The ability to visualize exactly the material that remains to be cut makes it much easier to create the most efficient machining operations and to determine their optimum sequence.
With NX 8.5 CAM you can improve NC programming time by as much as 10X for parts with prismatic features by using Volume-based 2.5D Milling. This new operation instantly displays the volumes machined by each operation and automatically updates the remaining workpiece material when you reorder them. Watch this short demonstration for an introduction to the concept. http://www.youtube.com/watch?v=FLBxaczgq1U&hd=1 NX CAM - Introduction to Volume-based 2.5D Milling
Volume-based Milling can also reduce machining time because the operations automatically adjust the toolpaths to the size of the stock to eliminate wasted air-cutting.
