Process Description:
1. The cutter moves to the specified hole position (X, Y) in G00;
2. Moves down to the specified point R in G00;
3. Moves down to the point Z at the bottom of the hole in G01;
4. Retracts to point R in G01;
5. Retracts to initial point (G98) or point R (G99) in G00.

Command Format: G86 X_Y_Z_R_F_K_;
Description:
X_Y_: hole position data (absolute/incremental coordinate)
Z_: the position of point Z at the bottom of the hole (absolute programming); the distance from
point R to point Z at the bottom of the hole (incremental programming)
R_: the position of point R (absolute programming); the distance from the initial point to point R
(incremental programming)
