El conocimiento de las desviaciones generadas respecto de la geometría final de la pieza permite desarrollar módulos de corrección en el propio software, basados en las diferentes estrategias de mecanizado, posibilitando así que el ejecutor genere las oportunas correcciones antes de la fabricación, de manera que los productos acabados se encuentren dentro de las especificaciones de diseño. Al mismo tiempo, se ha estudiado el trabajo SIM en los procesos de fabricación mediante la aplicación de redes neuronales artificiales (ANN) como solución a los problemas no lineales y parámetros conflictivos. Por lo tanto, este documento evalúa la influencia de la geometría y el acabado superficial de tres estrategias diferentes de fresado, sugeridas por un software de CAM en la fabricación de un producto, por medio de RNA.
3D measurement of human plantar foot by projection moiré technique

Four digital phase shifted parallel grating patterns are projected upon the specimen surface and observed by the camera. A phase map of moiré fringes is produce digitally combining the fringe maps distorted by the foot whit those, left undistorted, by a reference plane. The 3D profile was calculated using two-dimensional greyscale images by dedicated software. This profile was compared to the measurement data of the same foot obtained from a coordinate measuring machine (CMM). A brief metrological analysis estimated an uncertainty value of 6.3% for the foot. The main advantages of this system were its easy set-up, use of standard optical components, absence of moving parts and its possible applicability in bioengineering.

This paper investigates the use of Taguchi's method in order to identify the best drilling setup of glass reinforced polyamide. Experimental study on PA6 and PA66GF30 composites was conducted using three carbide drills (K20) with different geometries. The effect of tool geometry, spindle speed and feed rate factors on the thrust force, hole mean diameter and circularity error were analyzed. The results revealed the quality of the holes can be improved by proper selection of cutting parameters.

This work describes novel sisal fibre reinforced aluminium laminates (SiRALs) that have been prepared by cold pressing techniques and tested under tensile, flexural and impact loading. The pristine sisal fabric and the sisal fibre reinforced composites (SFRCs) were also tested to understand the difference in mechanical performance of the sisal fibre metal laminates. The SiRALs achieved not only the highest modulus and strength, but also the highest specific properties. The mean specific tensile strength and modulus of the SIRALs reached increases of 132% and 267%, respectively, when compared to the sisal fibre reinforced composites (SFRCs). Moreover, the mean specific flexural strength and modulus of the SiRALs were significantly higher than SFRCs, revealing increases of 430% and 973%, respectively. A delamination fracture mode was noted for SiRALs under bending testing. The SiRALs can be considered promising and sustainable composite materials for structural and multifunctional applications.
