A B S T R A C TThe characteristics of carbon fibre reinforced laminates had widened their use, from aerospace to domes-tic appliances. A common characteristic is the need of drilling for assembly purposes. It is known that a drilling process that reduces the drill thrust force can decrease the risk of delamination. In this work, delamination assessment methods based on radiographic data are compared and correlated with mechanical test results (bearing test).

“…Una es la acción de los filos principales de corte y la otra es la acción del bisel transversal. Los modelos propuestos por Shaw y Oxford fueron desarrollados para el mecanizado de metales, además han demostrado su aplicabilidad en materiales compuestos (Okutan et al, 2013;Fernandes y Cook, 2007). Karabay (karavay 2007) utilizó el modelo como base para desarrollar un sistema de medición para taladrado.…”

ResumenEn este artículo se presenta una forma corregida del modelo de Shaw y Oxford para brocas con geometría mejorada y ausencia de bisel transversal. Se ha realizado un ajuste de las expresiones que conforman el modelo y se han determinado los parámetros experimentales para estimar la fuerza de avance y el par de taladrado en aluminio Al-2011. Los resultados obtenidos mediante el modelo corregido se han comparado con valores estimados mediante el modelo de la presión específica de corte. Finalmente, se muestra que el modelo de Shaw y Oxford puede ser aplicado en brocas con geometría mejorada mediante el ajuste del parámetro asociado al bisel transversal. Palabras clave: presión específica de corte; mecanizado; fuerza de corte; taladrado; Shaw y Oxford The Shaw and Oxford Model Applied to a Process of Drilling that uses Twist Drills with Innovated Geometry and without Chisel AbstractThis article presents a corrected form of the Shaw and Oxford model for drills with improved geometry and absence of the edge chisel. Adjustments of the expressions that compose the model have been made, and also the experimental parameters have been determined in order to estimate the thrust force and the torque of the drilling in aluminum Al-2011. The results obtained through the corrected model, have been compared with estimated values through the specific cutting pressure model. Finally, it is proved that the Shaw and Oxford model can be applied to drills with improved geometry through the adjustment of the parameter associated to the edge chisel.
