Operation subtypes that use the Face Milling processor cut planar faces on solid bodies. For example, pads on a casting.

Operation subtypes that use the Planar Milling processor follow 2D boundaries to remove material along vertical walls, or walls that are parallel to the tool axis. Planar Milling removes material in planar levels that are perpendicular to a fixed tool axis. The areas on the part to be machined can include planar islands and planar floors that are normal to the tool axis.

The Planar Milling 2D Profile processor cuts a single profiling pass along a part boundary.

Operation subtypes that use the Planar Milling 3D Profile processor cut one or more profiling passes along 3D part geometry. The depth is determined by the edges or curves in the boundary. These operation subtypes are often used for trim dies.

The Planar Text processor engraves drafting text directly on a planar surface. Drafting text can include part numbers and mold cavity ID numbers.

Operation subtypes that use the Cavity Milling processor remove large volumes of material. Cavity Milling removes material in planar levels that are perpendicular to a fixed tool axis. Part Geometry can be planar or contoured. Cavity Milling is ideal for rough-cutting parts, such as dies, castings, and forgings.

The PLUNGE_MILLING processor cuts vertically to take advantage of the increased rigidity when a tool moves along the Z-axis. Plunge Milling efficiently roughs out large volumes of blank, and lets you finish hard-to-reach deep walls with long slender tool assemblies.

Operation subtypes that use the Z-Level Milling processor contour a part or cut area. Z-Level Milling removes material in planar levels that are perpendicular to a fixed tool axis. Part geometry can be planar or contoured.

The Variable-axis Z-Level Milling processor lets you tilt the tool axis away from part geometry when contouring a part or cut area with a multi-axis machine.

The Sequential Mill Main processor finishes surfaces that have been roughed out using Planar Milling or Cavity Milling. Sequential Mill allows you to carefully follow surface contours using three-axis, four-axis, or five-axis tool movements while exercising a high degree of control over each sub-operation of the tool path.

Operation subtypes that use the Fixed-axis Surface Contouring processor contour a part or cut area. Fixed axis Surface Contouring removes material along the part contours.

Operation subtypes that use the Variable-axis Surface Contouring processor contour a part or cut area. Variable-axis Surface Contouring removes material along the part contours.

Operation subtypes that use the Generic Motion processor position tools for different applications. Generic Motion supports machines with up to five axes of freedom.

Operation subtypes that use the Mill User-Defined processor generate tool paths from a custom NX Open program.

The MILL_CONTROL operation contains only machine control events.
