Barfeed after barpull with sub

[thierry924K4]

Hi everyone

I got a piece and I am kinda stuck with it.

I do a barpull the do some more work and part off then i barfeed but I cannot figure out whzt the barfeef distance would be...

I start 25mm out of the chuck

Then 1mm cut to smooth the front

Then subspindle comes and moves 7mm over the part And grabs part

Then I move out 67mm (workpiece is 75mm (67 + 1mm of smoothing + 7mm of spindle grab)

Then some more lathe work and part of

Then i want to barfeed, i would say i should be 78.11mm (cuting tool is 3.11mm)

But it does not seem to work... i does not get back to 25mm...

okay, what does it go to? And what machine are you using, and how are you using Fusion to program your bar pull?

First time went to 26mm and then i proceeded the job (cut of 2mm at once)

2e time it went to 50mm out of the spindle...

Spindlereturn - keep both spindles closed and offset to 67mm
Then another spindle return to zero
