The 2014 release of Delcam's PowerSHAPE CAD system includes many new features for you to enhance your CNC machine tool with PowerSHAPE. They include faster and more reliable data translation, unique tools to fix problem parts quickly, flexibility to allow you to work the way you want, ability to re-create parts from scannd data, powerful analysis tools to spot potential issues in a part and direct modeling tools to modify complex geometry quickly and simply.
For programming of complex parts the new version of Delcam's PowerMILL CAM system includes new and enhanced strategies for both roughing and finishing of 3 to 5-axis parts.
As the developer of the world's leading specialist machining software with the largest development team in the industry, Delcam is uniquely placed to provide solutions that are both powerful and practical. Delcam's range of complete automated CADCAM solutions can help companies from concept design through to the manufacture.
No matter what market or what machines you use, Delcam has proven technology to ensure prompt and efficient delivery of products to market.

Delcam will demonstrate its new Vortex strategy for high-speed area clearance on booth E-3222 at the IMTS exhibition to be held in Chicago from 10th to 15th September. Vortex will be the major enhancement for the 2013 release of Delcam’s PowerMILL CAM system for high-speed and five-axis machining that will be launched at the show. The new strategy will also be added to the FeatureCAM software for feature-based programming and the PartMaker system for programming Swiss-type lathes and turn-mill equipment later in the year.
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.
Like other Delcam roughing strategies, Vortex toolpaths are calculated to give more efficient machining by following the shape of the part and by keeping air moves to a minimum. This is particularly important for rest machining operations.
One fundamental problem with conventional area-clearance strategies is that the optimum cutting conditions only occur during a straight-line cut. Any internal corners within the model significantly increase the engagement angle of the cutter. To protect the cutter, this increase needs to be balanced by setting a lower feed rate. The user then has the choice of using this lower rate over the whole toolpath, which increases the machining time, or varying the feeds and speeds as the cutter moves around the model and so increasing wear on the cutter.
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 will 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.
"Anyone using the Vortex strategy will be able to hear the difference immediately,” claimed Mark Forth, Product Manager for Delcam’s Advanced Manufacturing Solutions. "Conventional roughing produces a sound of varying pitch, which indicates tool overload and chatter, while Vortex roughing gives a constant pitch, showing that the tool is operating under consistent conditions. Users will also be able to see the difference in the regular size and thickness of the chips produced, providing further evidence of the consistency of the cut.”
The new Vortex toolpaths benefit from the general advantages of PowerMILL, including support for 64-bit computing and multi-processor operation to minimise calculation times, plus the comprehensive options for leads and links. Furthermore, they can be used in association with the step-cutting strategy introduced in PowerMILL 2012 R2. This approach minimises the terracing that can result from using a large stepdown by moving back up the part and automatically generating extra toolpaths to remove additional material at intermediate slices. It optimises the amount of material that can be removed with a single tool as well as helping to maintain a more consistent removal rate by increasing the feed rate for the intermediate slices
