Abstract (Spanish)
El corte de acrílico con láser de CO2 es un proceso muy utilizado dentro de la industria de la transformación de plástico debido a la excelente calidad del corte y a su precisión. En el mercado existen dos tipos de acrílico: el fabricado con metil-metacrilato virgen y el fabricado con metil-metacrilato reciclado. En este estudio se realizaron pruebas de corte láser de CO2 de estos dos materiales, con distintos parámetros de velocidad y potencia, para observar cuánto se afectan estos materiales por el calor generado durante el proceso de corte y qué diferencias hay en la calidad de corte. Los resultados experimentales mostraron que el comportamiento durante el corte láser del acrílico virgen y el acrílico reciclado es muy distinto debido a las impurezas propias del acrílico reciclado.
Abstract (English)
Cutting acrylic with CO2 laser is a widely used process in the industry of plastic transformation due to the excellent quality of the cut and its accuaracy. In the plastic maker there are two types of acrylic, one manufactured with virgin methyl-methacrylate nad the other manufactured with recycled methyl-methacrylate. In this study, cutting tests of these two materials were made with a CO2 laser using different parameters of speed and power in order to observe how both materials are affected by the heat generated during the cutting process and if there were any differences on the cutting quality. The experimental results showed a great difference in behavior between the virgin acrylic and recycled acrylic during laser cutting, due to the impurities in the recycled acrylic.
