PAM system
on used AISI 1045 steel and Inconel 718. The results of the experiments
showed that PAM and LAMill produced excellent effects with respect to
tool life and the machined material surface. However, the cost of the
plasma heat source is much lower than that of LAMill, so PAM can be
considered a more efficient TAM method.
