lathe programming with multiple reference part positions

Hi fellow users,



I'm trying to figure out the best method for programming a lathe part
that changes position in the machine several times though use of
position transfers utilizing the sub-spindle.



Are people programming a single part/work-piece assembly in space?



Or, are people constructing an assembly of their machine and assembling
several instances of the same part in the different positions in which
it will be machined? This gets messy, particularly when the positions
overlap.



I've started out with multiple parts as I am familiar with when doing
tombstone fixturing on a machining center but feel I may need to switch
gears for this lathe stuff. I've been handling the transfers and zero
shifts with CL-commands that pass relation driven parameters to custom
macros in the post. I guess I could still do this if I program a single
part/work-piece assembly in space but would have to approach it
differently.



How are others doing this?



Thanks
