Creo 4.0 M090
I'm doing some 3-axis milling, simple 2D arc and line motions, and standard pecking drill cycles, etc. A strange thing is happening, apparently due to the part models involved. Here's a brief rundown of what I did.
A. Added reference model and workpiece.
B. Defined some milling sequences for those two parts.
C. NC-Check works fine, shows me a simulation of the material removal.
D. Added another reference model and its workpiece. Basically the next stage of manufacture of the part and the results of the previous steps.
E. Defined a milling sequence and some drilling cycles for the two new parts.
F. Now, NC-Check gives the message in the subject line above, not only for these new cycles and the operation containing them, but also for the previously completed sequences (in steps A and B).
So, the question is, what in the world have I done wrong? I've had this problem with specific sequences when I've had a cutter that is too small, or when there is a difference in accuracy between the parts or the manufacturing assembly, but all my accuracies in this case are the exact same value. I'm not doing anything sophisticated, just simple cutting around a shape defined by lines and arcs. How can adding more reference and workpiece models prevent simulation of previously defined sequences?
Luckily, since they're simple sequences, playing them without material removal simulation is good enough to see that they'll run okay, but I'm going to need to do some complicated surface milling on this stuff and I'd like to be able to verify that my programs are okay.
Anyone out there had this kind of fun before?
P.S. Sorry, can't upload models - proprietary and government related project.
