Por medio de modelos experimentales y geométricos, y en un entorno simulado, se determinan valores de rugosidad propia de desviaciones de tercer orden. El entorno de simulación se desarrollada a partir de la integración y verificación simulada (ISV) en software CAD/CAM NX 11. Las aproximaciones geométricas son validadas por medio del análisis de las nubes de puntos. Se realizan dos diseños de experimentos para determinar la influencia de los factores geométricos dinámicos, definidos como avance transversal (Ae), ángulo lead y ángulo tilt, con una herramienta de fresado de punta plana. Un experimento 2 se desarrolla con propósitos de ubicar una zona de influencia de los parámetros mencionados y validar la precisión del entorno simulado. Para el segundo experimento se presenta un modelo factorial 3 , a fin de precisar el factor de mayor influencia sobre la rugosidad. Como resultado de la experimentación se obtiene un valor óptimo (mínimo) de rugosidad, ubicado en zonas en donde el avance transversal es determinante y de alto impacto, el ángulo lead tiene una influencia moderada y el ángulo tilt es el factor de menor influencia. Los valores mínimos de rugosidad se presentan cuando el avance transversal es bajo, el ángulo lead es bajo y el ángulo tilt es alto. El método presentado pretende ahondar en el maquinado para terminado de superficies libres con herramienta de punta plana.

“…The experimental characterization of the surface topography generated with a ball end mill is proposed by several authors. Zhang et al [21], Han and Zhao [22] and Chen et al [23] studied the effect of milling with a two teeth tool on amplitude roughness parameters. All studies are carried out with a constant spindle rotation speed but several tool inclinations, which involve a variation of the cutting speed.…”

Five-axis milling with a ball-end cutter is commonly used to generate a good surface finish on complex parts, such as blades or impellers made of titanium alloy. The five-axis milling cutting process is not straight forward; local cutting conditions depend a lot on the geometrical configuration relating to lead and tilt angles. Furthermore, the surface quality is greatly affected by the cutting conditions that define the milling configuration. This study presents a geometrical model of five-axis milling in order to determine the effective cutting conditions, the milling mode, and the cutter location point. Subsequently, an analysis of surface topography is proposed by using the geometrical model, local criteria, and a principle component analysis of experimental data. The results show the effects of local parameters on the surface roughness, in relation to the lead and tilt angles.

Sculptured surfaces have been widely used in various engineering applications. With the development of five-axis machining technology, five-axis machine tool has played a more and more important role in manufacturing sculptured surfaces. This article proposed a complete five-axis machining process planning for vehicle rear bumper mold. First, a numerical model considering tool inclination was developed to predict topography and surface roughness in ball-end milling processes. And then experimental verification was conducted. Second, according to the simulation results, it can be concluded that surface roughness decreases significantly with the tilt angle increasing from 0°to 5°. When the tilt angle is 10°, surface roughness gets the smallest value. What is more, surface roughness increases slightly from 10°to 30°. In the case of the permitted surface roughness, larger feed rate per tooth and the radial cutting depth can be chosen. Finally, a process strategy was made through the analysis of the mold in which the parameters were chosen according to the simulation results above.
