- In this video, Marc from @GCodeTutor shows us how to write a sequence of G-Code to both drill and rough bore using a U-Drill.
Marc starts off by writing the G-Code that sets our machine in a safe working state before moving on to the drilling section. When drilling with a U-drill, we write the G-code as we would for a standard point-to-point drilling operation without using cycles. Once the hole has been drilled, we can then offset the U-drill to use it as we would a boring bar.
Marc talks about the calculations we need to do to work out the offset amount to produce a bore with a finishing allowance for a later finish bore operation.
To complete this sequence, we then finish writing the rest of the G-code to return our tool to a safe place, ready for the next tool change.

Very good video. One trick i'd like to add which makes using a udrill as a boring bar more useful is calling up a second tool offset for boring. For example, touching off T0929 like you would a boring bar on x/z so you can dial in size with wear.
Nice vid, what are the down side of using a udrill as a boring bar? Have to take light cuts? Not a lot of choice of insert geometry?
Limited Insert types, increased wear on 1 tool, you need to be very careful how much you leave on z faces if youre finishing with it (They don't have the clearance/relief to take more than a couple thou) if you need a square corner or perfectly flat hole bottom the geometry may not allow it. And sometimes chip packing on the first boring pass can be an issue.
@@thehollowbox Thanks, got a job coming up where i want to try it
@@lawmate Do you program by hand or through cam? Just make sure when you're boring the clearance/X retract on the first pass is set up right. We've accidentally run the back of the tool against the bore a couple times.
8 minutes of wasting time
and finish pass in the next video is genius
also where can I buy a drill from your screen?
and this drill will not work on CW rotation
Omg I love all the videos you put up! Keep up the good work!
