4. Manual operation
4.1 Returning to reference point manually
CNC machine tool has specific mechanical position, which is called as reference point and for tool
exchange and coordinates setting. Generally, when the power supply is connected, the tool should be moved to
the reference point. This operation is also called as home operation, which will make the CNC system confirm
the origin of machine tool.
The home operation includes program and mechanical mode:
For program home, the action completes when the coordinates of machine tool are 0, and won’t check
whether origin switch is in position;
For mechanical home, the external home sensor switch is used to locate the origin of the machine tool;
two checking modes are available:
With the external sensor switch, the home operation completes when the sensing is successfully
repeatedly.
The external sensor switch is used as deceleration switch, the servo home is enabled as home signal after
sensing and then the sensing stops.
You can set the “Home mode” in [Parameter][Comprehensive Parameter], in which 0 (default) indicates
program and 1 indicates mechanical. You can also press [SBK] key in home mode to switch among
“Mechanical – Program – Mechanical…” quickly. This method doesn’t conflict with parameter setting. You
can select accordingly. To use servo home as the home signal, you need to set “Axis phase Z home enable” to
“1” in [Parameter][Axis Configuration] in mechanical home mode, and the setting will take effect in next
home checking.
Several methods are available for tool returning to reference point and the steps follow:
⑴Each axis returns to reference point separately
¾Press the mode switch key [Home] to select home operation;
¾Press the composite key [X-], [Y-], [Z-], [A-] in the numbers section to return the corresponding axis to reference point.
⑵The axes return to reference point simultaneously
¾Press the mode switch key [Home] to select home operation;
¾Press the [Start] key to return Z axis to reference point, and other axes return to reference point simultaneously. The
automatic home sequence can be configured in the parameters.
⑶Reset machine tool position
¾Press the mode switch key [Home] to select home operation;
¾In [Absolute Position] and [Coordinate System] screen, press [X], [Y], [Z], [A] respectively to show the value of
corresponding axis position, and then press the [Cancel] key to reset the machine tool position of current axis, i.e.
current point is used as machine tool origin. After this operation, the system considers it as a home action. Therefore,
when the program is running, the alarm of not home won’t occur. If you press by mistake, it will switch the screen and
cancel selection automatically.
⑷Reset relative position manually
¾Press the mode switch key [Manual] to select manual operation;
¾In [Relative Position] and [Coordinate System] screen, press [X], [Y], [Z], [A] respectively to show the value of
corresponding axis, and then press the [Cancel] key to reset the relative position of current axis.
)Note
The tool also can return to reference point according to program instruction, i.e. returning to reference point automatically.
0Caution:
Generally, the system will perform home operation after connecting the power supply. If the power fails while the machine
tool is moving, the system also will return to reference point when the power supply is connected again. Return to Z axis to
prevent tool and workpiece from colliding, and damaging tool, workpiece and clamp.

4.2 Continuous feeding manually
Press the keys on the operation panel or handwheel to move the tool along every axis.
The operation follows:
⑴Press the mode switch key [Manual] to select manual operation;
⑵Press composite keys [X+], [X-]; [Y+], [Y-]; [Z+], [Z-]; [A+], [A-] in numbers area to move the tool
along selected axis. The keypad follows:
In manual mode, 5# key can be used to switch the manual speed and rapid traverse speed. The rapid
traverse speed of every axis depends on comprehensive parameter 009-012 (rapid traverse speed setting). After
switching to rapid traverse speed, the manual speed of the position interface will be highlighted, while the
actual speed of the position interface is sampled from the moving speed of current axis. This value can truly
reflect the moving speed of current axis (unit: mm/min);
)Note
Only single axis motion is available in manual mode.
4.3 Single step feeding
Single step mode is similar to manual mode, the operations are same, but only moves a specified pulse
increment every time press the key.
The specific operation follows:
⑴Press the mode switch key [Handwheel/Single step] (this key is composite, and you can press it
repeatedly to switch the modes) to select the single step operation;
⑵Press composite keys [X+], [X-]; [Y+], [Y-]; [Z+], [Z-]; [A+], [A-] in numbers area to move the tool
for a fixed distance along the selected axis. This distance is controlled by four rates (1.000, 0.100, 0.010, 0.001)
(unit: mm). To select pulse increment, press Up (+) and Down (-) key in the [Position] interface.
4.4 Handwheel feeding
In handwheel mode, rotate the handwheel to make the machine perform single step or continuous motion.
Determine the feed by testing the handwheel signal of the handheld box. In handwheel mode, the feeding axis
and feeding unit are determined by the axis selection signal of the handheld box.
The handwheel feeding step follows:
⑴Press the mode switch key [Handwheel/Single step] to select handwheel operation;
⑵Rotate the dip switch on the handwheel to select handhweel axis (X, Y, Z, A);
⑶Rotate the increment dip switch on the handwheel to select the moving amount (0.1, 0.01, 0.001);
⑷Rotate the handwheel to move the machine tool. The tool moves certain distance every time you rotate
the handwheel for a scale. (For example, if you select X axis in step ⑵and select 0.01 in step ⑶, the tool
moves 0.01mm every scale). Rotate the handle continuously to move the machine tool on this axis
continuously.
)Note
The handwheel feeding mode controls only one coordinate axis every time; the faster the handwheel rotates, the faster the
machine tool moves.

Circle centered has two modes, which are three points and two points with specified radius; If the user
only types two coordinates in the option of workpiece boundary point and specifies one value for R, the system
will determine the circle center with two points and radius automatically; if the user types coordinates of three
points in the option of workpiece boundary point, the system will determine the circle center with three points
and shield R.
The centered step of three points arc follows:
¾Select the edit mode;
¾Press [Coordinates], [Coordinates Parameter] to enter the auxiliary parameters setting interface of the coordinate
system;
¾Move the cursor to desired position, enter new parameters and press [EOB];
¾Select handwheel or manual mode;

Arc centered validation
In the main menu, press [Monitor], [MDI] to enter the MDI interface, select edit mode, enter program
block G55G0X0Y0 (if coordinate system G55 is selected while tool setting), press [Start], [EOB], and the tool
moves to workpiece center automatically, indicating that three points arc centered properly.
The validation steps for other tool setting methods are same.
4.6.2 Tool regulator (M series)
Tool regulator principle:
The tool regulator uses external sensor switch to set the reference point for axis Z, which is similar to
home. After changing tool during processing or changing tool manually, transfer this function to automatically
check the Z value of current workpiece’s home.
Tool regulator usage
Before using the tool regulator, you need to set the parameters. In [Coordinate] menu, press [Coordinate
Parameter] to show tool setting parameters. After that, press [Tool Regulator] in the setting interface to execute
the tool regulator program according to specified parameters.
The action sequence of tool regulator follows
¾Return Z axis to mechanical home first, and then locate principal axis to X, Y coordinates of the tool regulator;
¾Tool regulator blows to start;
¾Z axis moves down, and retracts when touches tool regulator sensor switch, moves down at lower speed when the
sensor switch leaves, records the machine tool coordinates of current Z axis when touches the switch and assigns to the
Z coordinates of current selected coordinate system;
¾Tool regulator blows to turn off;
¾Z axis returns to home position.
