Abstract

El objetivo de este trabajo consistió en la aplicación de un método óptico interferométrico para la evaluación del desgaste en una pastilla de metal duro. Se describe el esquema experimental para la aplicación de la técnica de la Holografía Digital utilizada para el registro de los hologramas digitales en una cámara CCD (Dispositivo de Carga Acoplada). La pastilla inspeccionada con la técnica óptica fue previamente montada en una estructura de soporte y ligeramente calentada con una lámpara de halógeno para evidenciar las regiones con defecto o desgaste. Para el procesamiento de las imágenes, se utilizó el software, ProITec. Fue posible detectar, con alta resolución y sin contacto, los defectos que puedan comprometer la integridad estructural de la pastilla analizada, ningún defecto fue encontrado. Del análisis de las imágenes obtenidas, se verifica que la pastilla se deforma como un todo, sin que presente cualquier alteración visible en su patrón de franjas.

Palabras claves: holografía digital, pastillas de metal duro, interferometría holográfica, unwrapping.

Abstract

The objective of this work is the application of an interferometric method for validating the result of wear in a cutting tool insert of hard metal. We describe in this paper the experimental setup for the application of Digital Holography technique, used with digital recording of holograms on a CCD camera. The cutting insert inspected with the optical technique was previously mounted on a support structure and slightly heated with a halogen lamp for evidence of defective regions. For image processing, the software used, ProITec. It was possible to detect, with high resolution and contactless defects that could compromise the structural integrity of the insert analyzed, no defect was found. Analysis of the images obtained, it is verified that the object is deformed as a whole, not to present any visible alteration in their pattern of fringes.

Key words: digital holography, hard metal chip, holographic interferometry, unwrapping.
