ours in the YZ plane
Single surface in YZ plane
This function defines a surface in the YZ plane.
You can switch between depth (Ki) and residual depth (K) by pressing
a soft key (see table at right).
You can find the reference diameter XR with the "select reference
plane" function (see page 418).
ICP generates:
 The section code SURFACE_Y with the reference diameter and
spindle angle. The section code is omitted for nested contours.
 A G308 with the parameter contour name.
 A G386 with the parameters of the single surface.
 A G309.
Soft key
Switches the field to entering the
residual depth K.
