4. The Main Function Modules of NX CAM Postprocessing Post Builder creates and edits postprocessors. These post- processors have three elements. NX CAM ***.pui ***.tcl ***.def

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. NX CAM

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

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. NX CAM

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. NX CAM

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. NX CAM
