Inputting a tilting amount
The bevel position has been moved backward in Step though the upper part of the edge is
thick. Move the bevel forward by inputting a minus value to “TILT”. In doing so, always
observe the bevel on the boundary between the distance and near parts. In most cases, the
edge’s thinnest point is on the boundary. Adjust the tilting amount within a range that at least a
bevel on either the front or rear side remains.
See the following in adjusting the bevel position at each point. To reset all the settings, reset
“TILT” and “PNT” to 0.0, and put “A (automatically-calculated curve value)” at the head of the
curve value. This will allow an operator to reset the bevel position and tilting amount from the
beginning.
Position adjacent to the point straight down
from the frame center (Tilt base position)
• If the lens edge is thin, change the bevel tip
point (PNT) to move the bevel backward as
much as possible.
• If the lens has enough width, place the bevel
tip point at 1/3 from the rear surface of the
edge.
• Do not input the tilting amount, and leave
“TILT” 0.0.
Upper position (diagonally-opposite point to
the tilt base point)
• Move the bevel position forward as much
as possible in the range that the bevel on the
edge’s thinnest point remains on the edge.
• Increase the tilting amount (TILT) in the
minus direction to tilt the bevel toward the
front surface.
Edge’s thinnest position (on the boundary
between the distance part and near part)
• Move the bevel position on the upper part
forward, observing that the bevel tip point
at the edge’s thinnest point remains on the
edge.
• Set such a tilting amount (TILT) so that the
tip of the bevel barely remains.
