Save the Specified Tool Axis
Saving the specified tool axis in fixed axis operations.
Answers for industry.
About NX CAM
NXTM CAM software has helped many of the world’s leading manufacturers and job shops produce better
parts faster. You can also achieve similar benefits by making use of the unique advantages NX CAM
offers.
This is one of many hands-on demonstrations designed to introduce you to the powerful capabilities in
NX CAM 11.0.1. In order to run this demonstration, you will need access to NX CAM 11.0.1.

Hands-on Demonstration: Save the Specified Tool Axis
On multi-axis machine tools, multiple machine tool axis angle positions may be valid for cutting the part.
NX now saves the specified tool axis with the operation. Prior to this enhancement, if you changed the
tool axis in a fixed axis operation to a preferred alternative the tool axis would not be saved.

Prerequisites:
1. You will need access to NX CAM 11.0.1 in order to run this demonstration.
Demo:
For this demonstration, you will retrieve a part file and machine tool assembly from the NC
Simulation Samples library.
1. Select MenuHelpManufacturing Tutorials.
2. In the Shortcuts section at the bottom of the Manufacturing Tutorials home page, select Open a
Sample Part.
3. Scroll down and select sim08_mill_5ax_cam_fanuc_mm.prt from the NC Simulation Samples
list.
4. Click OK in the Open dialog box.
5. In the Program Order view of the Operation Navigator, double-click FACE_MILL_FLOOR to edit
the operation.
In the Tool Axis section of the dialog box, the A and C angles are now displayed for the current
tool axis.
4
6. Click OK.
7. Click Simulate Machine
in the Ribbon Bar.
8. Slow down the Animation Speed to 3 and click Play
.
Notice the orientation of the tool axis relative to the A and C axis of the machine tool.
9. Click OK.
There are two valid tool axis solutions that can be used to machine the face in this operation,
each defined by different A and C values.
Solution 1
Solution 2
The operation currently uses solution 1. In some cases, you may wish to use solution 2 (due to
machine tool limitations or interferences).
5
10. Double-click FACE_MILL_FLOOR to edit the operation.
11. Select Dynamic from the Tool Axis list.
12. Double-click the XC vector to reverse the direction.
Notice that the A and C values have been changed to reflect the new tool axis. These values are
now saved with the operation.
The selected axis values are available in two new mom variables (mom_preferred_fourth_angle
and mom_preferred_fifth_angle) and it is possible to adjust the postprocessor to make use of the
selected values.
13. Click Generate
14. Click OK.
.

15. Click Simulate Machine
16. Click Play
in the Ribbon Bar.
.
Notice the new orientation of the tool axis relative to the A and C axis of the machine tool.
17. Click OK.
18. Continue practicing.
19. When you are finished, close the part without saving.
