I'm not super savvy with lathes so forgive me if I'm overlooking something obvious.
New machine to me, Murata/Warner Swasey WSC6 with Fanuc 0T (not sure which version) and all jaws and parts are programmed offline in CAM.
This machine uses work shift and does not have work offsets like on other lathes I have run. Since I have to pick one zero point and stick with it I would like to use the face of the chuck. This seems easiest to me for quick changeover of parts. For example if I put in a set of 1.5" thick pie jaws that need to be faced I could just add 1.5" to the work shift, or better yet use the face of the chuck as my zero point in CAM with my jaws modeled 1.5" thick. Is that how the work shift function is meant to be used?
When I go to set my first OD tool T0101 I jog in Z up to the chuck and back it off while I roll a 1/2" dowel pin around until it slips through. This should put my tool at Z0.5". On the control in the offset/geometry page I enter M, Z, 0.5, input and get T0101 Z =-0.5". This seems like it could be right so far, though I kind of expected some arbitrary number, but again not sure how the work shift function might change things.
I repeat this for a boring bar that is a very different length and end up with T0202 Z =-0.5". This does not seem right any more, as this part that is about 1" longer should show up as 1" different length in the offset/geometry page.
It took me going down a YouTube rabbit hole to figure out that pressing M before the axis meant measure, so it is highly likely that I am missing some other step, but its also likely I'm going about this process completely wrong.
Any advice on this would be much appreciated, this machine has been sitting idle while I manage other projects but I finally have enough work that it seems worth figuring it out.
