Whether racing cars or motorcycles, winning teams design and manufacture premium, optimised components to meet a wide array of challenges. On the racetrack, vehicles battle to outpace one another by hundredths of a second – there’s virtually no room for error. Similarly, component manufacturing calls for achieving the greatest dimensional accuracy, the highest surface qualities and contour accuracy for free-form surfaces, without making any compromises.
Motorsport involves a particular challenge: Changes to vehicles must be quickly and flexibly implemented, so the teams can start off the next race with better systems on board.
Racing-related applications typically involve challenging geometries for which a great deal of material needs to be machined. hyperMILL® offers sophisticated high-speed cutting (HSC) and high-performance cutting (HPC) strategies that guarantee optimal roughing and finishing processes, even for material that is difficult to machine. This in turn ensures tool- and machine-friendly machining with high material removal rates. The unique 5-axis HPC strategies from OPEN MIND make it possible for even the deepest cavities to be roughed as quickly as possible and without collisions using short clamped tools. The high-performance finishing module of hyperMILL® MAXX Machining achieves time savings of up to 90 percent, thanks to the use of barrel cutters. It also delivers perfect surfaces.
Adaptive pocket/High-Feed Cutting (HFC)
hyperMILL® offers a large number of functions for HSC and HFC machining. Using a freely definable tool geometry makes it possible to precisely map high-feed cutters, which are then taken fully into account during collision checks and rest material computation. Machining times can be reduced in connection with the ‘adaptive pocket’ function, whereby circular or rectangular pocket geometries are automatically adapted in the area to be machined.
Rest machining
5-axis rest machining offers all the options of 3D rest machining in addition to the 5-axis tool positions. Automatic indexing independently determines the positions and areas that allow the workpiece to be completely machined in a single operation.
HPC roughing
Trochoidal toolpaths enable efficient roughing of pockets and open areas with large material removal rates. The particularly high axial infeeds and low lateral infeeds ensure tool-friendly roughing with a peeling cut.
5-axis helical drilling
Using this strategy, the material is milled from a circular pocket based on helical tilt milling in a 5-axis simultaneous movement, which is particularly efficient and tool-friendly, even when handling difficult-to-machine materials.
Finishing with Barrel Cutters
This method allows users to achieve time savings of up to 90 percent during tangent plane machining. The use of conical barrel cutters allows for larger line increments while delivering a better surface quality at the same time, compared to conventional finishing methods.
Tube package
The ideal solution for intake and exhaust tubes for engines as well as pipe inlets and outlets for pumps and compressors: 5-axis tube machining makes it possible to machine strongly undercut geometries on the basis of the simplest guide curves. The proven collision check and avoidance system ensures safe 5-axis milling operations.
Feature and macro technology plays an important role in CAM automation that makes daily work easier for all programmers. hyperMILL® recognises features such as holes, threads and fittings automatically. These features can be used manually or automatically for NC programming. Macros that can be used to save entire machining sequences enormously reduce the amount of programming required. Programmers’ manufacturing knowledge is stored in the macro database and can be retrieved by all employees at any time. Users can quickly respond to geometry changes using this database. Thanks to standardisation and automation, programmers also avoid possible application errors.
As it is for delivery times, so it is for racetracks: Speed is decisive in motor sports. Efficient manufacturing with absolute process reliability is necessary in order to uphold tight delivery deadlines and deliver just in time.
When toolpaths are calculated with the hyperMILL® CAM software, the collision check is already incorporated, and reliable simulation technologies make it possible to master the machining of complex 5-axis integral components at any time.
