The CNC sets up the cycle. This is the
only time that the CNC initializes the
variables for this cycle.
CNC advances the slide, and then it begins
and completes the boring operation.
CNC moves the the slide to the return
position.
The CNC checks its position.
The CNC sets modal G-codes.
CNC moves the tool to the tool change
position and then ends the cycle.
