Delcam has launched the 2014 release of its Delcam for SolidWorks integrated CAM system, the first version to include the Vortex strategy for area clearance.

The software also includes a number of new options for turning, four-axis rotary machining and turn-mill operations, plus more strategies for two-axis finishing.

Full details on the new release and videos of the new functionality are on www.delcam.tv/dfs2014/lz.

Vortex (www.vortexmachining.com), for which Delcam has a patent pending, has been developed specifically to gain the most efficient material removal 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.

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.

Because Vortex toolpaths have a controlled engagement angle, tools should never be overloaded and so will achieve the maximum tool life. Shock loading caused by changes in the contact angle is minimised, preventing chipping of the flutes. In addition, the stability of the cutting conditions gives more consistent edge temperatures, so prolonging the life of the tool coating and removing heat damage to the surface of the part. Finally, the ability to use stepdowns of up to two, or even three times, the tool diameter spreads the tool wear evenly over the cutting surface of the tool, again contributing to longer tool life.

The first improvement to turning in Delcam for SolidWorks 2014 gives the ability to add fillets to any sharp corners, for example, for automatic deburring, without having to edit the geometry. The user simply has to specify the radiusNike
