HEGGEMANN AG | Büren (North Rhine-Westphalia), Germany

HEGGEMANN AG, based in Büren, is a service provider in the metalworking sector specialising in lightweight construction materials.

HEGGEMANN has used the hyperMILL® CAM system from OPEN MIND since 2009. It particularly stands out thanks to the innovative hyperMILL® MAXX Machining performance package. hyperMILL® MAXX Machining offers three modules for roughing, finishing and drilling that make it possible to achieve impressive boosts in productivity. The company could reduce machining times by up to one third on a range of workpieces.

“Thanks to the 5-axis tangent plane machining strategy, we were able to reduce the machining time from 90 minutes to 15 minutes.”

René Reiffer, Head of Production at HEGGEMANN AG

Enormous line increments during finishing

A major component of the innovative finishing strategy is the tool it employs – a conical barrel cutter spe­ci­al­ly developed by OPEN MIND for this purpose. Its geometry has a large radius of 1,000 millimetres or more, allowing enormous line increments during finishing.
Reiffer’s team saves additional time when it comes to programming. It takes about 20 minutes to create a finishing programme for a pocket like this with a ball mill. It is possible to program machining jobs for the 5‑axis tangent plane machining in five minutes.

Optimised roughing for 2.5D, 3D or 5‑axis operations

The OPEN MIND performance package also offers other interesting high-performance cutting (HPC) strategies for roughing. For example, the hyperMILL® MAXX Machining roughing module allows the user to achieve a maximum stock removal rate by intelligently separating spiral and trochoidal-like tool paths and dynamically adjusting the feed rate to suit the prevailing cutting conditions. What makes this special is that it can be used for any type of machining operation, be it 2.5D, 3D or 5‑axis.
