Large bore roughing
My Monday morning annoyance with Creo is with the way I rough large diameter bores. I generally use a mill window with a helical ramp into the part. Then do a spiral rough tool path out to the required diameter with stock left on the profile.
This method seems really efficient to me but the major problem I have is I would like the end of the tool path to have a lead off amount to get the cutter off the wall for the retract out of the bore. I set all the parameters in the sequence for this lead off but I will not work.
Picture of the tool path with the cutter retracting straight up the wall.
what I have found is you need to go into the tool motion and manually add a lead out to get this to work at the end in order for the lead out to work even though the parameters are set.
I think this is another problem with the software.
