CAM Software adds 5-axis options to accelerate machining.
Press Release Summary:
March 7, 2014 - By optimizing ordering of Vortex toolpaths to minimize lifts and air moves, PowerMILL 2014 R2 maximizes efficiency. Program includes dialogue to track position of machine tool, and toolbar to simulate and adjust configuration and tool axis of 3+2 machine. Plug-in provides graph of linear and rotary axes during simulation, allowing users to locate potential problems. To simplify 2.5D programming, software allows adjacent arcs, lines, curves, and surface edges to be merged into one composite curve.
Original Press Release
Delcam's New PowerMILL Offers Extra Five-axis Options and More
Press release date: February 26, 2014
The 2014R2 release of Delcam’s PowerMILL CAM software for high-speed and five-axis machining includes new options to machine parts and tooling with unprecedented speed and accuracy. New simulation and customisation tools, plus greater editing flexibility, give even greater opportunities to minimise programming times and reduce manufacturing times.
A series of improvements to Delcam’s unique Vortex high-efficiency area-clearance strategy is also included in the new release. Vortex gives fast, safe metal removal by allowing solid carbide tooling to cut with its full flute length so minimising machining times. At the same time, Vortex toolpaths use a controlled engagement angle between the cutter and the part, and so give a more consistent volume-removal rate and feedrate, minimising wear on the cutter. The main enhancement in PowerMILL 2014 R2 improves the ordering of the Vortex toolpaths to minimise lifts and air moves, and so increases overall efficiency.

The most important additions for five-axis machining are a new dialogue to track the position of the machine tool, and a new toolbar to simulate and adjust the configuration and tool axis of a 3+2 machine or any equipment with incremental rotary axes.
The new dialogue has a redesigned user interface giving improved presentation of data on the position of the machine tool, together with the limits set for each axis. It includes a slider to jog the machine components into position during the simulation and displays a warning if any axis limit is exceeded.
The new toolbar can be used to edit the tool axis and the orientation of the machine tool. This allows quick and easy updates to existing toolpaths with the new parameters. In addition, a new workplane that is aligned to the new axis and orientation can be created for subsequent programming operations.
Another addition that will be especially beneficial for five-axis programming is a new plug-in for PowerMILL that provides a graph of the linear and rotary axes of the machine during the simulation. Analysis of this graph allows users to locate any potential problems, such as sudden changes in direction or axis reversals that can adversely affect the surface finish. Adjusting the position of the part on the machine and running another simulation will often identify a solution to these problems.
A new method for creating composite curves has been added to PowerMILL that is based on similar functionality within Delcam’s PowerSHAPE CAD software. This allows adjacent arcs, lines, curves and surface edges to be merged into one composite curve, and so simplifies 2.5D programming and flowline machining.
The editing of curves has also been improved. It is now possible to insert and edit fillets within a composite curve. In addition, the tangents of a point on a Bezier curve can be modified, allowing more precise tangent editing. The number of points on a curve can also be edited and the points redistributed along the curve.
PowerMILL 2014 R2 has seen improvements made to optimise the raster strategies, giving less fragmented toolpaths, without any overlaps. The software eliminates automatically any small, isolated segments that can leave marks on the part’s surface. Removing these short moves also reduces lifting of the tool. Cycle times can be reduced further by minimising overlaps and so preventing over-machining in those areas.
Drilling has also seen numerous enhancements, including a separate strategy for each type of drilling cycle. New external threading and tapered threading options offer several settings to optimise the strategy. In addition, PowerMILL can scan the part to find any positions where holes intersect and then allows the break distance, feed rate and spindle speed to be adjusted through the intersections.
In a related development, the recognition, creation and editing of holes has been improved. There is now a dedicated dialogue for hole creation and a second dialogue to control hole editing and hole intersections.
Two new tool types have been added to the wide range supported by PowerMILL. Barrel tools, which are typically used for the manufacture of blades, are now supported. They allow a small cusp height to be achieved while using a relatively large stepover. The addition of dovetail tools allows easier machining of features such as undercuts and gears, which would otherwise require a series of more complex toolpaths with multiple tool changes.
Finally, two areas for customisation of PowerMILL have been enhanced. Firstly, the dialogue boxes for creating custom toolbars have been redesigned to improve their creation and management. The maximum number of custom toolbars has been increased from four to thirty-two and the ability has been added to export them in an XML file for use on other PCs.
Secondly, a number of commands and functions have been added to allow files to be created and manipulated. These allow files and directories to be copied or deleted, data to be extracted from lists using more succinct expressions, the names of active folders to be determined quickly and easily, and any sequence of edits to be automated, for example within a number of template projects.
