All,
I'm working on changing up a drill cycle for tubing. I'd like a G81 cycle that drills through one side of the part, then feeds/rapids through the middle of the part which is open, then feed through the far side of the part. Is anything like this possible?

There is . It is called a web cycle. . It is designed to do what you are asking for. If my memory serves me correctly it is a g85. Let me check it out .

The only option is to remove the cycle completely, and manually program the drilling path longhand
- use "drill point" ( to get the required tool into the spindle), and then insert the follow code into a "Manual Input" ( you may have to do a minor edit in the NC code )
ie
G0 Z.1
G1 Z-.2 F3. ( 1st wall)
G1 Z-.5 F10.( fast feed thru middle )
G1 Z-.7 F.3 ( other wall)
G1 Z.1 F10. ( faster feed to allow swarf to be drawn off the tool )
G0 Z.5
