Circular pattern on end face G402-Geo

G402 defines a circular pattern on the front/rear end face. G402 is
effective for the 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 milling cycle (MACHINING section) calls the hole/figure in the

following block - not the pattern definition.

Parameters
Q:

Number of figures

Pattern diameter

A, W: Starting angle, end angle – position of first/last figure (reference:

XK-axis) – default: A=0°; W=360°

Wi:

Angle between two figures

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)

XK,YK: 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 the

unchanged with respect to the coordinate system (translation)
