2.6 Setting the Compensation Mode
Term
Linear and non-linear error:
There is an error between the measured value and standard value of the
grating rule. If the two measurement curves are in an identical shape within
the grating ruler’s range of travel but not in coincidence, this is called a
linear error. If the two measurement curves are in different shapes, this is
called a non-linear error.
Linear correction: to compensate for the linear error so that the displayed
value is equal to the standard value.
Note: The linear error correction value is set by the installation
personnel, and must not be modified by the user at will, which otherwise
would affect measurement accuracy.

Error correction has two setting types: 1. Linear compensation; 2. non-linear

compensation.

For example: Set the compensation mode

on axis X to non-linear error correction.

must be in accordance with the type of each axis. Therefore, you need to
only modify the parameter of one axis, and the parameters of other
axes change accordingly.

Note: If the modification of system parameter

setting is in confusion, you can use the “Factory
Value” (DEFT)function key to restore to factory
defaults.

 Chapter IV Auxiliary Zero Position
Function of the 200 Group User
Coordinate System
The display provides three coordinate systems: absolute coordinate
system (ALE), relative coordinate system (INC) and 200 group user
coordinate system (ZER 001 - ZER 200). The 200 group user coordinate
system can be used as the auxiliary zero point during processing.
ALE is the absolute coordinate system which is established at the
beginning of work-piece processing. The 200 group user coordinate system
is defined relative to the absolute coordinate system. When the user’s ALE
coordinate changes, the ZER zero position changes along for an according
distance.
During work-piece processing, one benchmark zero position is often not
enough to meet user needs, but currently added ZER coordinate system can
provide multiple benchmark zero points for users. Each auxiliary zero point
is equivalent to a coordinate system origin defined by the user. Every point
in this coordinate system takes the auxiliary zero position in current ZER
coordinate system as the benchmark. In such a relatively independent
coordinate system, the processing for all kinds of special functions can be
carried out.
To process the work-piece shown in the figure, ALE origin is set at
point 0 of the work-piece center, and the rest four auxiliary zero positions
are points A, B, C and D, as shown in the figure.

20
 The auxiliary zero position can be set in two ways:
1) Coordinate entering;
2) Zero clearing in place.

4.1 Entering the ZER Zero Position Directly

Without moving the machine, follow the dimensions on the user
processing drawing to directly preset the user coordinate zero point, In this
way, the user coordinate zero point can be set precisely and quickly.
In the user coordinate system (ZER coordinate system), enter the
coordinate of an auxiliary zero position at the absolute coordinate zero
position, and the coordinate position of absolute coordinate zero (point 0) in
the auxiliary zero position coordinate is displayed. Viewed in the relative
coordinate system, point 0 is at (25,-20) of point A, (-30,-25) of point B,
(-30,30) of point C, and (25,20) of point D, exactly the opposite numbers of
position of each point in the absolute coordinate system. If you enter the
relative zero position at a point outside of the absolute coordinate system,
the position of this point in this user coordinate is displayed. If you enter the
auxiliary zero position of point B in the user coordinate at point A, the
displayed value of B is (-55,-5). Therefore, when a value is preset in the ZER
coordinate system, a minus is added to get the opposite number
automatically. Hence, the coordinate value of the processed work-piece can
be directly used for entry.

Operating steps：

1. In the absolute coordinate system (ALE), move the machine and aim
the tool at the center point 0 as shown in Figure 3.1.
Press keys X0 and Y0 for zero clearing for data on axis X and axis Y
and to determine the zero position of the absolute coordinate.

2. Press the “ZER” function key to

enter the user coordinate system.
Enter the ZER 1 coordinate, set
the position of point A, and enter its
coordinate value (-25,20). If you
find that the entry is wrong,
press the axis key to cancel the entry.
push
push

21
 3. Press the key to enter the ZER 2 coordinate system, set the
position of point B, and enter
its coordinate value (30,25).

push
push

4. In a similar way, follow Step 2 to set auxiliary zero positions for

points C and D.
5. After setting the auxiliary zero positions, you can process the
work-piece in the coordinate system of corresponding auxiliary zero
position. As shown in the figure, you can process equally divided
holes for an arc in point B’s coordinate system of auxiliary zero
position.
6. After the processing is completed, press the “A/I” function key to quit
the ZER coordinate system.

4.2 Zero Clearing in Place

1.Move the tool to the absolute coordinate.
2. In the absolute coordinate system (ALE), as shown in Figure 3.1, move
the tool to point 0, press keys X0 and Y0 for zero clearing for the data on
axis X and axis Y, and determine the zero position of the absolute
coordinate. (If reprocessing the work-piece, the user can clear all of the
ZER coordinate system and then conduct setting again.)

3.Press the “ZER” function key

to enter the ZER 1 coordinate, set
the position of point A, and move
the tool to point A. The display shows

Press keys X0 and Y0, and the ZER

coordinate of point A is set successfully.

4.Press the key to enter ZER 2,

set the position of point B, and move the
tool to point B. The display shows
Press keys X0 and Y0, and the ZER

22
coordinate of point B is set successfully.

5. In a similar way, follow Step 3 to set auxiliary zero positions for points C
and D.

6. After the processing is completed, press the “A/I” function key to quit the
ZER coordinate system.

7. When work-pieces of the same size are processed, as long as the set ALE zero
point is behind point 0, the ZER zero point is set automatically. As shown in
Figure 3.1, enter the ZER 1 coordinate system, move to a position where the
displayed values on both axis X and axis Y are 0, and this position is the
benchmark point of the ZER 1 coordinate system. The user can process
work-pieces based on this. In mass processing, with these user coordinates,
the time spent in setting the coordinate zero point can be saved greatly, so that
the processing efficiency is improved.

Attention:
 When the user coordinate is used, zero clearing in corresponding user
coordinate system is actually resetting the auxiliary zero position. The
position at which zero clearing is conducted is the new user coordinate
origin, and the coordinate origin set originally is replaced by the new
coordinate origin.
 When the user coordinate is used, middling in corresponding user
coordinate system is also resetting the auxiliary zero position. The new
coordinate origin is at its middle point, and the coordinate origin set
originally is replaced by the new coordinate origin.
 Press the “REF” key for ten times to clear all of the ZER coordinate
system. After clearing, the 200 group coordinate is the same as the ALE
coordinate.
 When resetting the ZER coordinate, you must conduct zero clearing for
the data on axis X and axis Y in the ALE coordinate system, and set the
absolute coordinate zero position. Otherwise, the set ZER coordinate is
wrong.

5.4 Simple arc processing
When processing moulds, it is often required to process arcs. In case
the shape is simple and the production quantity is very small, resources may
be wasted if a numerically-controlled machine tool is used. The function of
simple arc processing is provided at the display so that a single work piece
such as a copper pole of a mould can be conveniently and quickly processed
at a general milling machine. With the control parameter“MAX CUT”, make
the arc to be cut every time equal. Control the smoothness of the arc. When
MAX CUT is smaller, the cutting volume each time is smaller, and the arc to
be processed is smoother, the processing time is longer; when the MAX
CUT is larger, the cutting volume each time is larger, and the arc to be
processed is rougher, the processing time is shorter.

A: Processing ZX and YZ planes

There are 8 processing methods as shown in the following figure when
arcs on ZX and YZ planes are processed.

Note: A flat-bottom milling cutter or an arc milling cutter can be used

for processing. When a flat-bottom milling cutter is used for processing the
arc, set the diameter of the cutter to be 0.000.

Chapter VII Error Compensation

Function
7.1 Linear error compensation
There is an error between the measured value and standard value of the
grating rule. If the two measurement curves are in an identical shape within the
grating ruler’s range of travel but not in coincidence, this is called a linear error.
Linear correction: To compensate the linear error so that the displayed
value is equal to the standard value.
Note: The linear error correction value is set by the installation personnel,
and must not be modified by the user at will, which otherwise would affect
measurement accuracy.

Step I: The interface of display system parameter setting is displayed. Set

the compensation mode of the corresponding axis to be “Linear
compensation”. (See Chapter 2.6 for the detailed setting method)

Step II: Input the linear error compensation value. There are two setting
methods:
1. To calculate the correction factor with a formula according to the
standard value and the digital display value.
2. Move the grating ruler to the standard value (the value shall be
the integral multiple of 10mm). After the current position is
confirmed, the system automatically calculate the
compensation factor.

Example: Install the standard measurement device (such as block gauge and
laser, etc.) at the X axis of the workbench. Move the grating ruler

42
corresponding to the workbench until 1000mm is displayed as the standard
measured value. At that time, the displayed value at the display is
999.98mm.

Method 1: Manually input the correction system. Calculate with the

following formula:
Correction factor S = (L-L')/(L/1000) mm/m
L---Actual measured length. Unit: mm
L'---Displayed value at the display. Unit: mm
S---When the correction factor mm/m is "+", lengthening is
indicated; when the correction factor mm/m is "-", shortening is
indicated.
Compensation scope: -1.500 mm/m~+1.500 mm/m
The actually-measured length of the machine tool workbench is
1000, while the finally displayed value at the display is 999.98.
S=(1000-999.98)/(1000/1000)=0.02 mm/m

After the correction factor is got through calculation, press the axis key.
Press key. Then the setting interface is displayed.

Method 2: Automatic calculation correction system

1. The interface for setting the linear
compensation tale is displayed. Move the
cursor to the “automatic setup” area at X axis.
2. Move the X-axis grating rule on the
workbench until 1000mm is displayed as
The standard measured value. At that time,
999.98mm is the displayed value at the display.
3. Press the button. The error correction is completed.

43
7.2 Non-linear error compensation
Attention: The non-linear compensation function can only be set
up in the status of metric display. After the setup is completed, metric
system or British system can be selected for display.
There are two methods for setting the starting point when making
non-linear error compensation at the display:
1. To make error compensation with the starting point as the
mechanical origin (Figure 1)
2. To make error compensation with the first actual zero point of the
grating ruler as the mechanical origin (Figure 2)

L: The distance of the effective range of the grating ruler
