Basic functions

Best suited functions for milling machines!

Zero-setting

PresetMeasurement direction setting

The display can be set to "0" (zero) at any
scale position.

This function allows the user to enter a numericvalue on the counter display.

The readout can be set to count up or down ineither direction of scale movement, whichever ismore convenient for the operator.

Zero approach machining[INC mode] (KA-200 Counter)

Pitch machining

Scale reference point
settingZero approach machining can be repeated atpreset intervals. Since the counter keeps the total
displacement in absolute coordinates, a positioning
error made by the operator at one tooling position
has no effect on the remaining positions.

Bores multiple holes between two arbitrary points
in the X-Y plane at equal pitch. By inputting thenumber of holes and positions of the start and end
points, holes can be bored easily at equal spacing.

● Scale reference point
The position reference marked on the glass scaleof the scale unit is the absolute origin point and it
has highly accurate positional reproducibility. Whenthe scale absolute point is passed through, a countfrom the preset values (zero-set or preset values) ora value to be displayed when passing through can
be fixed. That is, it can be used when memorizingor reproducing the machine origin or the machiningreference point.

(KA-200 Counter)

Errors due to table positioning by the machine areautomatically corrected to the next target value.

mm/inch conversion

Unnecessary lower digits (up to 4 digits of thelowest digits) can be blanked out.

This function halves the display value.

The counting unit can be changed between"mm" and "inch" (or between "mm" and"E (=1/25.4 mm)" depending on the model.)Resolution setting
The display resolution can be selected from among

When the AT715 is connected, the display

Although both the scale and the counter use the incremental system,
detecting the origin point on the scale enables using them as absolutecoordinates.
Thus two coordinate systems are available:● Absolute coordinate system
When measuring by defining an arbitrary coordinate point as a reference,setting the machine origin to 0 is convenient. This coordinate system is also
usable when an arbitrary workpiece point is set as a reference point, andsetting a datum point on the workpiece to 0 is convenient in this case.
● Incremental coordinate system
Use this system when successively measuring with an arbitrary point asa reference point. In this case, performing zero-setting each time whenreaching an arbitrary point is convenient.

Machine errors caused due to workpiece weight,
inaccurate table adjustment, etc., are linearly
compensated to reduce the positioning error.

Turning on ʻsmoothingʼ slows display updating toenable the display to be read more easily when ameasurement value is rapidly oscillating due tomachine vibration. Measurement speed remains
unaffected.

Clears the setup parameter data and resets to thedefault data.

The doubled scale displacement can be displayed.
This convenient function can be used to display thediameter of a workpiece during a turning operation.

Pitch Error Correction(KA-200 Counter & AT100 Series)

This function allows correction of machine errors,
thus improving positioning accuracy.

This function multiplies the actual countermeasurements by a constant factor. This is usefulin, for example, mold manufacture by allowing
the mold to be machined to the actual moldedcomponent dimensions directly, without having toincrease the machining dimensions manually toallow for material shrinkage after molding. Tediouswork can thus be reduced and the risk of mistakes
in calculation eliminated.

workpiece as a reference point and it can display
the diameter of the machine workpiece by using
absolute coordinate. The counter can zeroset/

Precautions when mounting and handling Linear Scales
Selecting the scale unit mounting position andmounting method

Checking parallelism andadjustment of scale unit

It is important to keep in mind the following four points when determining thescale unit mounting position and orientation.

In order to attain maximum accuracy, the scale unit must be mounted parallel to themachine guide (machining axis). Incorrect mounting may cause the scale unit to bendor twist.

Mount the scale unit making sure that the unit including the detector head
and the cables does not interfere with any part of the machine. To facilitate
mounting, mount the scale unit and the brackets on machined surfaces wherever
possible.
■ Protection from machining fluids and swarf

・Parallelism tolerance: Refer to scale specifications.

(mountingorientation)

The scale unit is constructed in such a way that machining fluids and swarf
cannot easily enter into the interior of the unit. However, since the openings areprotected from entry of foreign material with rubber seals only, avoid directly
exposing the scale unit to machining fluids and swarf. Select the mounting
orientation of the scale unit after carefully considering the direction in whichmachining fluids and swarf are sprayed and scattered.

directions along mounting surface (up and down).
・Checking position: Position of the scale unit near the mounting plate and themounting block
StrokeTableℓLinear Scale■ Other considerations

・If the detector head moves, the signal cables also moves with the slide table.

This should be considered when laying out the signal cables. It is therefore
recommended to mount the scale unit on the moving part of the machine.
・Mount the scale unit in a place where it is not directly subjected to airflow.
When removing swarf using an air gun, be careful of flying swarf.
・The scale unit must be mounted in a place where maintenance can be easily
performed.

Detectorhead

Radius: 50 mm or larger
Fixing■ When the cable is movable
Flexible cover
When the detector head is the moving
Detectorheadelement, it carries the signal cable with it
during operation. Take care, in such a case,Radius: 100 mm or larger
that the radius of curvature of the signal
cable is not smaller than 100 mm and excessive force is not applied to the cable.
It is a good idea to protect the cable with a flexible support cover.
Note: It is important to ensure that the signal cable does not interfere with, and is not chafedby, any part of the machine.

■ Other considerations
The signal cable is durable enough to withstand repeated bending up to
approximately 2 million times (when the bending radius is limited to more than 100mm). When repeated bending exceeding 2 million times is expected, the signal cableshould be considered as a consumable part. In such a case, carrying a spare cable willallow immediate replacement when necessary and so minimize machine downtime.

■ Temperature cycle (dynamic characteristics) test
Testing has proven that there is no abnormality when the Linear Scale is used under
the condition where the ambient temperature continuously changes within thespecified range.
■ Vibration test (Sweep test)
Testing has proven that the Linear Scale functions without abnormality when subject
to vibration within the frequency range 30 Hz to 300 Hz at a maximum accelerationof 3 G.
■ Vibration test (Acceleration test)
Confirms that there is no performance abnormality of a unit subject to vibrations at a
specific, non-resonant frequency. (Approx. 10 G)■ Noise test
In accordance with the EMC Directive, EN61326-1■ Crate Drop Test
In accordance with the heavy equipment drop test (JISZ0200) specified in the JIS
standard.

● Adjusting the mounting surface

between the scale mounting surface andthe mounting block or the mounting plate.
● Adjusting along (up and down)

Adjust by sliding the mounting block or the mounting plate onto the mounting
surface.

■ When the cable is fixed
The radius of curvature of the signal cablemust be larger than 50 mm.

■ Testing within the operating temperature range
Testing has proven that there is no abnormality of functions and signals when the Linear
Scale is used within the specified operating temperature range.

Dial test indicator

Up/down

The total system accuracy of the machine on which the scale unit is mounted is
not only determined by the scale unit accuracy but by the machine accuracy as
well. Particularly for machines with slide tables, geometrical errors may occur,depending on the straightness of moving parts; Thus, the scale unit must be
mounted in a way that these errors are minimized. If the slide table moves not
linearly but curvilinearly, errors occur in proportion to the distance "ℓ" between
the scale unit and the machining point (cutter position). Thus, mount the scale
unit in a position that minimizes "ℓ".

Motion of table

・Checking direction: Back/forward direction on mounting surface andDial indicator■ Accuracy considerations

Machining point■ Checking parallelism
Use a dial indicator as shown in the figure below. To adjust the parallelism between
the scale unit and the machine guide, check the parallelism while manually moving
the machine's movable part such as the slide table, or measure the parallelism withreference to the guideways of the machine or equivalent reference surface.

It is important to keep in mind the following points when deciding on the layout
scheme for signal cables.
FixingEach object has a natural frequency of oscillation, depending on its shape, length,
and the type of material. The Linear Scale frame is not an exception. It has its natural
frequency and thereby resonates at a certain frequency. In general, this will notcause a problem, since a machine tool and the Linear Scale frame have different
natural frequencies under normal machining conditions. However, should the natural
frequency of the machine tool body and the Linear Scale coincide, which can leadto performance abnormalities due to excessive vibration amplitude, the following
counter-measures can be taken.
［Remedy］
Remedy for scale
1. Increase rigidity of the mounting bracket for the scale.
2. Add a mid-support to the middle of the scale to shift its resonance point higher.
Remedy for machine
3. Mount the Linear Scale at a place where vibrations from the machine tool cannot
be easily transmitted.
4. Limit the machine process conditions to be within a specific range in which thenatural frequencies of the machine tool and the scale do not coincide.

Information about Air Supply(Improvement in Dust and Oil Resistance)
Feeding clean compressed air into the scale unit is provided as a means of improving
the environmental resistance (to coolant and dust) of assembly-type linear scales. Thisis done by piping air to either of two M5 screw holes situated on the sides of thescale unit.
Note: AT103 is equipped as standard with an air supply fitting.
Caution: This air supply method is suggested as optional protection for the scale.
The installation of the air supply piping is important and should be
implemented as described in the manual. The air should be filtered and thefilter replaced periodically, depending on the cleanliness of the air source.
Continued use of a heavily contaminated filter may allow contaminants topass into the scale unit.
For detailed information, contact the nearest Mitutoyo Sales Office.

Maintenance of dust-proof seals
In order to maintain and extend the life of the dust-proof rubber seals, it isrecommended that a small amount of silicon lubricant be applied to the contact area
between the rubber and the detector head once a year. (The maintenance frequency
slightly differs depending on the operational conditions of the scale.)
Greasing

directions when the detector

installation. In addition, this structureis highly rigid and therefore has excellent durability.
2. Water-proof Connector
A waterproof/splash-proof connector is used to enable separation of
the signal cable. Thus, installation and maintenance of the Linear Scalecan be easily performed. (Only for AT100 Series)
3. Conduit armored type signal cable
The signal cable is protected by the conduit system. Its exterior is made ofstainless steel, which is corrosion-resistant and withstands continuous use.
4. Unique rubber seals
The slider is shaped to glide smoothly throughthe rubber-seal opening – almost like thekeel of a boat through water.
5. Excellent splash- and dust-proof
rubber-seal structure
The rubber seals are made of a strong, special urethane, and wires are inserted inthese seals to improve the splash-proofing and dust-proofing of the scale.
