ours in the XY plane
Circular slot in XY plane
You can find the reference dimension ZR and the limit diameter IR
with the "select reference plane" function (see page 418).
ICP generates:
 The section code FRONT_Y with the parameters limit diameter,
reference dimension and spindle angle. The section code is omitted
for nested contours.
 A G308 with the parameters contour name and milling depth.
 A G372 or G373 with the parameters of the figure.
 A G309.
