15. 4. The Main Function Modules of NX CAM
Lathe
Lathe enables you to rough out Blank material prior to finishing. You must specify Part and Blank boundaries and then set options.

16. 4. The Main Function Modules of NX CAM
Planar Milling
Use Planar Milling to create tool paths along vertical walls or walls that are parallel to the tool axis.
NX CAM

17. 4. The Main Function Modules of NX CAM
Cavity Milling
Use Cavity Mill operations to remove large volumes of material. Cavity Mill is ideal for rough-cutting parts. Part Geometry can be planar or contoured.

18. 4. The Main Function Modules of NX CAM
Fixed-axis/ Variable-axis Milling
Fixed-axis Surface Contouring operations and Variable-axis Surface Contouring operations finish areas on contoured surfaces by removing material along the part contours.

19. 4. The Main Function Modules of NX CAM
Sequential Milling
Sequential Milling is designed to machine a series of edge-to-edge surfaces in succession. It is used to finish surfaces once the area has been roughed out using Planar or Cavity Milling.
