HEIDENHAIN CNC Pilot 4290 Description of the Y axis - Manual (Page 6)

Y Axis 6
2.1 Section Codes,
Overlapping Contours
FRONT_Y, REAR SIDE_Y
The section code identifies the XY plane (G17) and
the reference plane of the contour (Z direction).
Parameters
X: Area diameter (as cutting limit)
Z: Position of the reference plane – default: 0
C: Spindle position – default: 0

Start pocket/island G308
G308 defines a ”new” reference plane / reference diameter in
hierarchically nested contours (see also Chapter 2, ”Y Axis in DIN
PLUS”).
Parameters
P: Depth/height
■ P<0: Pocket
■ P>0: Island
End pocket/island G309 Geo
G309 ends a reference level. Every reference plane defined with
G308 must be ended with G309!
