G81. Drilling canned cycle
9.7.1 Basic operation
1. If the spindle was previously running, it maintains the turning direction. If it was not in movement,
it will start by turning clockwise (M03).
2. Rapid movement of the longitudinal axis from the initial plane to the reference plane.
3. Drill the hole. Movement of the longitudinal axis at work feedrate, to the bottom of the hole
programmed in "I".
4. Dwell K, in hundredths of a second, if it has been programmed.
5. Withdrawal at rapid feedrate (G00) of the longitudinal axis to the initial or reference plane,
depending on whether G98 or G99 has been programmed.
Programming example assuming that the work plane is formed by the X and Y axes, that the Z axis
is the longitudinal axis and that the starting point is X0 Y0 Z0:
