1. BEFORE USE

1.1 Outline of Partial Step
Partial step beveling refers to the process to bevel a portion of the thick lens edge into a step to fit into frames so that only a part of the edge is inserted and protrusions are provided on the lens to hook into inden-tations in the frame groove.

These frames are mainly used as sport sunglasses. To use prescription sunglasses with these frames, the partial step is useful.

This manual describes the procedure from data cre-ation to lens processing for frames that need partial stepped lenses.

• For this Operator’s Manual, it is assumed that the Partial step license software has been already installed to the Ice 900 and Me 1200.

• Software version requires the following condition:Ice 900 Main: V1.03 or later

Me 1200 Main: V1.05 or later

2.1 Start up and Shut down of the Ice 900

For getting started and exiting the Ice 900, refer to “2.2 Getting Started and Exiting (Page45)” in the Ice 900 Operator’s Manual.

2.2 Data Saving, Loading, and Control of the Ice 900

For saving, loading, or control data of the Ice 900, refer to “2.3 Data Saving, Loading, Con-trol (Page 46 to 56)” in the Ice 900 Operator’s Manual.

OPERATING PROCEDURE: Creation of Partial Step (Ice 900)

2.3 Creation of Partial Step (Ice 900)

2.3.1 Preparation and measurement of demo lenses

1 Remove the demo lens from the frame and clean up the lens.When the part of the demo lens that is inserted into a frame groove is dirty, the measure-ment may not be performed properly.

2 After attaching the demo lens to the frame, mark the demo lens with a lensmeter.Refer to “2.6.3 Preparation for demo lenses (Page 99)” in the Ice 900 Operator’s Manual.

3 Roll out the specialized clay and adhere itto the rear surface of the demo lens alongthe frame.

1) If the specialized clay sticks to thenose pad, the specialized clay maynot come off easily. To prevent this,remove the nose pad before adheringthe specialized clay.

2) Leave a very tiny gap from the frameso that the specialized clay and framedo not touch. When adhering the spe-cialized clay, be sure not to squeeze itto the extent that it sticks to the frame.

3) The gap between the clay and edge is beveled with a step.

• Minimize the gap between the specialized clay and frame as much as possible, as it affectsthe accuracy of the DBL input.

• Keep the specialized clay from sticking to the frame, or entering the gap between the demolens and frame. If this occurs, when the demo lens is removed, the part of the specializedclay sticking to the frame may become stretched and desired step shape is not achieved.

• The shape may be detected by using a pen to trace the frame instead of specialized clay.However, detection of the trace data is lower quality than that for the specialized clay.

4 Adjust the gap between the specialized clay and edge for step beveling.

• Be sure that neither end of the specialized clay protrudes from the demo lens edge.• Should nose pad not be removed, or is non-removable, adhere the specialized clay around

it so that the step beveled lens and nose pad do not interfere with each other.

5 Remove the demo lens from the frame.Clean off any stains such as fingerprintson the lens, as they affect detection.

If the specialized clay sticks to the frameand is stretched out with the lensremoval, use the spatula to push the spe-cialized clay to the inner side so that thespecialized clay shadow becomessmooth when the lens is placed on theIce 900.

If the specialized clay sticks to the frameand is defomed along with the lensremoval, reform the shape with the spatula.

6 Display the Shape Imager screen on the Ice 900 and attach the lens table.Refer to “2.6.2 Attaching the lens table (for Shape Imager)” (Page 98) in the Ice 900 Operator’sManual.

• When measuring DBL with a caliper

When proper measurement of thenasal breadth is not possible, use acaliper to measure the outer distancebetween right and left nose pads.

The DBL value can be calculated as follows:

The DBL value is the outer distance measured with a caliper minus twiced the lengthdisplayed on the screen after measurement of either lens less the gap between thespecialized clay and the frame. (DBL = OD - 2 (L - gap))

2.3.2 Editing partial step beveling dataDisplay the Step screen to check the step data. When there is a gap between step data detected bythe shape imager and outline of the specialized clay, or when the step width and angle need to bechanged, the partial step data can be edited in this screen.

1 Press the Design tab then Step tab in the Layout screen to display the Step edit screen.

2 Press the button to display the over-lay of the camera image as shown in thefigure on the right as necessary.

After shape measurement, a still imageof the shape measurement is overlaid.

3 Edit the step data as necessary.

Setting step height

Specify the height of lens edges for stepbeveling.

1) Drag the handle at both ends of thearea to be faceted and specify the areato be faceted.

2) Drag the handle in the middle andspecify the step height.

Multiple fine alterations allow the step data to be precisely edited.

The four height numeric fields appear onlywhen the magnification is [x 1.0] and [x 1.5].

For details, refer to “● Setting step height”(Page 141) in the Me-1200 Operator’sManual.

Setting step width

Specify the width of lens edges for stepbeveling.

Press the Width numeric field to enter thestep width with the numeric keyboard.

Input range for width: [0.5 to 5.0 mm (0.1mm increments)]

Setting step angle

Specify the angle of lens edges for step beveling.

Press the Step angle numeric field toenter the step angle with the numerickeybord.

Input range for angle: [5 to 15° (1° incre-ments)]

2.3.3 Entering frame angle and curveWhen the frame angle and curve is forgotten to be entered, PD may not be correct after the processedlens is set to a frame. To correct the PD, enter a frame angle and curve.

1 Press the button in the Layout screen.

The Frame data edit screen is displayed.

2 Place a frame on the screen and enter theframe angle and curve.

1) Press the Angle numeric field to enterthe tilt angle with the tenkey pad.

(Angle 0.0° to 25.5°)

2) Measure a frame curve for the frontsurface of a demo lens. Press theCurve numeric field to enter the tileangle with the ten-key pad.

(Curve 0.0 to 12.0)

For details, refer to “Changing frame infor-mation” (Pages 73 and 74) in the Ice 900Operator’s Manual.

3 Perform blocking.For details, refer to “2.8 Blocking” (Page 127 to 132) in the Ice 900 Operator’s Manual.

• A lens to be blocked must have the same curve for the front lens surface as that of thedemo lens. If a lens with different curve for the front lens surface is blocked, the lens cannotbe set to the frame.

2.6 Creation of Partial Step (Me 1200)

The processing conditions such as lens material cannot be changed on the partial step data that hasbeen imported to the Me 1200. Specify the processing conditions on the Ice 900 in advance.When the layout values such as PD is imported with blank, the data can be input on the Me 1200.However, the layout values that are input on the Ice 900 cannot be changed on the Me 1200.

2.6.1 Importing shape data and processing with the Me 1200

1 Import blocked data from the Ice 900.For details, refer to “2.4 Importing Shape Data” (Page 56 to 59) in the Me 1200 Operator’s Manual.

1) Press the shape data No. button ofthe Me 1200 which is in standbymode (not during processing) to dis-play the keyboard screen.

2) Enter the JOB code specified in the

Ice 900 and press the but-

ton.

When the barcode scanner is used, loadthe JOB code with the barcode scanner.

The request for data transfer is sent to theIce 900. The Ice 900 which received therequest sends data corresponding to theJOB code to the Me 1200.

• The lock of the partial step data that has been imported to the Me 1200 can be released bypressing the Layout lock button. However, the mode is switched to the Step beveling modeand the partial step beveling is be performed.

When the lock is released, the processing image is changed to the nor-mal step beveling image shown in the picture to the right.

2 Check the layout and set the lens.

To set the lens to the lens adapter, refer to “2.7 Flat (rimless) Edging” (Page 76 and 77) inthe Me 1200 Operator’s Manual.

3 Press the button and start the partial step beveling.

• A lens to be blocked must have the same curve for the front lens surface as that of thedemo lens. If a lens with different curve for the front lens surface is blocked, the lens cannotbe set to the frame.

• Partial step beveling is a flat edging without safety beveling and polishing. Processing suchas safety beveling may need to be performed by hand depending on the groove shape ofthe frame.

• Where the lens edge is thicker than the length of the drill, design cut cannot be performed.
