Delcam’s Vortex area clearance to be shown during OSG “Train the Nation” tour

A demonstration part machined using Delcam’s Vortex high-efficiency area-clearance strategy and OSG tooling

Delcam’s Vortex high-efficiency area-clearance strategy will be demonstrated during a series of die/mold training events to be held by OSG Tap & Die across the Midwest between June 25th and November 5th.  For a full list of dates and venues, please go to

Each of the one-day training events will show machinists how they can provide better results and achieve more productivity from their machines.  OSG Tap & Die operates at the cutting edge of tooling and software technology.  During the seminars, company experts will share with delegates the best tips and techniques to take their machining capabilities to the next level. 

The Vortex strategy, which was recently announced to be the Best CADCAM or Control System at the MWP Awards, offers substantial time savings by allowing deeper cuts to be made using the full flute length of solid carbide tools as the cutting surface.  Trials run by Delcam have shown that time savings of up to 70% are possible with the new strategy.

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 significantly shorter, while cutting will be undertaken at a more consistent volume-removal rate and feed rate, so protecting the cutter and 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 three, or even more, times the tool diameter spreads the tool wear evenly over the cutting surface of the tool, again contributing to longer tool life.
