Just in the process of writing a macro to check the concentricity of two ends of a part on a horizontal machining centre.

The first end is probed to check if a bore diameter is in tolerance, then it probes the OD of the part, indexes 180deg and probes the other end.

I haven't proved my macro yet, but I think the following would work. The only thing I wanted to do, and this is my question, was have another alarm generated when BOTH X and Y are out of tolerance. What would be the best way of doing this? Would I have to use some kind of counter?

Thanks in advance!


(G65P9814D50.Z-10.H0.1) (PROBE DIAMETER AND CHECK IF IN TOLERANCE)

(G65P9814D80.Z-10.) (PROBE DIA FOR REF CONCENTRICITY)


#605 = ABS[#135] (STORE X VALUE OF CONCENTRICITY REF DIA)
#606 = ABS[#136] (STORE Y VALUE OF CONCENTRICITY REF DIA)



IF [[ABS[[ABS[#135]]-40.]] GT 0.025] GOTO 1003

IF [[ABS[[ABS[#136]]-40.]] GT 0.025] GOTO 1004




GOTO1212

N1002#3000=101(TARGET DIAMETER INCORRECT)
N1003#3000=102(X POSITION FOR CONCENTRICITY OUT OF TOLERANCE)
N1004#3000=103(Y POSITION FOR CONCENTRICITY OUT OF TOLERANCE)

N1212M00

Hi Alexmf,
this is how I would do it:

IF [[ABS[[ABS[#135]]-40.]] GT 0.025]THEN#135=1 (IF #135=1 THEN X OUT OF TOL.)
IF [[ABS[[ABS[#136]]-40.]] GT 0.025]THEN#136=1 (IF #136=1 THEN Y OUT OF TOL.)

(OR THIS IF YOUR CONTROL DOESN'T SUPPORT "THEN")

IF [[ABS[[ABS[#135]]-40.]] LT 0.025]GOTO1
#135=1 (IF #135=1 THEN X OUT OF TOL.)
N1
IF [[ABS[[ABS[#136]]-40.]] LT 0.025]GOTO2
#136=1 (IF #136=1 THEN Y OUT OF TOL.)
N2

#137=[#135+#136](IF #137=2 X AND Y OUT OF TOL.)

(ERROR CHECKING)
IF [#137 EQ 2] GOTO 1005
IF [#135 EQ 1] GOTO 1003
IF [#136 EQ 1] GOTO 1004


N1002#3000=101(TARGET DIAMETER INCORRECT)
N1003#3000=102(X POSITION FOR CONCENTRICITY OUT OF TOLERANCE)
N1004#3000=103(Y POSITION FOR CONCENTRICITY OUT OF TOLERANCE)
N1005#3000=104(X AND Y POSITION FOR CONCENTRICITY OUT OF TOLERANCE)



the check for both is tested first which allows all possibilities, Hope this helps

Cheers for that Mark! All worked fined apart from on the next run it as alarming out on X AXIS OUT OF POS, but after scratching my head for a while, realised the #135, #136 and #137 variables needed resetting to zero again.

Cheers for your help!

Alex.

Hi Alex,
That makes sense, Nice to see you worked it out.
