Delcam Enhances Vortex in PowerMILL 2015

Delcam has released the 2015 version of PowerMILL, their flagship CAM system. Major enhancements include a couple of improvements to their Vortex high-efficiency area clearance strategy apart from the improved collision checking to also cover near misses and more efficient raster finishing. According to the press release,

The Vortex area-clearance strategy produces safe toolpaths with a much deeper cut by using a controlled engagement angle that maintains the optimum cutting conditions for the whole toolpath.  As a result, higher feed rates and material-removal rates are possible, making the cutting time shorter by as much as 70%.  In addition, cutting is undertaken at a more consistent volume-removal rate and at a near constant feedrate, so extending tool life and protecting the machine.

Two enhancements in PowerMILL 2015 will give even greater reductions in machining time with Vortex compared to conventional roughing. The first change allows toolpaths to approach the part from outside the stock at the cutting height, both for open pockets and in areas where earlier cuts have made this possible.  Previously, all entry moves had to be made by plunging onto the surface or by ramping into the material.

The second change allows an increased feed rate to be set for non-cutting moves. The default value is set at double the rate for the cutting moves but this can be altered as required for each machine tool.  The extra time that can be saved depends on the shape of the part but an additional saving of around 20% should be expected above the earlier releases of Vortex.

Here is a video explaining the Vortex improvements.
