I've offered to make some bronze bearings for a vintage British
motorbike club.
The bearings have some helical oil grooves on one half of the inner
diameter.
I thought I could do this with G76 having the pitch twice the length of
the bush.
G0 X15. Z10.
G76 P42.0 Z-25. I0.88 J0.3 K1.0 Q29.5 H1 L0 R1.5
The problem is that the spindle, run via a VFD needs to turn at only 50
RPM to be able to have enough velocity on the Z stepper to achieve the
correct pitch and the spindle doesn't seem to be stable enough or have
enough torque at those revs to give a cosistent cut.
Does anybody have any ideas how I can check or make the G76 more stable
at low revs?
Thanks,
Pete
