3 * R – retract position along the Z axis;
4 * Q – delta increment along the Z axis;
5 * L – repeat count.

7 The (% style="color:#a0be2d" %)//**G73 **//(%%)cycle is drilling or milling with chip breaking. This cycle takes a Q number which represents a delta increment along the Z axis.

9 1. Preliminary motion:
10 If the current Z position is below the R position, The Z axis does a rapid move to the R position.
11 Move to the X Y coordinates.
12 1. Move the Z-axis only at the current feed rate downward by delta or to the Z position, whichever is less deep.
13 1. Rapid up a bit.
14 1. Repeat steps 2 and 3 until the Z position is reached at step 2.
15 1. The Z axis does a rapid move to the R position.
