High-speed roughing strategy to be launched at EMO

Delcam will launch its new Vortex strategy for high-speed area clearance on stand K18 in Hall 25 at the EMO exhibition to be held in Hannover, Germany, from 16th to 21st September.  Vortex will be the major enhancement for the 2014 release of Delcam’s PowerMILL CAM system for high-speed and five-axis machining that will be demonstrated for the first time at the show.

Delcam’s new Vortex toolpath strategy reduced the machining time by 71% for this component in tool steel.

Vortex, for which Delcam has a patent pending, has been developed by the company specifically to gain the maximum benefit from solid carbide tooling, in particular those designs that can give deeper cuts by using the full flute length as the cutting surface.  It can be used for two- and three-axis roughing, three-plus-two-axis area clearance and for rest machining based on stock models or reference toolpaths.

Huge savings
The benefits of using the Vortex strategy will vary depending on a number of factors, including the material and shape being cut, and the machine tool and cutting tools being used.  A series of trials run by Delcam on different machine tools within its Advanced Manufacturing Facility has shown that a time saving of at least 40% is not untypical, with the biggest percentage savings being found when cutting tool steel on a Huron machine with SGS Z-Carb MD cutters.  The cycle time for the sample part was reduced from 121 minutes to 34 minutes, a reduction of 71%.

Under control
Unlike other high-speed roughing techniques that aim to maintain a constant theoretical metal-removal rate, the Vortex strategy produces toolpaths with a controlled engagement angle for the complete operation.  This maintains the optimum cutting conditions for the entire toolpath that would normally be possible only for the straight-line moves.  As a result, the cutting time will be shorter, while cutting will be undertaken at a more consistent volume-removal rate and feed rate, so protecting the machine.
