To do circular interpolation on my Cincinnatti I would put in say G0 X3.0 Y0.0 Z0.0 then G0 X3.0 Y0.0 Z-1.0 I0.0 J0.0 K.1 F25.0 and I would bore a hole 6" in dia. and 1" deep. That does not work with a Yasnac/Tree and the book is real close to being worthless. Also on my Cincinnatti if I put in a tool length and tell it M6 T1 then G0 Z0.0 it will go there, pretty simple. I have tried every thing I can think of after a tool length measurement and doing a Z 0.0 just makes the head go up to the machine 0 Its enough to drive me to drink and its begining to look like a short drive. Maybe there is a clearer book

G13I.4K.88D22Q.38F20. will do a 1.76 dia start hole ending at a 2.8 dia with .38 stepover using cutter comp number 22 with feed of 20 IPM

I=finish circle radius. K=start circle radius.D= cutter comp offset.Q=stepover.
Program to desired z depth then do g13.
Then program z back up to reference plane.
