Delcam GmbH to Show Latest in CADCAM for Toolmakers at Euromold
Delcam GmbH will demonstrate the 2013 releases of Delcam’s PowerSHAPE CAD software and PowerMILL CAM system at the Euromold exhibition to be held in Frankfurt from 27th to 30th November. Both new programs include significant enhancements to enable toolmakers to increase productivity, reduce lead times and improve quality, regardless of whether they are making moulds of any type, press tools or die-casting equipment.
With its unique combination of solid modelling, surface modelling, direct modelling and triangle editing capabilities, PowerSHAPE provides a comprehensive range of design and reverse engineering techniques. Having all the different technologies in the same package reduces the need to transfer data between multiple programs and so streamlines the whole process of tooling design.
In particular, the combination of quick and easy direct modelling options, together with powerful and flexible surface modelling, makes PowerSHAPE the perfect choice for the design-for-manufacture modifications that are needed when converting product designs into successful tooling designs.
PowerSHAPE also includes the Solid Doctor, a comprehensive set of tools for the repair of CAD models from all sources, including IGES, STEP and native CATIA and Creo files. It can be used to tackle all the common problems that are found when translating low-precision and incomplete data, including gaps and overlaps between surfaces, or duplicated and missing surfaces, and generate a valid, high-precision solid model.
Enhancements in the 2013 release of PowerSHAPE include improvements to its direct modelling and reverse engineering capabilities that will make the software both more flexible and even easier to use, plus solid and surface modelling options that have been made faster and even more robust.
The major new development in PowerMILL 2013 will be the Vortex area clearance strategy. This has been developed 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.
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.
