On XYZ axes simultaneously cleared: G54P * (except 1,2,3,4,for any value , not fill P also)
G81: (drill instruction)
Format: G81X .. Y.. Z.. R.. F..
X.Y represent end coordinates, Z represents the depth of machining F processing speed
R represent operating plane (safe altitude) at the beginning, represent and Z Terminal point after returned
Case: (coordinates (20.0), (20.20), (0.20), (0,0) four drill holes 5mm in depth, the two safety plane, a speed of 200)

X, Y represent Terminal point coordinates,Z represents the depth of machining, S represents dwell time at the hole bottom.
F processing speed
R represent theoperating plane of the beginning,and represent Z terminal point after returned.
