Delcam's 64-bit PowerMill CAM delivers results, faster

Sixty-four-bit technology removes the memory limitations of 32-bit computers, allowing more efficient toolpath generation, especially for companies machining large or complex parts. The 2010 release also continues to improve user productivity by extending the use of the latest background-processing and multi-threading technologies available in recent hardware. The combination of these two developments is estimated to reduce calculation times by up to 25 per cent, although this will depend on the size and complexity of the part. In addition to the hardware-related performance improvements, PowerMILL 2010 includes more than 50 other major enhancements to give faster and easier programming, more efficient toolpaths and better surface quality in the finished parts. This is the largest number of improvements in a single release for over five years and reflects the continued high levels of investment in product development at Delcam. The most obvious change for existing users will be an updating of all the toolpath-creation forms to a new and improved layout. The forms make it simpler for new users to find the commands they need, while also giving experienced operators more logical access to the more advanced options. In addition, there is a new toolbar for faster and easier creation and editing of workplanes. A new series of strategies for the roughing and finishing of corners has been added. These give more efficient and smoother clearance of these areas, especially when a large tool has been used for roughing initially that has left a significant amount of material in the corner. Rest roughing has been enhanced to give better control over the start points for each segment of the toolpath. This will give substantial savings in overall machining time by minimising any air cutting. Offset roughing, a popular approach for high-speed machining, has been enhanced so thin slivers of material that may damage the cutter are not left for the final pass. PowerMILL will now identify these potential problems automatically and adjust the final stepover to give more even and, therefore, safer material thicknesses. A number of improvements have been made to give smoother toolpaths for semi-finishing and finishing. In a related development, more options have been added to the collision avoidance functionality to give more control over the direction chosen by PowerMILL to avoid the problem. Constant-Z toolpaths have been enhanced to include the detection of flat areas and the automatic insertion of extra Z-levels to machine these exactly. In addition, a filter has been added to remove small enclosed segments from the toolpath, as these can damage the cutter. The 'Steep and Shallow' machining combination strategy uses these latest additions for the steep sections and a range of new options has been added for the shallow areas. Finally, a new option has been added that specifies the safe profile of the toolholder for any group of toolpaths.
