Exactly determine blank for milling path calculation

The Calculate milling paths for undercut areas tip explained that, as of Version 4.0 Release 4, blanks can be viewed from both sides for calculating milling paths. The large pocket in this part has already been milled and only the area outlined in red is to be roughed up with the "Nc3axJob/RPlan" function. However, the "Two-sided" option does not yield an optimal result here. What would be the best thing to do?

In the "Two-sided" option, the blank is viewed in the tilt direction and in the opposite direction for determination of the milling paths. The determined areas are then combined. Areas that no longer have to be machined and are "behind" the blank in both directions are not recognized. The image shows the one-sided (above) and two-sided (below) views for your example. However, it is also possible to determine the exact contour of the blank.

Here's how you do it

1.

Open the "Elements" dialog for the corresponding NCJob in the Job Manager.

2.

Select the "Exact" option for the "View" parameter.

3.

Start the calculation. The blank is decomposed in individual milling planes to determine the milling areas. The milling paths are only calculated for areas that actually have to be machined.

Hints

Note that calculation with the "Exact" option takes considerably longer. Therefore, if possible, this should only be used for corresponding geometries. 

You can learn more about viewing blanks with undercuts by calling up the context-sensitive help for the "View" parameter in the "Blank" area of the "Elements" dialog.
