Wessling (Germany), 16 September 2013 – OPEN MIND Technologies AG, one of the leading CAD/CAM software developers, is releasing hyperMILL® 2013. The many improvements and extensions found in the new version of this popular CAM software solution provide even more efficient usage of modern NC machines and cutting tools. At the same time, the software further cuts down on programming time and extends tool life.
One of the highlights of hyperMILL® 2013 is its extension for ‘5axis contour offset finishing’: Barrel cutters can now be used here.. This strategy uses the large effective radius of the barrel cutter with a point milling contact style. The radius of the milling tool allows increased step-over distances between passes for free-form surfaces. The software’s new ‘Rib milling’ cycle was jointly developed by OPEN MIND and a leading German automotive manufacturer. This is good news for tool makers who need to mill deep, narrow cavities for ribs in their moulds. The cycle automatically detects grooves to be milled and steep areas and floors are machined separately. Depending on the workpiece geometry, the system selects a suitable roughing strategy, and contiguous areas are completely machined.
Modules for specialists
The connections between tool paths and depths have been smoothed for the roughing and floor machining of impellers and blisks, which is one of the special applications within hyperMILL®.The tire module, which is designed for the efficient machining of tire moulds, has also been improved. Specifically, OPEN MIND has developed a ‘Tire Browser’. The tire clock component of this browser contains all relevant tire design information (segment, tracks, pitch sequence, pitches).
Machine tools are becoming increasingly dynamic. Along with fast acceleration, this also results in a shock to the structures and even to the cutting tools. OPEN MIND is counteracting this with its improved strategies in hyperMILL® 2013. One example for softer movements that are easier on machines is ‘Extended contour compensation’. This new function analyses the tool paths for areas where sudden changes in direction may be encountered. As part of contour compensation, small transition radii are then inserted at critical contour changes. Movements have also been softened for 5axis drilling: It is now possible to use rounded infeeds in G1 with an increased feedrate for connection moves between drill holes. This makes the tool movements more constant and harmonious, while also reducing positioning times.
Another example of the CAM solution’s tool-saving strategies is a ‘Variable stepover’ for mill turning with ceramics inserts. Gradually ascending/descending infeed depths during roughing ensure that the full length of the inserts is made use of.
CAD for CAM users
CAD-integrated solutions are crucial for continuous workflows. Joining the existing Autodesk Inventor and SolidWorks integrations, hyperMILL® 2013 is released together with the hyperCAD-S® solution. This was developed by OPEN MIND specifically to address the requirements of CAM users.Source: OPEN MIND Technologies
