Circular pattern on lateral surface G412 Geo
G412 defines a circular pattern on the lateral surface. G412 is effective
for the bore hole/figure defined in the following block (G310..315, 317).
Programming notes
■ Program the hole/figure in the following block without a center –
exception: circular slot.
■ The milling cycle (MACHINING section) calls the hole/figure in the
following block - not the pattern definition.
Parameters
Q:
Number of figures
K: Diameter of circle
A, W: Starting angle, end angle – position of first/last figure (reference:
Z-axis) – default: A=0°; W=360°
Wi: Distance between two figures
V: Direction (orientation) – default: 0
■ V=0 – without W: Distribution over complete circle
■ V=0 – with W: Distribution over long arc
■ V=0 – with Wi: Algebraic sign of Wi defines the direction
(Wi<0: Pattern in clockwise direction)
■ V=1 – with W: Pattern in clockwise direction
■ V=1 – with Wi: Pattern in clockwise direction (algebraic sign of
Wi is without meaning)
■ V=2 – with W: Pattern counterclockwise
■ V=2 – with Wi: Pattern counterclockwise (algebraic sign of Wi
has no effect)
Z, C: Position, angle to midpoint of pattern
H:
Position of figures – default: 0
■ H=0: Normal position – figure is rotated about the circle center
(rotation)
■ H=1: Original position – position of figure remains the
unchanged with respect to the coordinate system (translation)
