millyuGO, GO2cam’s Adaptive Roughing Cycle millyuGO, patented in 2016, is a technological breakthrough in the field of adaptive toolpaths. With millyuGO, the tool remains on the part as much as possible and the toolpath automatically switches from spiral to trochoidal tool movements when the geometry of the part requires it. This toolpath prevents sharp angles, full cuts and abrupt changes in direction so that the tool can keep an average speed close to the programmed feedrate. millyuGO generates toolpaths with constant tool engagement during the whole roughing cycle. This induces constant velocity and no vibrations, enabling hard materials machining, like titanium, inconel or stainless steel, without breaking the tool and the spindle. The results show that tools last 6 times longer and machining time is reduced up to 80%. Production gains are above 50%.
