Getting to know The Money Pit a little and this control uses a G93 to cancel G92 presets.
So I start thinking .... ... Is this common? I don't recall seeing something like this before, but in all honesty - milling isn't the bulk of my work, and the milling controls that I have are all flavours, and so most of my experience dates back to the A900 Cinci. I used to use G92 on that regularly, but not since untill now.
But G93 there as it seems is "Inverse Time" feedrate.
Not just a few months ago we was discussing this over in the Haas board regarding feedrate for the rotary axis. It was all new to me and I thought that it was a Haas specific code from the sounds of it. I guess it long pre-dates Haas Manufacturing - and likely dates back into the NC controls. ??? I would have had no need for such code for the 2-1/2 axis werk that I did on that machine. So no wonder it didn't ring no bells.
ANY WHOOOO
I am using G92 quite a bit on The Money Pit, and it is quite helpfull to be able to just G93 and go back to "Machine Zero" as it would be. Now one thing that I am NOT liking quite as much is that G93 is a blanket and ALL axis go back. NOT just a singular axis like the G92 code does, but I think we can change the code on that if wanted.
Now of course you can git the same place by using fixture offsets and cancelling them as well.... But you need one fixture offset set to ZERO don't you?
On my Siemens machines I can just code in G500 (I think) which is essentially always set to zero - or close to it. On a PC control I can call E0 and cancel all fixture offsets. I'm not sure on my Mits, but on a lathe that's not nearly as applicable anyway...
I doo not have a Fanuc mill, but I hafta wonder - if you don't have G54 set to zero, what means is there to dump the offset altogether w/o just replacing it with another?
