If you don’t use Post Builder, or have many posts using the old solver in Post Builder 3.3 or earlier, you can continue to use these legacy variables. Set mom_kin_iks_usage to 0, or leave the variable undefined, to use the legacy kinematics variables.

mom_kin_pivot_gauge_offset |
mom_kin_4th_axis_point |
Kinematics |
For four and five axis tilting head machine tools only. Defines the distance from the pivot point of the tilting rotary axis to gage point. This value can be negative. This value is added to the tool length to determine the effective length of the tool. You must call MOM_update_kinematics after specifying this variable to map to its replacement. |

Numeric Value |
0 |
|
mom_kin_iks_usage |
mom_kin_iks_usage |
Kinematics |
Determines which version of inverse kinematics solver (IKS) to use. The IKS defines how X,Y,Z,I,J,K values are converted to X,Y,Z,A,B for four and five axis machine tools. Set mom_kin_iks_usage to 1 to use the new IKS from NX 3 or later. If you don’t set the variable or set it to any value other than 1, the old IKS from NX 2 will be used, and there should be no changes in the output. If you’re using Post Builder 3.4 or later, mom_kin_iks_usage is set to 1 and the new IKS is used. If you are using any other posts for complex machines, you must set this variable to 1 to use the new method. Note: Non-orthogonal axes and the head object are only available with the new IKS. |
