Here’s How to Write G Code for U Drill Drilling and Rough Boring

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.
