Investigating Plasma-Nozzle Wear Based on Processing Time and Current Ampere

Abstract:

Plasma cutting machine widely uses in electrical conductivity industrial according to an accuracy dimension and minimum time consuming. A cutting surface and kerf are keys process parameter to establish process quality by controlling diameter of nozzle and size of electrode. Since kerf shape is crated base on nozzle diameter, while electrode is served plasma arc. This paper presents an investigating nozzle wear based on current ampere and processing time. The controlled variables are a plasma-cutting machine, Hypertherm powermax 45 xp, Bindee control CNC machine and cutting path as whorl specimen of low carbon steel. The current Ampere was handled at 35, 40, 45 A. The processing time was controlled at 1, 2, 3, 4, 5 minutes. The diameters of nozzle were measured using digital microscope. The experiments conducted based on ANOVA to establish the relationship of those parameters. The nozzle wear depended upon the current Ampere and processing time in which a regression equation was presented as a result.
