The NURBS XZ cycle is a Vertical Slicing cycle for cutting solids and surfaces inside of AutoCAD. Tool paths will be generated in the X direction as slices following the contour of the shape in Z. The slices can be made in one direction, or laced together to allow slicing in both X directions (positive and negative), forming a zig-zag motion of the tool.
Essentially the NURBS XZ cycle is the same as the NURBS YZ cycle with a Slicing Angle of 0.0°.
There are many parameters available to fine tune this cycle to perform many operations and these will be described throughout the NURBS section of this document. |
Shown is a tool path created with the default settings of the NURBS XZ cycle. Similar results can be obtained by selecting the cycle and simply pressing the cut button and selecting the solid model. When prompted at the command line:
Enter Surface Tolerance <0.00050000>:
Enter .003
Enter Surface Tolerance <0.00050000>: .003
You should see the same tool path as the picture above. The surface tolerance is the amount of deviation allowed for the tool path to follow the surface of the part as it breaks the moves up into small line segments for each pass. The smaller this number is, the more closely the tool path will follow the part contours, but the segments of the cut will be smaller, and thus produce more NC Code.
**Changing values in the cycle parameters may yield unexpected results with some settings or on some geometry. Examine the toolpath and NC Code carefully before running your machine tool if you change these default settings.
