An Experimental Study of Influence
of Process Parameters on Dross Height
Formation
Aniket Jadhav and Shailendra Kumar
Abstract This paper presents an experimental study on influence of process parameters of laser machining of AISI 304 material on dross height formation. Laser
power, cutting speed and gas pressure are process parameters which are considered
during present work. Design of experiments is implemented using response surface
methodology, and analysis of variance is carried out in order to find out significance
and influence of process parameters for dross properties. It is identified that cutting
speed acts as the most important significant parameter accompanied by laser power
and gas pressure. Dross height increases with the enhancement in cutting speed and
decreases with the reduction in laser power and gas pressure. Further, optimization
of process parameters is also carried out to reduce dross height formation. Based on
the experimental analysis, second-order mathematical model is formulated for the
prediction of dross height. Model predictions and experimental results are found in
reasonable agreement.

1 Introduction
AISI 304 is an austenitic stainless steel. It has wide range of applications including
architectural, nuclear, consumer, ships manufacturing, transportation firms, etc. [1].
Thick austenitic stainless steel is hard to cut sheet material and widely used in
production industries due to excellent mechanical properties. Cutting of this material
by using conventional machining process is difficult due to excessive friction, tool
