Greatly improved finishing and roughing performance
HEGGEMANN AG, based in Büren, is a service provider in the metalworking sector specialising in lightweight construction materials.
The performance package hyperMILL® MAXX Machining offers three modules for roughing, finishing and drilling that make it possible to achieve impressive boosts in productivity. HEGGEMANN AG, headquartered in Büren, Germany, is a development and manufacturing partner of the aerospace and automotive industry. The company uses hyperMILL® to reduce machining times by up to one third on a range of workpieces.
To ensure it is possible to meet the high requirements of a customer industry known for being challenging, HEGGEMANN employs highly qualified staff, both in its engineering and manufacturing operations. Employees define the most efficient manufacturing concept at an early stage during component development and construction. The engineering specialists have broad expertise covering a wide range of materials and production methods, and this is where their skills come into play. What’s more, the company is well equipped with machinery for working with sheet metal and solids. There is a total of 18 milling, turning and hybrid machines available for machining, with most coming from DMG Mori and Hermle. This puts HEGGEMANN in a position to be able to respond to all requirements in terms of complexity and volumes.
HEGGEMANN AG is also state of the art in terms of the software the company uses. 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. The ‘5-axis tangent plane machining’ strategy in particular has left a lasting impression at HEGGEMANN, as it offers enormous potential for savings, confirms René Reiffer, Head of Production at HEGGEMANN AG.
”Thanks to the 5-axis tangent plane machining strategy, we were able to reduce the machining time from 90 minutes to 15 minutes.“

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 new 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.
