NX 5 axis postprocessor designed for Rotary output gives Vector output in some cases.

The Five axis postprocessors created in older versions work fine in NX9 or NX12. But when used in NX1980 and above it gives vector output in some cases.

This vector output is undesired and need only rotary output.

Refer to the below image with the issue.

Note: This typically happens if the rotary axis crosses the limits such as A0.

Solution

There is an enhancement in NX1980 which will detect rotary axis cross limit when rotary axis limitation is 0~360.
This change causes a warning event which was not in NX12 but now generated in NX1980 when A axis rotated from 3 to 356 for example.
 This is the cause of the issue.
 
 
 
It can be simply fixed in .tcl file of the postprocessor by changing mom_sys_5th_axis_has_limits to 0.
 
 
  set mom_sys_5th_axis_has_limits               "0"  





Steps:
1. Open .tcl file of the postprocessor in Notepad or Text Editor
2. Search for mom_sys_5th_axis_has_limits
3. Set value from 1 to 0
4. Save the file.
5. Test the output.

The vector output problem should be resolved.
