NX4 Sequential Mill Posted in NX7.5

[ValentUG]

If I open an NX4 Sequential Mill path in NX7.5 and run it through the same post with no changes to the path or post I get BIG differences in inverse time feed rates.

My Machine will bomb out every time.

Example:

NX4
X-.2483 Y1.49 Z15.7285 B-94.078 C-.015 F32934.659
X-.2492 Y1.4903 Z15.7284 B-94.071 C-.001 F40000.

NX7.5
X-.2484 Y1.49 Z15.7285 B-94.078 C-.015 F172466.162
X-.2492 Y1.4903 Z15.7284 B-94.071 C-.001 F424060.452

Any thoughts?

I ran into this with several posts as well. There is a fix for this. pb_cmd_fix_frn.tcl is a custom command that comes with NX7.5 to fix this problem.
