16) BF ChuckLayout Height : ± mm
Factory setting: + 5 [mm]
This is for setting the lens layout for blocking lenses. Specify the shifted values from the
top line center of the segment in blocking bifocal lenses. When using the NIDEK Cen-
tering device, Model CE-1, leave the setting at the factory setting (5 mm outside, 5 mm
up) and never change it.
17) TILT Function : None, Exec
Factory setting: None
This is for selecting whether or not to use the tilting function in the guided edging mode.
If a lens has an extreme difference in width between the edge’s thickest point and thin-
nest point, the appearance of the mounted lenses will improve by tilting the bevel.
18) Reverse GLS Grind : None, Exec
Factory setting: None
This is for selecting whether or not to use the roughing function which changes the lens
rotation direction to reduce the processing time of a glass lens. To put a premium on the
processing time reduction, set this parameter to “Exec”. Setting this parameter to “Exec”
roughly edges a lens by automatically changing the position to be contacted with the wheel
from side to side so that the roughing wheel will not be worn on one side.
19) Grinding mode : STD, Soft
Factory setting: STD
This is for selecting whether or not to turn on the soft processing mode as default. See
“4.5.3.5 Soft processing” (p. 4-51). If this parameter is set to “Soft”, the soft processing
mode is automatically turned on when “PLA”, “HPL”, “PC”, or “GLS” is selected for
the lens material. In this mode, the processing sound and the axis shift of a lens whose
coating is smooth are reduced. For glass lenses, this mode is effective to prevent lenses
from breaking during processing.
20) Meas. after roughing : None, All, PLA
Factory setting: None
This is the setting of the function that allows remeasurement of lens shape after roughing.
None: After roughing, the lens shape is not remeasured.
All: Except when the lens material is set to “GLS” (glass), the lens shape is remeasured
after roughing.
PLA: When the lens material is set to “PLA” (plastic) or “HPL” (high-index plastic), the
lens shape is remeasured after roughing.
Remeasuring the lens shape after roughing prolongs the processing time; however, the
problem that a bevel or groove is displaced from the desired position due to distortion
produced on a lens during roughing can be improved.
Regardless of this setting, the lens shape will not be measured when both the “Measure
in flat edge” parameter and the “To add safety bevel” parameter are set to “None”, and
neither chamfering nor grooving is performed in flat edging.
