To this end, the rib milling knowledge management employee group developed a test part that featured all of the known degrees of difficulty, such as nesting, deep cavities, rib intersections, radial ribs and interference contours.
Based on this specification, OPEN MIND subsequently developed a rib milling cycle that introduces a lot of innovations to the machining sequence, such as: an integrated roughing/finishing function, integrated pocket machining of wide ribs, automatic collision detection of the tool holder taking conical milling tools into account and integrated bottom machining. Many of those involved see the fact that the infeed parameters always come directly from the tool database, even in the case of automatically separated areas, as a particular highlight.
In the case of components with a very high degree of ribbing, the new approach made it possible to significantly reduce processing times at the machine. The new rib milling cycle cut pure programming time in half. “In addition to the planned reductions in programming and machining times, we were also able to achieve greater process reliability and considerably reduce tool wear,” says Wolfgang Sofftner, contact partner for 3D machining in component tool engineering.
