“…Aluminium is very sensitive to heat input and application of thermal manufacturing technologies such as plasma jet cutting. Due to that, in previous experimental works authors conducted investigation of the influence of variable process parameters on the heat affected zone and material structure [ 29 ]. Based on the obtained results, it was concluded that significant structural changes in the heat affected zone did not occur.…”

“…Significant structural changes are expected to occur during plasma jet cutting and especially welding process of the heat treatable alloys. In the heat-affected zone of these alloys, heat treatment effects would be undone, for the reason of the intermetallic compound precipitates grain size going larger, which would eventually lead to hardness and material strength values decrease [ 29 ]. Workpiece sheet thickness is 3 mm.…”

“…En un estudio realizado anteriormente acerca de las propiedades de la superficie del acero después de ser sometida a un proceso de corte, se establece que: en el corte de metal, la profundidad de corte, la velocidad de avance y la velocidad de corte son los principales parámetros de control [8]. Hay una estrecha relación entre el material cortado, la herramienta de corte y las fuerzas de corte y calidad de la superficie cortada [9], [10], [11], [12], [13], [14], [15], [16], [17]. Así mismo, existen muchos estudios sobre esta relación entre los parámetros de corte y la calidad del producto final [14], [15], [16], y en la gran mayoría se llega a la misma conclusión, así como lo afirman Muñoz y Cassier [7], en su estudio realizado en 1998 el cual se centran en la influencia de la velocidad de corte sobre el acabado de la superficie afirman lo siguiente: "las variables tales como la velocidad de avance, el radio de corte y la velocidad de corte pueden proporcionar un control de la calidad y el acabado de la superficie en un proceso de mecanizado determinado".…”

“…El acero ASTM A-36 es un acero de bajo carbono, es ampliamente utilizado en la fabricación de estructuras, puentes viales e infraestructura petrolera [10]. El material será sometido a procesos de corte convencionales (fresado, sierra, oxicorte) y algunos procesos no convencionales (rayo láser, rayo de plasma) [11], [12], [13]. Se analizarán las propiedades de la superficie cortada tales como rugosidad, dureza y microestructura, para cuantificar los cambios que se presentan en el material dependiendo del método de corte usado.…”

“…Verified model was used to generate 2D and 3D plots that show effects of process parameters on kerf width values and to define cutting areas that result with minimal kerf widths. Peko et al [12] conducted research of the heat affected zone occurred in material during plasma jet cutting process. Heat affected zone analysis was done by measuring hardness changes on the material cross sections and by microscopic observations of the material structure.…”
