reference "sim07_mill_5ax_fanuc_mm" in NX8.5

machine type is haed-table(BC)

I reversed the direction of the B and C axis.

The problem is that IJK values are output differently in G68.2 code block.

Likewise, the XYZ values are different.

Where can I change it?

I know about changes.

The problem is that it is changed incorrectly.

The current code is output as shown below.

I want to output it like the above.

mom_out_agle_pos is one of the input for computing rotation angles so if you change kinematics it changes rotation angles.

Try to find what type of angles are in this function g68.2 (euler zxz? xyz? zyx?)

Make sure that vericut interprets function with these angles correctly.

(I am not sure but plane euler fct (heidenhain) has no good behavior in vericut by default.)

I see also strange first approach XZ and the X. It should be XY and the Z. In cord. rot./3+2 machining/index functions you always mill perpendicular to XY plane.

Did you reverse the direction in both postprocessor and Vericut properly? They should match each other.

Fanuc function G68.2 works with Euler angles (ZXZ).

If there is any doubt in the results of Vericut vs G68.2, you can use another method of output for workplane transformation - G68, using the explicit values of *mom_out_angle_pos*.

*mom_kin_machine_type* in sim07_mill_5ax_fanuc_mm.tcl:

Instead *set mom_kin_machine_type "5_axis_head_table"*

specify *set mom_kin_machine_type "5_axis_dual_table"*
