NC programmer Günter Fasching gives an example of how his work has got faster: “In the past, I developed a 5-axis NC program for a toothing stamp; I had to wait for about one and a half hours for the milling paths to be calculated. With hyperMILL®, the paths are calculated in about five minutes.”
The CAM team in Denklingen has also been able to reduce programming times by using the 5-axis-optimised rest material roughing function. A further advantage of indexed 5-axis machining is that shorter tools can be used. This guarantees greater stability and performance. This strategy also allows hard-to-reach areas and cavities to be machined particularly efficiently.
According to NC programmer Thomas Karg, it was necessary in the past, when programming rest material roughing, to work forward manually, tilt angle by tilt angle while watching out for various restrictions. Now, if you choose the ‘Indexing’ function, you can define the tilt angles for the B and C axes easily and quickly using two methods. The ‘Planes’ option allows you generate the tilt angle from the plane normal. In ‘3D mode’, the tilt angles are created automatically within a defined range of angles. All connecting paths between the tilt angles are optimised and fully checked for collisions.
Roughing during electrode manufacturing is also drastically accelerated. The Hirschvogel tool makers estimate that an average time saving of between 10 and 20 per cent can be achieved with the high-performance cutting strategies of the hyperMILL® MAXX Machining package. The machining strategy increases the speed and tool life. Stress on the tool and machine is reduced at the same time.
