The objective of this work is the investigation of milling process variables which resulting in optimal values of the surface roughness and material removal rate during machining of 7024 Al-alloy. The machining operation implemented on C-TEK CNC milling machine. The effects of the selected parameters on the chosen characteristics have been accomplished using Taguchi’s parameter design approach; also ANOVA had been used to evaluate the contribution of each parameter on the process outputs. Different feed rates are used ranging from (60, 80 and 100) mm/min, found that high feed rates gives a high material removal rates and good surface roughness. On the other hand, using three levels of spindle speeds found that a higher spindle speeds gives better surface roughness with a little effect on MRR. The process results showed that maximum MRR achieved (2.40) mm3/min when machining feed rate (100) mm/min, spindle speed (1000) r.p.m, and depth of cut (0.6) mm while good surface roughness (0.41 µm) when machining feed rate (100) mm/min, spindle speed (1000) r.p.m, and depth of cut (0.2) mm. The level of importance of the machining parameters for material removal rate and surface roughness and is determined by using Taguchi designing experiments and the variance analysis (ANOVA).

Desde la aparición de la figura de la willful blindness en Inglaterra, este complejo modelo de imputación subjetiva ha sufrido importantes cambios. En esencia, dicha figura permite calificar como dolosas actuaciones en las que el sujeto no conoció ni dominó los elementos del tipo, pero porque previamente había decidido no conocerlos cuando aún le era posible hacerlo. En este sentido, el presente artículo analiza la posibilidad de utilizar la willful blindness en los cuatro delitos que son de la competencia de la Corte Penal Internacional (genocidio, agresión, crímenes tanto de guerra como de lesa humanidad) y la utilización que ha tenido esta figura en el delito de lesa humanidad (por ser el único delito donde explícitamente se ha usado) por parte de los tribunales penales internacionales que precedieron a la Corte. Finalmente se presentan algunas conclusiones, así como una serie de recomendaciones de tratamiento jurídico que permitan castigar y sancionar a las personas responsables de infracciones internacionales mediante la willful blindness. A fin de conseguirlo se establecen los límites y pautas de interpretación, para que la figura no arroje más sombras que luces en la resolución de problemas judiciales.
