Chapter 1: The ES-curve Edger
General Description
The ES-curve edger is a device comprising mechanical, electrical, pneumatic and software elements whose
function is the precise machining of resin ophthalmic lenses. This includes edging with a large variety of
contours, drilling and milling. The edger is equipped with a tool-changing mechanism that permits all such
operations to be performed without the user needing to manually change tools or remount the work piece.
Additional flexibility is achieved via five primary axes of motions, including tilting the axis of rotation of the
work piece. This allows, for example, very high-wrap lenses to be dynamically beveled or grooved, and
complex shelf cuts to be made.
The ES-curve is contained within a single floor-standing cabinet, mounted on casters so that it may be easily
repositioned for access to all points within the cabinet. The top-front of the cabinet swings up to open for
maintenance access to the machining area. A smaller door in the center-front of the unit opens/closes
vertically to allow insertion or retrieval of the lens, or access to the tool store. The touch screen display is
above the door.
All doors and access panels must be closed in order for any motion in the machining area to occur.
Installation
Installation of the ES-curve edger is normally included in the sales conditions and is therefore performed
by personnel authorized by the machine supplier.
Transport and Handling
The machine weighs about 700kg.
The machine may be moved in the following cases:


Loading or unloading from the means of transport.
Movement inside a lab or production facility.
In the loading and unloading operations, the machine must be lifted using a fork-lift truck. The fork must
be adjusted in a way to be inserted into the designated lift points.
The machine is mounted on casters, allowing movement on flat, smooth surfaces. The rear wheels are
fixed and the front ones swivel.
The manufacturer is not responsible for any damage due to incorrect handling.
ES-curve 5-Axis Ophthalmic Lens Edger User Manual (Software Version 4.0 or later)
9
Positioning
The ES-curve must be installed so that a space is left behind the cabinet to allow the inspection of the
parts located in the rear of the machine. These require periodic maintenance to guarantee optimal
operation of the machine over time.
Unpacking
The machine should be unpacked as close as possible to its final operating location. This reduces the
likelihood of damage caused by vibration and jarring while moving the machine.
Do not use sharp tools to remove packaging materials to avoid marring or damaging the machine.
Connections to Sources of Energy
Do not connect the ES-curve to external energy sources until it has been correctly positioned. The
following connections are necessary:


Electricity
Compressed Air
Electrical Connections
ATTENTION !
The customer's source of electric power must have the protections specified by the standards in force in
the country of use. Moreover, the power source must be able to continuously supply the maximum
power that the machine may draw.
The machine is supplied with a power supply cable with three poles, and ground. The user must connect
this cable to the power source and supply it with a plug that is in compliance to those in use in that
particular country. The connection to electricity or connection of the plug must be performed by
specialized staff.
Pneumatic Connection
The inlet is found in the left side of the machining unit and includes a FR unit for filtering and pressure
adjustment (preset in the factory). Insert the connection pipe (Type 10/8 in polyurethane or Rilsan
polyamide resin). Increase pneumatic pressure gradually to avoid whiplash of the supply line in the event
that it is not solidly connected.
WHIPLASH HAZARD
Solidly connect the compressed air piping. Open the valve slowly.

Major Subsystems Overview

Machining
The machining system consists of a high-speed spindle which rotates the selected cutting tool. The
spindle traverses left and right, front-back, and up-down to engage the tool with the work piece. Also
included is a lens probing system, a tool-length calibration pad, and the tool store holding up to seven
tools. Pneumatic jets clear chips from the machining area. Cooling is provided both for the spindle and
for the tool/work piece interface.

Lens Positioning
The lens positioning system secures the blocked lens for machining using a chuck below the lens that
engages the block and a clamp arm above the lens which holds the lens in place. The positioning system
rotates the lens so that the tool engages points around the lens perimeter, and tilts the axis of rotation to
affect the angle at which the tool engages the work piece.

Motion Control
This subsystem consists of the servo motors that activate each of the axes via toothed belts, position
detectors, and electronic elements which allow the position, velocity and acceleration of each axis to be
precisely controlled. The motion control system is inside the cabinet and not generally accessed directly
by the user.

Programmable Logic Control (PLC)
A specialized processor called the PLC sequences the various steps in the edging process. Like motion
control, it is not generally accessed directly by the user.

Computer and Graphic User Interface (GUI)
The computer subsystem provides communication with an external host computer to download job
information, and computes all of the parameters of the edging cycle (axis positions, speeds, feed rates). It
directs the other subsystems accordingly to assure that the desired edging cycle is achieved. It
interfaces with a touch screen display to provide a graphics user interface (GUI) with the user. This may
be used to enter job data and cycle parameters, to report and display cycle status, and to perform
maintenance and diagnostics. The computer has access to a large fixed disk storage device, as well as to a
USB key which may be used to update the ES-curve software.

Miscellaneous
Included within this category are the safety devices, status sensors, pneumatics, filters, lubricant
reservoirs and the like.
Many of the items discussed above, as well as other items of interest, are illustrated in the figures found at
the end of this chapter.
Axes of Motion
The edger implements five axes of motion as follows:
X axis: Transverse motion (left/right) of the cutting tool
Y axis: Orthogonal motion (front/back) of the cutting tool
Z axis: Vertical motion (up/down) of the cutting tool
C axis: Work-piece rotation
B axis: Inclination (tilt) of the C axis
ES-curve 5-Axis Ophthalmic Lens Edger User Manual (Software Version 4.0 or later)

Electro-Spindle
The electro-spindle provides high-speed tool rotation. The speed of the electro-spindle is selected by the
operator via the user interface. This can be adjusted electronically up to a maximum of 30,000 RPM;
however, larger diameter tools should not be operated at more than 20,000 RPM. Optimum speed
depends on many factors: Target cycle time, desired finish, type of tool, etc. The electro-spindle
incorporates pneumatic cleaning systems for improved operation.
A constant flow of air at 1-1.5 bar prevents dust and shavings from entering the spindle and
contaminating the high-speed bearings. The spindle is constantly cooled by circulating a solution of 85%
water and 15% Ethylene Glycol. The fluid/air heat exchanger is found on the back of the machine and
can be inspected by opening a rear hatch on which indicators are found that warn of any malfunctioning.
Cooling requires only ambient air. If the ambient air temperature is too high, further machining is
disabled to prevent overheating the spindle.
The coolant should be replaced at least yearly. The heat exchange coils should be cleaned at 1 to 3-month
intervals. This operation can only be carried out with the machine at a standstill and after sources of
energy have been disconnected. A vacuum should be used to clean the heat exchanger coils. Compressed
air must not be used.
Tool Taper Cleaning Jet: In the automatic tool loading and unloading phases, a jet of compressed air
cleans the area of contact between the spindle and tool. The jet is intense and has a duration of about one
second.
Tool Vise Sensor: Tool changes are under software control. Software controls the selection and
attachment of the desired tools from the tool store. The spindle can only rotate if a tool is properly
attached. There is an electronic sensor that identifies the following cases:



The spindle vise mechanism is open.
The spindle vise mechanism is closed but the tool is not detected.
The spindle vise mechanism is closed and the tool is properly detected.
Tool Store
The tools are housed in a fixture called the tool store. It incorporates an access hatch which is always
closed during machining to prevent dirt depositing inside. An automatic system opens the hatch only
during the tool change phase. There are seven tool positions available inside the tool store. When tools
are loaded into the tool store, or replaced, it is essential that the position of the tool in the tool store and
the tool’s dimensional properties be accurately recorded via the control software.
ATTENTION!
The control software identifies tools by their position within the tool store housing. There is no
additional sensing mechanism.
When any tool is changed, it is essential to insert the new dimensional and performance features into
the control software and to insert the tool into the correct housing position.
ES-curve 5-Axis Ophthalmic Lens Edger User Manual (Software Version 4.0 or later)
12
Tools
ATTENTION!
Only balanced tools with dimensions that are compatible to the machine should be used on the
machine.
When inserting new or re-sharpened tools, it is absolutely necessary to perform the following before
any machining:
 Enter the new dimensional data.
 Check the length on the tool calibration system (presetting).
Always ensure that the position of the tool corresponds to that specified in the software program.
Cooling the Tool and the Lens Being Machined
The tool cooling system consists of a coolant reservoir tray and a pneumatic pumping system. Coolant is
dispensed through a small ejector nozzle. The software selects the cooling mode necessary in each
individual phase of machining. Cooling of the tool, when necessary, uses air mixed with distilled water.
The edger will sense a low coolant level and notify the operator to refill the tank. The consumption of
liquid is estimated at about one liter every 200 pieces.
Vacuum
The edger has an integrated vacuum system mounted in the lower-front part of the machine. It can be
easily accessed by opening the door under the machining area. The vacuum is controlled directly by
software and failure causes the machine to stop.
The vacuum requires periodic maintenance to empty the bag and clean filters which, through time, tend to
become blocked.
Electric Control Board
The rear electrical cabinet is completely isolated from dirt, dust and moving parts. To work on the
electrical cabinet, disconnect all electric power. Maintenance of the electrical cabinet is generally
performed by trained service personnel.
Pneumatic System
The air intake includes a pressure adjuster, air filter and oil filter. The pneumatic valve assembly is
located in the rear of the unit.

13
Programming Unit
The ES-curve is supplied with an integrated industrial PC, located in the upper-back of the machine in a
position protected by fixed shields. Two external USB ports are made available for exchange of data or
attachment of a barcode unit.

Chapter 2: Operation
This chapter explains how to use the ES-curve edger in normal operations. Maintenance operations are
described in a later chapter. The primary user interface to the edger is the touch screen, described in
detail later in this chapter. For certain operations, however, a hand wheel controller is available for
limited manual control.
Operators
The edger should not be operated except by personnel familiar with the machine’s operation. However, a
high level of professional knowledge of opticianry is not required.
Any routine and periodic maintenance should be performed by specialized staff that fully understand the
problems of safety highlighted in this manual.
The staff engaged for extraordinary maintenance (e.g., refurbishment or repair) must be highly
professional and have sufficient experience regarding the management of machines with significant
content of electronics.
ATTENTION !
It is recommended that the After-Sales Service be contacted before performing extraordinary
maintenance in the case of breakdown.
.
Manual Hand Wheel Functioning Mode
The edger can be controlled manually using the hand wheel, decoupling the axes from the embedded
processor. This must first be enabled through the Diagnostic Screen. Some typical operations used with
this instrument are:

Edging Scenario
The term “edging” is used in a general sense to refer to any or all of the machining operations provided by the
ES-curve, except in cases where a specific operation needs to be identified (i.e., drilling, shelving, etc.).
The edging process may consist of the following steps. Specific actions mentioned here are described in
detail later in this chapter.

Enter job information. Job data includes, for example, data describing the shape of the edged lens, the
specific operations to be performed, properties of the lens blank, shape and location of special features
(holes, slots, shelves, etc.) and machining parameters (tools, feeds and speeds). In most laboratories, this
data is downloaded electronically from a lab host computer. The user should check the data to assure that
all needed data is present and accurate. Manual data entry is available to supply missing values or to
override downloaded values. Downloading requires only that the user enter a job or tray number; the job
data and a drawing of the edged lens appear on the display. Alternatively, the ES-curve allows frequentlyrun jobs to be stored internally and retrieved from memory when desired.

Mount workpiece. When the access door opens, check the cutting chamber to be sure that there are no
obstructions to machine movement. The blocked lens is placed (block down) on the chuck and the clamp
is engaged to secure the lens with pressure from above. Some ES-curve edgers are equipped with robotic
(automated) lens mounting. The operation of the automated subsystem is described elsewhere.

Edge. The access door closes, the required tool is fetched from the tool store and the machining begins.
The actual edging process may occur in multiple phases, depending on the specific job: Rough cutting,
beveling, safety beveling, drilling, shelving, polishing, etc. The ES-curve selects the appropriate tool(s)
for each phase; tools are automatically fetched and mounted as required.

Remove workpiece: When the edging cycle is complete, the door opens and the workpiece may be
removed. A recut cycle is available which allows small changes to be made to the shape to improve
sizing, finish or fit. If the removed lens is the first of two for a job, the data for the second eye may be
accessed.
System Startup Checks
The ES-curve can only function with the cabinet closed. It is essential that the door and cabinet
interlocks be checked periodically as described in the chapter on maintenance. The manufacturer
disclaims any responsibility for any injury to persons caused by a lack of maintenance or
disabling/removal of the protective interlocks.
Optimum operation of the edger requires that fluid reservoirs be maintained at appropriate levels and
filters be cleaned periodically. Emergency stop buttons should be released prior to startup.
Requirements for fluid levels and filters are discussed in detail in the chapter on maintenance, but
summarized here.
ES-curve 5-Axis Ophthalmic Lens Edger User Manual (Software Version 4.0 or later)
23
Spindle Cooling System
The spindle operates at high speed and it must be cooled. A pump is used to circulate coolant to the
spindle. The coolant storage tank must be replenished with de-ionized (or distilled) water mixed with a
Propylene Glycol or Ethylene Glycol based antifreeze. Use an automotive type antifreeze that contains
corrosion inhibitors. Do not use tap water because it may cause scaling. The final coolant liquid should
be 85% de-ionized water, 15% concentrated antifreeze by volume. Mix 30% antifreeze and 70% deionized water if a 50/50 pre-diluted mix antifreeze is used. See the ES-curve Maintenance Schedule in
this manual.
Before startup, check that the level of cooling liquid is within the established limits. As the system is a
closed circuit, the level should not change appreciably in the short term. A continuing decrease in fluid
level indicates there is a leak in the circuit. Call maintenance staff in order to troubleshoot the leak.
Before restarting the machine, top-off the coolant until it reaches the desired level. The coolant must also
be changed periodically.
Cooling System for the Tool and Lens Being Machined
A reduction of the level of tool cooling liquid prevents the processing of some jobs. The tool/lens cooling
liquid is not recycled, thus its level should be checked and topped-off before each startup or shift.
Vacuum
Cleanliness of the operational area is provided by a vacuum located under the operational area. The bag
and filters in the vacuum must be checked and changed periodically for optimum cleaning action.
Compressed Air Supply
The compressed air filter can clog due to the accumulation of dirt in the operating environment. Before
startup, always check and flush the compressed air filter. The filter must be replaced periodically
depending on the operating environment.
Graphic User Interface (GUI)
This section describes the screens used to configure and operate the edger. Each screen is shown in a
figure and the use and significance of fields on the screen are described thereafter.
Many screens include a keypad that is used to enter commands and numeric values. Tap the keys lightly
with the fingertip or a stylus designed for touch screen use. Do not use sharp objects such as pencil/pen
points, paper clips, etc. on the touch screen. To enter a number, first tap the field that is to receive the
input value; it will be shown in yellow. Press the Clear control to erase any existing entry. A newlyentered value may be made effective by tapping Enter, or by selecting a different field, or by tapping
Start. Some screen controls act as toggles; repeatedly tapping a toggle control causes it to cycle through
its allowed values. Tapping a check box enables or disables the associated option. Navigation between
screens is accomplished via control buttons on the left side of the screen, or across the top.

Material Screen
The ES-curve can machine all resin materials used for ophthalmic lenses. However, each combination of
tool and material may require different operating parameters for optimum performance. The Material
Screen permits operating parameters for each combination of tool and material to be entered and edited.
When you specify the material on the Job Screen, the ES-curve edges according to the speeds and other
data listed on the Material Screen. There is a General tab, plus additional tabs for each cycle phase. To
edit a field, first select the desired tool and material. The General tab provides data which is only material
dependent not associated with any specific tool.

Chapter 3: Calibration
Overview
The ES-curve edger and its tools are manufactured to strict tolerances; however, there are minute
dimension variations among machines, and over time. The process of calibration measures these
variations so that the software can compensate for them, resulting in accurate size of the edged lens.
In general, the calibration process is to edge a lens, measure the edged lens, compare the measured value
to the desired value, and use the difference to compute a calibration offset. The ES-curve performs many
required computations. In some calibrations, the tool tip is brought into contact with a fixed location
within the machining area. This allows the tool length to be automatically computed. Calibrating safety
bevels does not involve computation; rather, the user inspects a safety-beveled lens and adjusts the depth
of the bevel as required. Calibrations which require that a lens be edged use internal job number 002.
This is a 58 mm diameter circle. Use a caliper to measure the diameter of the edged lens.
First Time Calibration
1.
Access the Tool Screen as shown below and define the tools that are installed in the machine and
verify the details of each tool.
Figure 3.1
ES-curve 5-Axis Ophthalmic Lens Edger User Manual (Software Version 4.0 or later)

2. Access the Material Screen and click the Restore All button for each tool to ensure Standard
settings.
Normal Calibration
Access the Calibration Screen as shown below and place a check mark next to each calibration step you
wish to perform. If you select individual steps rather than selecting all steps at once, they should always
be done in the same order they appear on the screen. After selecting the calibration steps to be done,
press Start to begin with the calibration steps.

Basic Calibration:
This section is used to define the approximate mechanical relationships of the spindle, chuck, and tool
store. These steps should be followed for first time calibration, and require use of the hand controller as
described in Figure 2.1.
1. Spindle to Chuck – Use the hand controller to move the spindle with the 20mm cutter above the lens
chuck to set the approximate X, Y, and Z position as shown in the photo below. Press OK after
adjusting the cutter tool into position.
Figure 3.3
2. Probe to Chuck – Use the hand controller to move the Z axis so that the bottom of the probe is
approximately 3mm above the chuck collar, the X axis is positioned at the right side of the clamp, and
the Y axis is set to the center of the clamp as shown in the photo below. Press OK after adjusting the
probe into position.
Figure 3.4

3. Probe to Calibration Pad – Use the hand controller to move the Z axis so that the probe tips are
centered on the probe pad, the X axis so the probe tips are on the right side of the probe pad, and the
Y axis of the probe tips are in the center of the probe pad as shown below. Press OK after adjusting
the probe into position.
Figure 3.5
4. Tool Storage – Use one hand to hold onto the 20mm cutter tool firmly and then press OK to release
the tool from the spindle. Place the 20mm cutter tool into the tool store in the first location. Make
sure the tool is flush with the back of the fork and press OK. Use the hand controller to move the
spindle into position directly on top of the 20mm cutter tool as if inserting the tool directly into the
spindle. Press OK when spindle is in position as shown below.

materials to be machined.
Use of the machine will produce dust and residue. The user must keep the machine suitably clean in
order to prevent the accumulation of chips and debris causing, for example, a greater effort in machining
or difficult mechanical movement. Excessive effort of the tool due to the particular hardness of the
material or incorrect programming of the work parameters (axes speed, rotation speed of the milling
cutter, etc.) can cause the tool to break, possibly causing fragments of the tool or work piece to be ejected
at high speed. The case surrounding the machining area is designed to resist the projection of chips. Any
fluid spills or leaks should be cleaned promptly to prevent slippery conditions around the machine.
The machine has been designed to work resin materials only. Other material could cause excessive effort,
quick wear of the tool, or tool breakage with expulsion of tool and work piece fragments.
Do not remove protections!
It is prohibited to test tools with the cabinet open. For any other tests that
can be performed with the guard open, e.g. in the case of maintenance by
specialized staff, the person in charge must wear protective gloves and
goggles.
