G845 – calculating hole positions
G845 A1 .. calculates the hole positions and stores them at
the reference specified in NF. The cycle takes the diameter of
the active tool into account when calculating the hole positions.
Therefore, you need to insert the drill before calling G845 A1...
Program only the parameters given in the following table.

Further information:
Parameters:
ID: Milling contour – name of the milling contour
NS: Starting block no. of contour – beginning of contour
section
Figures: Block number of the figure
Free closed contour: First contour element (not starting
point)
B: Milling depth (default: hole depth from the contour definition)
XS: Millg. top edge lateral surface (replaces the reference plane
from the contour definition)
ZS: Millg. top edge face (replaces the reference plane from the
contour definition)
I: O-size X
K: O-size Z
Q: Mach. direction (default: 0)
0: From the inside out
1: From the outside in
A: (Mill=0/PredrillPos=1)
NF: Position mark – reference at which the cycle stores the
hole positions (range: 1 to 127)
WB: Plunging length – diameter of the milling cutter
G845 overwrites any hole positions that may still be
stored at the reference NF
The parameter WB is used both for calculating the
hole positions and for milling. When calculating the
hole positions, WB describes the diameter of the
milling cutter.
