How do I make G94 appear in tap mode but not in drill cycle?

[PcRobotic]

Hi,

I have problems with pitch tap which must have G93 to starts cyle and ends with G94. Please see below these dotted lines

Hi PcRobotic,

 

You will have to force the string sgfeed, for tapping operations only (drillcyc$ = 3), in the post block pcanceldc$ right before the G80 output.

 

if drillcyc$ = 3, pbld, n$, *sgfeed, e$

if drillcyc$ <> 8, pcan1, pbld, n$, "G80", scoolant, strcantext, e$

 

sgfeed is the target string for a string select table, so it will only output G94 if the selector variable, ipr_type, is set properly.

 

Hope this helps.

Since 'sgfeed' is a string select variable, the output will depend on the value of 'ipr_type'. Instead of 'sgfeed', I would use 'sg94' in it's place. That way you are always forcing "G94" explicitly.

Thank you Ivan, it works.
