Plasma arc cutting is an economical
thermal machining process for nickel-based alloys
due to its versatility and efficiency. Machining of
these alloys is very expensive, therefore a precutting
analysis is required to find the best
parameter setting to achieve maximum material
removal with minimum surface roughness. A
series of experiments designed by means of Design
of Experiment (DoE) method have been conducted
to provide statistical data for plasma arc cutting
on nickel-based alloys. This paper describes the
use of Design Expert software to optimize the best
parameter setting for plasma arc cutting of nickelbased
alloys in order to achieve maximum material
removal rate (MRR) with minimum surface
roughness (Ra). The software uses Analysis of
Variance to analyze the results and response
surface method (RSM) to create 3D model graph
to find these values. The result shows that material
removal rate can be achieved at higher speed with
the quality of surface roughness better than the
nominal value.
