Could someone explain when you would use fixture offsets with a lathe?

TIA

I have used work / fixture offsets to machine more than one part on the lathe when the gcode is for only one part.
IE; G54 for the first one and G55 for the second one. The G55 just has a modified Z work offset compared to the G54 Z offset so it's start where the first part was parted off. Now if some reason, say a diameter was off you could also use another work offset to change X work offset by some amount to tweak the final machining. Just need to use your imagination.

BTW, I use a custom screen and can select / change the work offsets at will for any amount desired without leaving the current page.

Ok thanks Rich, that makes sense.  Do you just put the g5x.x in your code?  As you can tell I'm not a machinist but working hard to learn as much as I can.  Your willingness to share your knowledge is greatly appreciated.

You could put it in the code.
 Again, I easily alter one of the work offsets and set it current via the screen. Then rerun the program from home position.  Since I don't use switches, my lathe is always set such that home is
referenced location ( Machine Coordinate 0,0), there is no work offset defined in the gcode of the program, and there are no work / fixture offsets on startup. G54 work offset is created when touching off the stock. To each their owe on how they work and that includes me.
