Start Spindle after Drill is in hole.

[Odin]

I am trying to figure out how to position gun drill inside of hole before coolant and spindle are turned on. How do I go about doing so? here is the code for the drill (chip break ) program. I want the spindle and coolant on at Z -1.0.

You would need a post modification to add a custom drill cycle.

 

Or you could just hand bomb the code like this:

I did not think pecking with a Gun Drill was recomended?

This is what I did for gundrilling:

 

prgunout	 #R drill position
 if cuttype = one, refht_a = refht$ + (rotdia$ / two)
 else, refht_a = refht$ + drl_prm1$
 refht_i = refht$ - initht$ + drl_prm1$
 if cuttype = three, refht_a = w$ + drl_prm1$
 if absinc$ = zero, refht_a, !refht_i
 else, refht_i, !refht_a
pgundrill		 #Canned Drill Cycle
 pdrlcommonb
 gunht = refht$ + drl_prm1$
 pxout, pyout, e$
 "G01", *refht$, "F75.", e$
 "G01", *gunht, "F6.", e$
 *scoolant, e$
 *speed, *spindle, e$
