The results of the
experimental research of plasma cutting process were presented in this paper.
The impact analysis of the input process parameters: cutting current (I),
cutting speed (v) and material thickness (s), on the output process parameters:
kerf (sr), surface roughness (RZ) and bevel angle ({3) was done. The plasma
cutting machine (CNC) - type HPm Steel Max 6.25 was used in combination with
the plasma cutting unit - type Hypertherm HPR130. The workpiece material was
stainless steel X10CrNiMn-16-10-2 (EN 10025). Large numbers of cuts were made
using the differ- ent machine and plasma cutting unit settings. After process
data collection, its analysis was done by the software application MatLab. The
results were presented in tables as well as on diagrams, showing particularly
dependencies between input and output parameters under various conditions. The
objective of this paper was to visualize the influence of input parameters on
the output parameters, and to prepare the data for plasma cutting process
modelling, using different methods: statistical and artificial intelligence.
This paper was done
in the scope of the projects: TR35034 "The research of modern
non-conventional technologies application in manufacturing companies with the
aim of increase efficiency of use, product quality, reduce of costs and save
energy and materials", and TR33040 " Revitalization of existing and
designing of new micro and small hydro power plants (from 100 to 1.000 KW) at
the territory of south and south-east Serbia", funded by the Ministry of
Education and Science, Republic of Serbia.
