5-axis CAM has fast calculation times
As well as offering additional options for 5-axis machining, CAM software includes improved memory management within the software to give significantly faster calculation times.
Latest version of Delcam's PowerMILL CAM system features a range of enhancements aimed at reinforcing its position as the world's leading specialist CAM software Like other recent versions of the software, a major focus of PowerMILL 8 will be additional options for five-axis machining

PartMaker CAM programs mill-turn centres
Delcam has launched the latest version of its PartMaker family of software, which now offers programming of turn-mill equipment and Swiss-type automatic lathes.
FeatureCAM supports advanced mill-turn centres
Delcam's latest FeatureCAM version offers more support for advanced CNC mill-turn centres with multiple turrets and/or multiple spindles.
However, the new release also includes enhancements and speed-ups throughout the program.
Improved memory management within the software will give significantly faster calculation times, especially for large, complex components, like press tools for automotive bodywork, and for smaller, highly-detailed models, such as moulds for fine-tolerance and high-accuracy parts.
* Powerful tool-axis editing function - the most significant of the new five-axis options, said Delcam to Manufacturingtalk, is a powerful tool-axis editing function that allows the user to select any region of a toolpath and redefine the tool-axis vectors within that region.

Previously, a single tool-axis specification was applied to a complete toolpath, although this could be adjusted automatically to avoid any collisions.
The new ability to use different options in different regions of the toolpath will enable users to optimise cutting conditions and avoid any sudden machine tool movements that could result in a poor surface finish.
Five-axis swarf machining has been improved by the addition of an option that forces the toolpaths to follow the surface internal lines where possible.
This approach can be used to give smoother motion of the machine tool and more precise control of the machine, especially in tight corners and other areas where there could be rapid changes in the cutter orientation.
An improvement to area clearance toolpaths with both positional 5-axis operation and 3-axis machining allows the user to add different styles of 'tails' to the toolpath under certain stepover conditions.
These extra moves are needed to remove any upstands that might otherwise be left when cutting with a stepover more than 50% of the tool-end diameter.
The new options will give smoother toolpaths and will maintain the cut direction as either climb or conventional.
* Large abrasive disk cutters - PowerMILL has always supported a wide variety of cutting tool types.
This range will be further extended with the addition of machining strategies specifically for large abrasive disk cutters within PowerMILL8.
The new options include specific types of leads and links, plus dedicated gouge prevention functionality, to allow these disks to be used to cut around corners safely and accurately.
To make it easier to manage the wide range of tooling that is supported by PowerMILL, an easy-to-use tool database has been added to the new version that allows the user to perform a search operation to find the required tool.
The enhanced tool database, which will be shared with the recent release of FeatureCAM, will also be able to support much more information on recommended feeds and speeds taken from suppliers' tool catalogues.
Simulation and verification on the computer has become increasingly important for many users and the PowerMILL development team has introduced a number of improvements in this area.
In PowerMILL 8, ViewMILL simulations will be able to be created and viewed with a full three-dimensional model of the stock.
This allows the user to rotate the ViewMILL machining model and view it from any direction both during and after the simulation.
In addition, the user interface has been streamlined so that both cutting tool simulation and machine tool verification can be controlled from a combined toolbar. Request a free brochure from Delcam ...
