In this paper we present a technological problem encountered in the machining accuracy of the parts for aerospace, made of aluminum alloy extruded profile with 7 meters length. Those parts have very tight tolerances and on milling process appears deviation due to thermal expansion effect, which influences the repeatability of machining processes. T...

The toroidal cutting edge, also called corner cutter, is a combination of the cylindrical-frontal milling cutter and the spherical head milling. The paper follows at generating the optimal trajectory for making the finished product with the toroidal cutting edge without having to use the flat end mill and the ball nose end mill. This trajectory is ...
