Z Level with Reference Tool
What is it?
With Z Level Reference Tool, you can finish-mill corners using Z level cuts. The cuts are similar to Z Level Profile operations, but limited only to corner areas that a defined previous tool could not reach due to its diameter and corner radius.
Why should I use it?
Use Z Level Reference Tool when you want to remove a small amount of blank material from corner areas. This operation would typically follow a finish operation by a larger tool, which could not finish the corner areas.
Where do I find it?
Manufacturing --> Create New Operation --> Mill Contour --> Z Reference Tool. You can use this in existing Z Level profile operations by adding the previous tool item with customize dialog.
Automatic Wall Identification in Face Milling
What is it?
With Automatic Wall Identification, the Face Milling processor automatically recognizes and applies wall stock to faces adjacent to the selected cut area faces, satisfying the documented wall criteria.
Why should I use it?
Use Automatic Wall Identification when cut area faces have adjacent walls that can be automatically recognized using the documented wall criteria. This saves time because you can apply wall stock to the necessary faces without having to select the faces individually.
Where do I find it?
Automatic Wall Identification is available on the Face Milling dialog.
Cut Area in Face Milling
What is it?
With Cut Area, you can use flat cut area faces to define the machined faces for a Face Milling operation.
Why should I use it?
Use Cut Area when face geometry alone, without boundaries, is sufficient to define the machined faces on a part body, or when the machined faces have finished walls requiring a unique stock.
Where do I find it?
You can define Cut Area inside a Face Milling operation or inherit it from a MILL_AREA geometry group.
Pre-Select Wall Geometry in Face Milling
What is it?
You can use Pre-Select Wall Geometry to initialize wall geometry based upon the cut area faces. You retain the ability to remove, edit or append items from Wall Geometry.
Why should I use it?
Use this functionality when most, but not all, of the wall geometry adjacent to the cut area faces can be selected using the documented criteria for Automatic Wall Identification.
Where do I find it?
You can find the Pre-Select button inside the Select/Edit dialog for Wall Geometry.
Wall Stock and Wall Geometry in Face Milling Operations
What is it?
Now, you can select faces on the part body (other than the faces being machined) as wall geometry and apply a unique wall stock to those faces in place of part stock.
Why should I use it?
Use wall stock and wall geometry when you are machining faces that have finished walls requiring a unique stock other than part stock.
Where do I find it?
Select wall geometry inside a face milling operation, or inherit from a MILL_AREA geometry group.
Define wall stock in the Cutting Parameters dialog for a face milling operation.
Zig Zag 3D Stepover
What is it?
With Zig Zag 3D Stepover, you can direct the system to calculate the patterns to maintain a specified distance between tool paths. This distance can be either in the plane normal to the tool axis or the actual distance measured between the nearest tool path motions across successive passes. With this pattern you specify a cut type in successive parallel cuts. This adds to the existing functionality of Follow Periphery introduced in Unigraphics NX1.
Why should I use it?
Use Zig Zag 3D Stepover when you are machining parts that have steep and non-steep regions over the part surfaces using the parallel pattern. Use this to control scallop height, especially in steep areas, but maintain the maximum stepover in 3D, measured along the part.
Where do I find it?
Area Milling Operations --> Drive Parameters dialog. Change Apply Stepover to On Part.
Tangential Extensions
What is it?
With Tangential Extensions, you can extend tool paths tangentially past the external edges of the cut area.
Why should I use it?
Use Tangential Extensions when you want to machine excess material around the part. You can also use it to add cutting moves to the start and end of tool path passes to ensure that the tool smoothly enters and exits the part.
Where do I find it?
Tangential Extensions is located on the Cutting Parameters dialog for Flowcut, Area Mill, and Zlevel Profile operations.
2D Contact Contour
What is it?
With 2D Contact Contour, you can select the tracking point (as indicated by the number one in Figure 1) to output the contact contour tool path.
Figure 1
Why should I use it?
Use this when you would like to output the specific tracking point to the tool path.
Where do I find it?
The Output Contact Data toggle is located in Machine Control --> Cutter Compensation dialog.
