4.6 C-Axis Contours—Fundamentals
Start pocket/island G308-Geo
G308 defines a new reference plane / reference diameter in
hierarchically nested contours.
End of pocket/island G309-Geo
G309 defines the end of a reference plane. Every reference plane
defined with G308 must be ended with G309 (see “Milling contour
position” on page 202).
Example for G308/G309
Parameters
P Depth for pocket, height for islands
ID Name of the contour for reference from units or cycles
