Mazak FH 8800: calculations for new work offset based on a relative work offset

Hi all

We have 4 axis FH 8800 Mazak machine with B as a rotary axis. I have noticed that the machine able to assign a new work offset coordinate based on another existing work offset. For example, take the same Y value of G54 for G55 and changing B, X, and Z values based on calculations only without any probing or measurements

The code will be for example:

G65 P9003 M8800 A54 B55 D0.0 E-90.0 X-7.00 Y0.0 Z8.00

Then select B value #5304

my question is what does that feature mean? Is it a dynamic work offset feature?
Can we have a similar feature for the Fanuc control system?

Thanks,
 
G65 is a macro call. O9003 is the macro program being called. It's most likely hidden, but can be unlocked via parameter.
All the logic for calculating the new coordinates is in O9003. All the variables in the G65 call are used by the macro to do the calculations and assign values to a new WCS.

You can use the logic in O9003 on a Fanuc system but the syntax may be different.
