1.4 substantival explanation
When operate the NCH02, where will be a lot of English abbreviation, now we list all of
them for your kindly references:
FRO: Feeding adjust: During the operating process, the F value already set, and need to
adjust the current feeding speed, then we can adjust FRO value to realize it.
SRO: Spindle speed adjust: During the operating process, the S value already set, and need
to adjust the current spindle speed, then we can adjust SRO value to realize it :
Current Speed S#=setting S*SRO.
SRJ: speed adjust manually
During the operating process,as the manual speed already set,and we need to adjust the
current speed,and impossible to fix the value during it is working,then we can revise the SRJ
value to realize it.
Current manual speed FS#=Setting manual speed*SRJ.
F:Feedingspeed,the unit is mm/min.For example F=200,means every minute feeding
2000mm.
S: Spindle Speed. Unit is rad/min.For example S=20000,means 20000 revolution/Minute.

2.1 Device Power supply Solution
The power supply solution in the field of the Industrial automation is always very
complicated, there is a lot of the GND, now we descript the structure of the power supply as
below:
The power supply structure as the Figure 2-1,main power supply input and MPG module and
stepper control output module are common GND, Limited and Estop input module and Spindle
speed adjust module are common GND, between main power supply and output module there are
photoelectric isolation. The inputs of limited switch and Estop and so on are Common cathode,
inside of the device, there is GND as common-, no need to connect external power supply. Based
on the reference of output GND interface, output a 0-10V adjustable voltage to adjust the spindle
speed. The chassis is built with 220V to 48V DC supply to the DC brushless spindle and 4 step
motor driver.

Operation and Application
The basic operation is introduced in the front part of the keystroke. Here is not going to be
exhausted. Here we introduce the use of this product from the perspective of an initial user. The
first time we start the product, we first configure all the configuration items according to our actual
needs. Here we introduce the usage method, no longer describe the configuration items, and all the
configuration items are configured according to the customers' needs.
First of all, the system is started, our first step is to establish the m achine coordinate system ;
Manual of NCH02
the second step is probe, accurate zero; third step up the workpiece, the tip will move to zero
workpiece, and the workpiece coordinate reset; the fourth step is to load the G file; the above work
is finished, press START to start G code execution. The following sections describe these steps in
detail.
4.1 Establish machine coordinate system
As shown in Figure 4-1, the engraving machine schematic diagram is installed. Each axis is
equipped with a proximity switch. The limit and home share this switch. The X axis switch is
installed in the X-- position. The Y axis switch is installed in the Y++ position; the Z axis switch is
installed in the Z++ position. (here we test the prototype as a reference for installation, the actual
application of the customer can be selected according to the needs of the installation).

For the first time to use the system, we need to establish machine tool coordinate system,
that is, HOME.
After starting the system, we switch to the parameter settings page, "INPUT" sub-page, and
HOME configuration, according to our actual engraving machine configuration, as shown in
Figure 4-2. XYZ's HOME PIN is set to 3,4,5, LEVEL is set to 0, DIR X axis is set to 0, YZ
axis are set to 1. HBlength are all set to 10.

the next axis operation. The order of HOME operation in full axis is X, Y, A and Z.
4.2 Probe
The Probe can be configured as a fixed-point probe or a floating-point probe. Below we
describe 2 kinds of probe operation in detail.
4.2.1 Fixed-point probe
Fixed point probe is to fix the tool sensor in a fixed position of the engraving machine, and
every time the probe is processed, the spindle tip automatically moves to this fixed position for
tool setting. The installation position of the tool sensor is shown in reference Figure 4-4.

the XYZ axis mechanical coordinates. As shown in Figure 4-5, the plane center coordinates (X, Y,
Z) on the tool block are (30,30, -110).
Operation and Application
Secondly, we enter the OTHER sub page under CONFIG. As shown in Figure 4-6, we find
fixed-point tool block location configuration item, and configure related parameters of cutter
block as shown in table 4-1.

After the configuration is completed, we enter the main page and move the spindle to any
position. (we suggest that the Z axis of the tool tip is higher than the plane of the tool sensor). Press
+ , the system starts automatic probe. At this m oment, the system will automatically
move to the location of the set of tool sensor to automatically probe. After the probe is finished, the
system will automatically return to the just start position of the probe.
4.2.2 Floating-point probe
The floating probe means that the location of the tool sensor is not fixed at a certain
location, but is placed in any desired location. In this mode, we usually place the tool sensor on

the workpiece surface for floating-point probe. The position of the tool sensor is placed in
reference figure 4-8.
In the floating tool mode, there is no need to configure the position of the tool sensor. We
enter the OTHER subpage under CONFIG and set the probe related settings as shown in Ta ble

After completing the configuration we return to the main page, the tool sensor on the surface
of the workpiece, we only need to manually (MPG) move the spindle nose just above the tool
sensor, and then press + , the system will automatically start probe, after the
probe completion of the Z axis will be automatically lift off the tool sensor plane 10mm.
4.3 Workpiece zero point
After the probe is completed , the next step is confirm wor kpiece zero point, we want to
carve a product, first get the G code, to ensure the workpiece zero position of the G code file .
Some G code file set the workpiece center as the workpiece zero, some set a workpiece the
corner as the workpiece zero. Here is an example of a positive center on the surface of the
- 44 -

workpiece. Under the main page, use manual (MPG) to move the tip of the spindle to the center of
the workpiece surface and then presses + + to set axis coordinates to zero.
Operation and Application
Then move the Z axis out of the workpiece surface to the safety height. At this point, the workpiece
zero is confirmed.
4.4 Load and run G code
Under the main page, press to switch to file management page, adjust the knob to
select the files that need to be processed. As sh own in Figure 4-9, we selected the TEST2.TAP file.

After selecting a the file, press the confirmation key to automatically load the G code and
automatically return it to the MAIN page. As shown in Figure 4-10, the title bar file display section
has already appeared TEST2.TAP, indicating that the G code file is loaded successfully.
