G85. Reaming canned cycle
9.11.1 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. Movement at the working feedrate (G01) of the longitudinal axis to the bottom of the machined
hole, and reaming.
4. Dwell, if parameter "K" has been programmed.
5. Withdrawal at working feedrate, of the longitudinal axis as far as the reference plane.
6. Withdrawal, at rapid feedrate (G00), of the longitudinal axis as far as the initial plane if G98 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:
