Help with okuma macro

[lowcountrycamo]

I would like to probe a diameter.  Save that diameter to a variable.  Then probe a z and subtract that z from half that diameter.  Basically I want to probe the top of a round and shift z to the center.  I use the easy set CALL O9023 macros and there is a shift var.  If is where Fanuc Macro B I understand that language somewhat.

 

thanks,

Is the sphere a constant diameter every time?

[Brad Lisle]

I can see a couple of issues here. First off you may not be probing on the outer tangency of the sphere, thus the radius measured will not be the true radius of said sphere. By shifting the measured radius you will not be in the true center of the sphere. If the sphere is always a known value, you could probe outside to find center, probe top, then probe outside again to center taking into consideration for the stylus radius.  Here is the code:

NPRB1
(ASSUMING X0. Y0. Z0. IS CENTER OF SPHERE)
(ASSUMING 1.0 SPHERICAL DIAMETER)
(ASSUMING 6MM STYLUS TIP)
T99 M06
G15 H1
G00 X0. Y0. M05
G56 HA Z2. M09
CALL O9832 (PROBE ON)
CALL O9810 PZ=.6 PF=100. (SAFE MOVE)
CALL O9814 PD=1. PZ=-.1181 (MEASURE BOSS DIAMETER)
VC1=VS75 (LOG MEASURED X POSITION)
VC2=VS76 (LOG MEASURED Y POSITION)
CALL O9810 PX=VC1 PY=VC2 (MOVE TO TRUE CENTER)
CALL O9811 PZ=.5 (MEASURE TOP OF SPHERE)
VC3=VS77 (LOG MEASURED Z POSITION)
CALL O9810 PX=VC1 PY=VC2 (MOVE TO TRUE CENTER)
CALL O9814 PD=1. PZ=-.1181 (MEASURE BOSS DIAMETER)
VC4=VS78 (LOG MEASURED DIAMETER)
CALL O9810 PZ=2. PF=300. (SAFE RETRACT)
CALL O9833 (PROBE OFF)
VC5=VC3-[VC4/2] (CALCULATE TO CENTER OF SPHERE)
G11 Z=VC5 (PARALLEL SHIFT OF COORDINATE SYSTEM)
M01

hello friends,
In the Fanuc system;
#3011 (YYYYMMDD)
#3012 (minute seconds to hour)
working as
I use #101=#3011 and #102=3012.

What is the equivalent and how should I define it?

Thanks in advance
