Delcam will launch the 2012 version of its PowerMILL CAM system for high-speed and five-axis machining at the EMO. The new release will include a number of new strategies, together with more general enhancements to make programming faster and machining more efficient with the best-possible surface finish.
The most important new option is flowline machining. With flowline machining, the toolpath is divided between a pair of drive curves in a constant number of passes, rather than having a varying number of passes with a constant stepover. The toolpath will have its start and end passes on the drive curves, with the intermediate passes blending between them.
Better surface finish with flowline
This approach gives smoother results since it ensures that each pass travels over the full length of the area, rather than leaving the part, or making major changes in direction, during the pass. It produces a better surface finish on the part and minimises wear on the cutter and the machine tool.
New option – spiral machining
PowerMILL has offered an optional module for automated machining of blades, blisks and impellors for some time. This module has now been enhanced with the addition of a spiral machining strategy. This keeps the cutter on the surface of the part for the complete operation and so gives more even tool loading and a better surface finish.
New option – control the angular point distribution
Another new option that will give better results during five-axis machining is the ability to control the angular point distribution. This option can be used to keep the machine tool moving smoothly when there is rapid angular change in one of the rotary axes of the machine tool. Smoother tool-axis changes can be achieved by increasing the density of the points in these areas. This gives a more even movement of the machine and so gives a better surface finish, with no risk of dwell marks. The smoother motion also reduces wear on the machine.
Many other enhancements to discover
- The ability to use Bezier curves rather than polylines
- more control over the clearance distances applied to the cutter and its holder
- thread milling options
- workplane editing
- Z-height selection and limiting, have been made easier.
- It has also been made easier to obtain measurements
- the use of the PowerMILL macro language to programme repeat operation has been extended
To be discovered at EMO, hall 25, booth H25
