Tsugami swiss-type lathe
Mfg'd ca. 2000
Tsugami BS12(B)III with collet/bushing chuck
Fanuc 180is-TA control
Windows-based, touchscreen interface
Having problems with parts coming out incorrectly: tool is not cutting consistently. Possibly worn gibs or something similar? Have been hacking programs to compensate with relative moves, but discrepancies just get worse each time.
Original code (worked until recently):
Current code, hacked to compensate for discrepancies in size/profile:
Attached picture:
I think the two issues are linked. Thoughts?

- Bottom: nose as turned. Should be spherical nose, instead radius incorrect, and scallop at radius-taper intersect
- Top: nose and taper as milled. Flute milling operation leaves a ridge in the flute, which started about the same time as the turning issue did.
I think the two issues are linked. Thoughts?
