Software maximizes five-axis machining

TNP_DelcamPowerMill5.gifPowerMill 5 incorporates a wide range of five-axis machining strategies combined with easier programming, plus features such as improved rest roughing, variable-thickness machining, more comprehensive collision checking, and a new simulation option. Most important, says the manufacturer, is the rest roughing, which reportedly accelerates calculation times and lets each tool remove the maximum material possible.

Delcam?s stated goal continues to be generating toolpaths that not only are mathematically correct but that also run efficiently. In PowerMill 5, secondary axis limiting has been added to ensure that the generated program does not try to move beyond the machine tool?s range of movements. Contact point analysis lets the user be sure that only the cutting surface makes contact, and that any rubbing with the shank is avoided. To help cut some of the more difficult materials on the market today, Delcam has added contact point feedrate control that lets the feedrate be set based on cutting speed rather than the tool tip?s rotation rate.

The user also can increase control over cutting conditions by editing individual segments within any toolpath to accommodate conditions in different areas of the piece, and the program can be reordered for more efficient machining of large parts. Similarly, the user can edit toolpath leads and links for cases where it is not possible to use the same style of lead and link for the entire piece. Five-axis drilling can be faster thanks to more comprehensive hole recognition across a wider range of CAD systems and the automatic capping of holes to prevent the milling cutter from entering them.
