Circular pattern YZ plane G482 Geo
G482 defines a circular pattern in the YZ plane. G482 affects the
figure defined in the following block (G380..385, G387).
Programming notes
■ Program the hole/figure in the following block without a center –
exception: Circular slot. If you program the ”center of curvature
X, Y” of a circle, it is added to the pattern position (see User's Ma-
nual, section 4.7.9 ”Circular Pattern with Circular Slots”).
■ The milling cycle (MACHINING section) calls the hole/figure in the
following block - not the pattern definition.
Parameters
Q: Number of holes - default: 1
K: Pattern diameter
A: Starting angle – position of the first figure (reference: positi-
ve Z axis) – default: 0°
W: Ending angle – position of the last figure (reference: positi-
ve Z axis) – default: 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 has no effect)
■ V=2 – with W: Pattern counterclockwise
■ V=2 – with Wi: Pattern counterclockwise (algebraic sign of
Wi has no effect)
Y, Z: Center of pattern
H: Position of figures – default: 0
■ H=0: Normal position – figures are rotated about the
circle center (rotation).
■ H=1: Original position – position of figure remains
unchanged with respect to coordinate system (translation).
