To Define a Cut Using Surface Isolines
Use this method to mill a single surface, or several continuous surfaces. The machining direction is defined by the natural u-v contour of the surface to be milled. If multiple surfaces are selected, the machining direction is determined separately for each surface.
1. In the top portion of the Cut Definition dialog box, select From Surface Isolines.
The system displays the names of the surfaces selected for milling in the Surface List list box.
2. Select a surface name in the list box to preview the cut direction.
3. For each selected surface, you are given a choice of two directions, determined by the u-v lines of the surface. Click
, if necessary, to toggle between these directions.
4. If more than one surface is being machined, they will be milled in the same order as they are listed in the list box. You can reorder the surfaces using the following methods:
◦ Select a surface name in the list box, then click the Up Arrow and Down Arrow icons to move it up or down in the list.
◦ Click
to reorder the surfaces by selecting them on the screen.
5. If you click
, the
CNTR ORDER menu appears with the options:
◦ Next Surface—Select the first surface to be milled. This option will highlight automatically after each selection allowing you to select surfaces in the order you want them to be milled.
◦ Done Order—Select this option when you have specified all the surfaces you want to be milled in a specific order. You do not have to order all the surfaces selected for milling: when computing the CL data, the system will mill the ordered surfaces first, and then mill any leftover surfaces.
6. When satisfied with the cut direction and the surface order, click OK.
