HEIDENHAIN CNC PILOT 4290 101
Circular pattern on front/rear face G402 Geo
G402 is effective for the bore hole/figure defined in the following block
(G300..305, G307).
Programming notes
■ Program the hole/figure in the following block without a center. –
Exception circular slot: the ”center of curvature I, J” is added to
the sample position (see ”
4.5.8 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 figures
K: Pattern diameter
A: Starting angle – position of the first figure (reference: XK axis) –
default: 0°
W: Ending angle – position of the last figure (reference: XK axis) –
default: 360°
Wi: Angle between 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: clockwise)
■ V=1 – with W: clockwise
■ V=1 – with Wi: clockwise (sign of Wi has no meaning)
■ V=2 – with W: counterclockwise
■ V=2 – with Wi: counterclockwise (sign of Wi has no meaning)
XK,YK: Center in Cartesian coordinates
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).
