This paper evaluates the dimensional stability (diameter, roundness and cylindricity) and surface roughness of reamed cylindrical holes using K10 cemented carbide welded blade reamers on aluminum-silicon hypoeutectic (SAE 322) cast alloy at various cutting conditions in order to optimize the cutting process.
It was realized that, to have the thixoforming process of these hypoeutectic alloys correctly applied, it is necessary to achieve a temperature where AlFCC coexists with the liquid rich-silicon; nevertheless, the semisolid behaviour will depend on the remaining solid's morphology and shape.
