Making 2.5 axis or 3 axis cuts at several different index positions is often called 3+2 machining. For z-level cuts in NX CAM, this approach is particularly easy to accomplish. This Tech Tip describes an easy way to program a sequence of Z-level operations at multiple tool axis orientations without creating multiple MCS geometries.
This Tech Tip was created with NX 8.5
Create your MCS using either the Mill_contour or Mill_multi-axis template (Do not use the mill_planar template)
Customize your Zlevel 5 Axis operation to include the ‘Tool Axis’ option
Now that your Z-level 5 Axis operation includes the Tool Axis option, specify this option as either Specify Vector or Dynamic
For Specify Vector, set the Tool Axis to the appropriate vector for each operation
Generate the tool path
