Parameters
ID Drilling contour—Name of the hole definition
NS Block number of contour
Reference to the contour of the hole (G49-Geo, G300-Geo
or G310-Geo)
No input: Single hole without contour description
XS Starting point of axial hole (diameter value)—Single hole

F Thread pitch (prevails over the contour description)
B Slop.length (run-in length)
S Return speed (default: Tapping speed)
J Retraction length when using floating tap holders (default: 0)
RB Return plane (radial holes: diameter) – (default: retraction to
starting position or to safety clearance)

BE End element no. (number of the last hole to be machined in a
pattern)
H (Spindle) Brake off (default: 0)
