Linked or Grouped Offsets?

[danrudolph]

I have a job where I have to blend three tools precisely, a front turn, thread tool and a groove tool used to clean up the thread.

I am able to get the blends perfect, but I would like to be able to then shift the X of all three tools as a group. Offsets are T03, T04 and T05. I would like to use say, T10 to adjust T03, T04 and T05 at the same time.

Is there a way to do this on a Citizen A20?

I did a little research on this idea, here's what I came up with:

In the program I could write the following at the start:

#2003=[#2003+#2010] (T03 Line)
#2004=[#2004+#2010] (T04 Line)
#2005=[#2005+#2010] (T05 Line)

Then by adjusting the X value of offset T10, the relative changes would be transfered to each of the three tool offsets at the start of the cycle.

Where #2003 is the X value of the T03 offset and so on. I am not sure if Citizen is using the tool wear offsets or the geometry offsets on its single offset page? If so, those variable numbers may be different.

If anyone has a better implementation, I am all ears...

The issue with this implementation is that (I think) you would be accumulating the #2010 offest with each read, as each time you're reusing #2003/4/5 which already has #2010 added to it from the previous read.
A different implementation would be to use a G50 U-#2010 to apply the value of T10 Xoffset as a shift to the X axis then cancel by G50 U#2010.

Good luck.
