Custom Drill Cycle to Change Speed

[Brian B 74]

Hi All!

 

Does anyone have some code I can borrow to develop a custom drill cycle for our Fanuc control?  I am looking at using a drill 30xD (OSG Helios) and it says to drill a pilot hole about 2xD.  On a low RPM get the Helios drill into the hole.  Turn up the rpm to the recommended SFM and drill the hole.  Then feed back up - slow the rpm and exit the hole.

 

Can anyone help me with this?  I was thinking maybe a Custom Macro, but MCX code would be best.

 

Thanks!
