NX thread cycle for an OKUMA Lathe
Hi, can anyone help with a thread problem I'm having on an OKUMA using an NX 7.5 program. The tool goes into its start point, feeds in cuts the thread, but instead of the tool feeding up on the “X” value and out to the start point to do its second pass, it feeds back on the “Z” value re-cutting the same surface.
It’s not a canned cycle that the program wrote up, but long form instead.
It begins with a G33 on the thread line followed by an "X" and a "Z" finishing with a "K" value.
Not sure if the OKUMA can accept anything but a canned cycle as this is new NX software and am working out a few bugs still. Any help would be much appreciated.
Thanks in advance.
