Material

A table will exist for each material defined in the system Each will have the following items available for lab definitions. Additional processing set up is located in the Account Material Configuration file.

Note: There will be many occurrences of Account Material Configuration setups, one for each defined material.

Tool Rnd

Enter what you want tools to be round to (ex: 0.125 or 8)

Rounding increments for laps in use for the material. Typical answers are 0.1000 or 0.1250

Verify the rounding increments used by the lab by inspection or review with the managers. Expect to see ending values printed on the laps like #25, #12 or #10. The ending digits are the key to determining the rounding. If there are laps ending in #25 or #12 the rounding is in 1/8^th, while those ending in #10 are in 1/10^ths. 1/8^th diopter in decimal format equals .125 increments, and 1/10^th diopter in decimal is .100 increments.

There is only one setting per material. Any lab running mixed sets, both in 1/8^th and 1/10^th will need to choose one rounding method.

Tool DP

Enter number of digits to print after the decimal place for tools

Number of positions to the RIGHT of the decimal point when printing the tool (lap) and curve data on the work ticket.

Prism Index

Enter index that prism rings/blocker are at, or 0.0 to match material

Prism index for calculations. By default this should equal the material index.

Note: Watch for differences if similar settings are available in the generator. The system and generator files should match.

Prism index may require entry of an actual index. The two primary cases are: If the lab uses AutoFlow blockers and/or if the lab has need of old style prism rings.

Tool Index

Enter index that tools are cut for (0.0 to match the normal 1.530)

Index in which the laps are cut and index of the gauges in use. Default is 1.530.

Note: If the field has 0.0000 the default of 1.530 is in use.

Surface Rm

Enter amount of surface removal from fining and polishing

The term “Surface Rm” means Surface Removal. This is the amount of material loss during the fining and polishing process.

Enter Y to print markup prism axis 0-360 degree, N to print -180 to +180

Set to (N) for typical 0-180 angles, and to (Y) for 0-360 angles. Applies to prism angles only.

For use with LOH blockers that block prism and use the 0 to 360 degree scales. This is also the setting for the prism angle printed on the work ticket and the angle sent to the generator to cut prism.

Enter Y to default to center blocking most lenses, N to MRP block

Set to (Y) for geometric layout of lenses in surfacing. If (N) then MRP Blocking is active by default.

Note: Some lenses such as Aspheric or Progressive may have unique blocking settings from the Special Lens Type file. Those settings will override or use this setting (Center Blk) to determine layout.

Enter Y to be prompted to enter blank center thickness

If set to (Y) the system will prompt the entry operator for the center thickness of the lens blank. The prompt for center thickness is only displayed on a sag entry lens.

Enter Y to print resolved prism on wk ticket when Rx prism not resolved

If (Y) will print the resultant prism (from prescribed prism data) and the resulting prism angle.

The following groups of Psm Lmt #, Psm Rnd # and Psm DP # are for use with prism blockers and/or prism rings. It will define the ranges and rounding increments for the ring sets. If prism is always ground in the generator, the limit in Psm Lmt 1, should be set to 99.00, the rounding to 0.01 and the decimal point (DP) to 2.

Enter upper prism limit 1. Prism <= limit will be rounded/printed per below

Maximum prism for the first set of rings.

If the lab does not block prism, nor uses prism rings then the value for Psm Lmt 1 should be set to 99.0. The values in lmt 2-5 will not be active regardless of their setting when Psm Lmt 1 equals 99.0. The generator will need to cut the prism in these instances.

If the lab blocks or uses ring sets, then set the ranges 1-5 in the increments of the prism blocks or prism rings at the lab.

Enter what you want prism < above limit to be rounded to (ex: 0.125)

Rounding increments for prism rings or prism blocker rings. Blocked or ring prism should be set to the availability of the prism set.                                                                                                                              

Enter number of digits to print after the decimal place for above prism

Enter upper prism limit 2. Prism <= limit will be rounded/printed per below

Maximum prism for the second set of rings.

Enter upper prism limit 2. Prism <= limit will be rounded/printed per below

Maximum prism for the second set of rings.

Enter number of digits to print after the decimal place for above prism

Enter upper prism limit 3. Prism <= limit will be rounded/printed per below

Maximum prism for the third set of rings.

Enter what you want prism < above limit to be rounded to (ex: 0.125)

Rounding value for the third ring set.

Psm DP 3

Enter number of digits to print after the decimal place for above prism

Psm Lmt 4

Enter upper prism limit 4. Prism <= limit will be rounded/printed per below

Maximum prism for the fourth set of rings.

Psm Rnd 4

Enter what you want prism < above limit to be rounded to (ex: 0.125)

Rounding value for the fourth ring set.

Psm DP 4

Enter number of digits to print after the decimal place for above prism

Psm Lmt 5

Enter upper prism limit 5. Prism <= limit will be rounded/printed per below

Maximum prism for the fifth set of rings.

Psm DP 5

Enter number of digits to print after the decimal place for above prism

Prism Need

Enter Y Prism Needed be printed on the work ticket

Blk Ring P

To print prism line for: B)locked, R)ings, A)ll, N)one on the work ticket

For printing of prism line on work ticket. Set to (B) for blocked prism, (R) for ring set prism, (A) for both types and (N) for neither type.

If the generator cuts the prism, set this to (N) Set according to the lab needs based on answers to PsmLmt 1-5.

Depending on this setting, this may print multiple lines of the work ticket with reference to prism requirements.

Flat Lmt

Enter the flattest curve the generator can cut (flatter will be roughed in)

Flattest curve the generator can produce.

If the curve falls below the range, the system will add 0.3mm to allow roughing in of the curve. The additional thickness is static at 0.3mm’s regardless of the difference. Setting the wrong value could induce thickness problems on high plus work.

Steep Lmt

Enter the steepest curve the generator can cut (steeper will be roughed in)

Steepest curve the generator can produce.

If the curve exceeds the range, the system will add thickness based on the difference between the wanted curve and the Steep Limit setting. The thickness is increased as the difference increases. Setting the wrong value will induce thickness errors.

Flex Comp

Enter material flex comp value (minus to steepen, plus to flatten)

Factoring amount to adjust rear surface curves due to flex (warp/stress) on the front curve during blocking. Optifacts assumes that the flex is greater as minus power increases, not on the center thickness value generated. Alloy blocking causes more flex than wax and usually requires a larger value than wax blocking.

Flex Comp adds the field value to the rear curve calculation before rounding. A negative value will move the rear curve towards more minus, while a positive will move the curve flatter. Flex Comp on minus jobs is calculated by multiplying the Spherical Equivalent against the Flex Comp value. The rear curve will be adjusted by the calculated value. Used in conjunction with Min Flx C. If the calculated value is less than Min Flx C, the Min Flx C is applied. On plus jobs, only the Min Flx C value is used.

Use extreme caution with this field.

Min Flx C

Enter minimum flex comp amount (minus to steepen, plus to flatten)

Used in conjunction with Flex Comp. This is the minimum amount of compensation applied until the power range, compensated, is larger than this minimum amount. This value is always used if the job is plus powered.

Pad Thick

Enter pad thickness in mm, -mm, or 0.0 if tools are cut compensated for pad

Amount in millimeters of the thickness of fining/polishing pads. A value of zero (0.000) indicates that laps are pre-compensated during manufacture. Any other value will influence the rear curve rounding for base and cross curves.

Normally this is the thickness of the 1-step fining pad used in surfacing. If the lab uses a 2-step fining process (2 pads) then the value should equal the thickness of both pads combined.

Prt Uncomp

Enter Y to print uncompensated exact curves also, if comp’ing for pad above

If (Y) and Pad Thick (above) are set  to compensate the curves, this will print the unrounded compensated curves on the work ticket.

Tool Sag

Enter Y to print tool sags, using next two entries

Only set to (Y) if the lab wants the sag value of the true front curve (lens) printed on the work ticket.

Ball Rad

Enter ball radius if you are printing tool sags

If the Sag Diam is of the ball tip variety enter the ball tip radius (1/2 the diameter of ball). This must be very accurate to produce proper sagittal curve values. Enter 0.00 for BAR type gauges. If the sag gauge (see sag diam) used is a BELL type, enter 0.00mm. This value and the Sag Diam value are used as the default sag printed on the work ticket if Tool Sag is set to (Y).

Sag Diam

Enter sag diameter if you are printing tool sags

Diameter of the sag gauge used at the lab for measuring curves. Typical gauge sizes are; 50, 45, 30 and 20 millimeters. This is only active if Tool Sag is set to (Y) for printing the sag value on the work ticket.

Elipt Err

Enter Y to print generator cross curve with elliptical error correction

For calculation of elliptical error (cross curve reduction) on old style generators. All 3-axis generators are self-correcting and this should be set to (N). In the event this is needed at the lab, the correction will be based on the standard wheel size used (3.50in.).

Cyl Comp

Enter starting cyl amount to compensate for material index

Cylinder value in which to start compensating for a material index. Additional cylinder compensation (tool index to material index) is applied when the cylinder exceeds the cylinder value entered here. The default value of 0.00 allows for cylinder compensation by material.

Slab Cover

Enter Y if mfr’ed slab-offs blocked with mfr cover (blk on cover & add)

If (Y) the system assumes you are blocking manufacturer slabs with a cover over the slab and add area.

Blk Diam

Enter the inside diameter of the blocking rings used

Default block size used in surfacing.  Superseded by the LOH Blocks Table if the entry is 0.00mm. A single block size can be placed here. If the lab only uses one size, enter the size.

Blk Shd T

Enter block shoulder thickness, or 0.00 is prism ring supports lens

Default block height used in surfacing. Superseded by the LOH Blocks Table if Blk Diam is entered as 0.00 and this entry is 00mm.

Height of block if a non-zero value was entered in Blk Diam field.

Psm Rng D

Enter the inside diameter of the prism rings used (0.0 if don’t use rings)

If prism rings used this value is the inside diameter of the ring. Set to 0.00 if no prism rings are used.

1D Psm Tk

Enter average thickness of 1 diopter prism ring

From 0.125 to 4.00 diopters. Typical value is 3.0mm.

4D Psm Tk

Enter average thickness of 4 diopter prism ring

Rng to Gen

Enter Y to add prism ring thickness to generator thickness

Used in conjunction with prism ring sets (1D Psm Tk and 4D Psm Tk). Set this to (Y) only if the lab uses the old style rings that are applied by the generator operator. This will add the prism ring thickness to the regular center thickness of the job. This keeps the generator operator from having to remember to add appropriate thickness.

Note: This will NOT apply to the Plano spacer ring. Thickness will be uncompensated for the spacer.

Md for Blk

Enter Y to modify generator thickness for block size

The amount of modification will be based on the front curve of the lens (sag) deviation between Blk Diam and Gen Diam.

The need for this is primarily based on the configuration of the generators in use and is typically applied on old style generators (based on Coburn standard of 50mm diameter) and using non-standard block sizes that did not conform to that standard. 3-axis generators have setting to compensate for this.

Gen Diam

Enter the inside diameter of the blocking rings that the gen. Is cal. for

Block diameter for which the generator is configured.  This will be a fixed value typically set to 50.0mm on older style generators and a variable in the set up tables on 3-axis generators. This value would become active only if the Md for Blk field is set to (Y).

Semi-Tech

Enter Y to calc. generator thickness for Semi-Tech blocker with fixed curve

For use only with Semi Tech (dual center) blockers.

Semi-Tech blockers laid the lens out on optical enter (MRP) then blocked on geometric center. It was a 2-stage blocker and there were limits to the amount of offset it could handle. Optifacts does not use the limiting factor. Instead it assumes the lab is using both 58.0 and 50.0mm blocks and the block base curve is 6.25 diopters. All lenses with a base curve other than 6.25 diopters will adjust thickness (to generator) based on the sag differences.

Gen Xmit

Enter Y to default to transmitting job to a connected generator

Gen Setup

Enter the setup number to use on the generator or 0 to use defaults

Material list value for Gerber generators. Enter the number from the table, or use zero (0) to use defaults.

% Cyl

Enter blank selection percentage of cyl to use for eff. Sphere power

Amount of cylinder, expressed as a percentage, to apply to the sphere power when selecting base curves.

% Str Rx

Enter blank selection percentage to stronger Rx to pick base curves by

This vale determines the amount of influence the strong lens power has on the direction of base curves.

ST up Sph

Maximum cylinder power under which to look for a stock lens during blank selection.

ST Lo Cyl

Enter blank selection lower limit of stock cyl power when picked first

Lowest cylinder power under which to look for a stock lens during blank selection.

Prt Nocut

Enter Y to have last blank selection no cut job print anyway

Set to (Y) the system will print a work ticket even if no lenses (in database) will work for this job. work ticket will show lens reviewed before making the “No Cut” decision.

Gen BC Lmt

Enter largest value generator base curve can be set to

Sets the maximum base curve for the generator. Used in conjunction with the Gen BC Set field. Set this field to (99) if all curves are available.

For use on older style generators to utilize a single base curve and altered thickness for production throughput. When the value entered here is exceeded the base curve entered in the Gen BC Set field becomes the base printed.

Gen BC Set

Enter base curve to set generator to if BC > above limit

Base curve used to calculate generator thickness if the Gen BC Lmt is exceeded. Typically this was set to either 6.00 or 7.00 diopters for speedy job setup on old style generators.

L No C Ax

Enter desired cylinder axis for left lenses with no cylinder

Angle to print and send to generators for sphere only, left lens. This is dependent on the model of the generator in use for this material.

R No C Ax

Enter desired cylinder axis for right lenses with no cylinder

Angle to print and send to generators for sphere only, right lens. This is dependent on the model of the generator in use for this material.

Loh Gen

Enter Y to calculate work ticket for a LOH generator or LOH blocker

Activates the standard thickness controls used by LOH generators. Prints the values on the work ticket as E-Value and I-Value. Must be (Y) to use LOH BLOCKS program. Setting this to N when the lab only uses LOH blockers, will cause the system to ignore the LOH Blocks table.

Bkside Mk

Enter Y to calculate work ticket for backside markup

Reverses the layout instructions (surfacing) for applying ink mark to the rear side of lens. Normal layout is on the front side of lenses.

Rot + Tools

Enter 1 through 5 to rotate sph. And cyl. Curves when curves(s) are plus

Set to zero (0) to disable this feature. Other acceptable entries are 1 through 5.

0 = No rotate.

1 = Rotate if either curve is + (does not alter cy or prism axis)

2 = Rotate if both curves are + (does not alter cy or prism axis)

3 = Rotate curves and cyl axis if either curve is + (does not alter prism axis)

4 = Rotate curves and cyl axis if both curves are + (does not alter prism axis)

5 = Rotate curves, cyl axis and prism axis if either curve is + and the absolute value of the sphere is greater than the absolute value of the cross curve.

Pol 2mm

Enter Y to default to 2mm thick Polarized lenses

If set to (Y) will assume all Polaroid lenses use a 2.0mm thick wafer (lamination layer) and set the center thickness accordingly. Default answer should be (N) unless the Polaroid products in the lab are of the older manufacturing process.

Edge Shape

Enter default frame shape for edged jobs (1-6)

Uncut Shape

Enter default frame shape for uncut jobs (1-6)
