Horizontal Drilling using G81

Hello,

I am currently trying to used the canned drill cycle to perform horizontal drilling using the drill head of my router (attached). As can be seen, four horizontal drills are available, however I have been able to use only two so far, i.e. only where R > Z. Drilling on the planes facing -Y and -X is proving impossible without rotating the coordinate system, which on the other hand is quite difficult to automate on CAM.

Any ideas?? Thanks

Terence

Hi!

Thank you for your reply

Yes you can put it like that. I am trying to do 'upside down' drilling in the G18(XZ) plane and G19(YZ) plane. Hence when the ngc file is loaded I am given the error that R is less than Z.

Using G0 and G1 is one possible solution, but the CAM I use outputs G81. Not to mention canned cycles are surely convenient.

The machine IS configured in a normal way....drilling in the Z axis is normal. But for side drilling it has horizontal drills mounted opposite each other (refer to photo above). Is there a way to bypass the R<Z error in the G81 canned cycle?
