1. Programming Basics

1.1. Introduction of CNC machine tool

CNC (Computer Numerical Controler) machine tool consists of CNC system, servo motor (or step

motor) drive, machine tool (including headstock, feed drive mechanism, worktable, tool holder,

electric control cabinet), etc. After CNC processing, the part program edited by the user will send

motion instructions and control instructions, while motion instructions drive the feeding of machine

tool through motor drive, and control instructions include principal axis start/stop, tool selection,

cooling, lubrication, etc. It achieves parts cutting through relative motion of tool and workpiece.

CNC programming is to write part processing program according to the dedicated programming

instructions of CNC system with the information such as part size, processing process, process

parameters, tool parameters, etc. CNC processing is that the CNC system controls the machine tool

to finish part processing according to the requirement of part processing program. The working

principle of CNC machine tool and the flow of CNC processing are shown in the figure below.

Analyze part drawing and confirm process
Write part program and enter CNC system
Check and run the program for testing
Set tool offset and coordinates
Run the processing program and process the part
Check the workpiece size, modify program or tool conpensation
Processing is finished and part is formed

1.2. Definition of coordinate axis

CNC machine tool is shown in Fig. 1-2-1

Tailstock seat Principal axis seat Tool Too holder

Fig. 1-2-1

The system uses the right angle coordinate system constituted with X axis and Z axis. X axis is
vertical to the principal axis, and Z axis is parallel to the principal axis. The direction to the
workpiece is negative, and the direction from the workpiece is positive.
According to the relative position of the tool holder and principal axis of the machine tool, CNC
lathe has front tool holder and rear tool holder. Same programming instruction has different motion
tracks in front tool holder and rear tool holder. This system can be used in the front tool holder and
rear tool holder of the CNC lathe. Seen from the figures below, the X directions of front and rear
tool holder coordinate systems are different, while the Z direction is same. The figures and
examples in this manual use front tool holder coordinate system to describe the application of
programming.

Fig. 1-2-2 Front tool holder coordinate system Fig. 1-2-3 Rear tool holder coordinate system

1.3. Machine tool coordinate system and mechanical home

Machine tool coordinate system is the reference of CNC for coordinate calculation, and is the
intrinsic coordinate system of the machine tool. The origin of the machine tool coordinate system is
mechanical reference or mechanical home.
Mechanical home is determined by the zero switch or home switch on the machine tool, which are

usually installed at the maximum travel in positive direction of X axis and Z axis. For mechanical
home operation, the system will set current machine tool coordinates to 0 after returned to

- 2 -

ADT-CNC4620 Programming Manual

mechanical home, and create a machine tool coordinate system with current position as the
coordinate origin.
Note: If the zero switch isn’t installed on the lathe, it isn’t possible to perform home operation.

1.4. Workpiece coordinate system and program home

Workpiece coordinate system is the right angle coordinate system set on the part drawing for
programming, which is also called floating coordinate system. When the part is installed on the
machine tool, set the absolue coordinates of the current position of the tool with G50 instruction
according to the relative position of tool and workpiece, and thus create workpiece coordinate
system in the system. The current position of the tool is the program home. Generally, Z axis and
principal axis of the workpiece coordinate system coincide, and X axis is in the head or end of the
part. The workpiece coordinate is always valid once created until replaced by new workpiece
coordinate system.

Part Bar stock

Fig. 1-4

In the figure above, XOZ is machine tool coordinate system, X1O1Z1 is the workpiece coordinate
system of X axis in the head of the workpiece, X2O2Z2 is the workpiece coordinate system of X
axis in the end of the workpiece, O is the mechanical home, A is tool tip, and the coordinates of A
in above three coordinate systems are as follows:

The coordinates of point A in machine tool coordinate system (X, Z);
The coordinates of point A in X1O1Z1 coordinate system (X1, Z1);
The coordinates of point A in X2O2Z2 coordinate system (X2, Z2);

Interpolation function

Interpolation is to control two or several axes to move simultaneously. The motion track complies
with fixed mathematical relationship, constitutes two-dimensional (plane) or three-dimensional
(space) profile, and interpolation is also called profile control. During interpolating, the motion axis
is called joint axis, the movement amount, direction and speed of which are controlled
simultaneously in the entire motion process, to form desired synthetic motion track.
Only control the motion end of one axis or multi-axis, do not control the track in the motion process,

- 3 -

ADT-CNC4620 Programming Manual

and the motion control mode is called point-position control.
The X axis and Z axis of this system are linked, which is two axes linked CNC system. This system
has linear, arc and thread interpolation function.
Linear interpolation: the synthetic motion track of X axis and Z axis is the straight line from the
start point to the end point.
Arc interpolation: the synthetic motion track of X axis and Z axis is arc from the start point to the
end point, the radius is specified by R, or the circle center is specified by I, K.
Thread interpolation: X axis, Z axis or two axes motion and principal axis rotation interpolation; F
specifies the pitch of threads, which is the movement (unsigned) of the axis (X or Z) that moves
longer when the principal axis rotates for a circle in the process of thread cutting. This system can
process metric straight thread, taper thread and end thread, and the machine tool must be installed
with principal axis encoder to process threads. If the encoder isn’t installed and it is threading, the
system can’t receive signals from the encoder and can’t perform other operations. (1000 wires
encoder or above is recommended for this system)

1.5. Absolute/relative coordinate programming

Two methods are available for specify the end position of the track during programming:
1: The end position of the track is expressed in absolute coordinates and it is called absolute
coordinate programming (instruction address uses X, Z).
2: The end position of the track is expressed with the coordinate difference of end point relative to
start point and it is called relative coordinate programming (instruction address uses U, W). The
negative value of relative coordinates represents running in negative direction of the axis, while the
positive value of relative coordinates represents running in positive direction of the axis.
This system allows expressing one axis of the end position with absolute coordinates and expressing
the other axis with relative coordinates in the same block. This method is called mixed
programming.

For example: A→B linear interpolation (as in Fig. 1-5)

Fig. 1-2-5

Absolute coordinates programming: G01 X200 Z50;
Relative coordinates programming: G01 U100 W-50;
Mixed coordinates programming: G01 X200 W-50; or G01 U100 Z50;

1.6. Conversion between imperial and metric system*

Set the unit to imperial or metric with G code (G20, G21).

System G code Minimum unit
Imperial G20 0.0001 inch
Metric G21 0.0001mm

The G code for imperial and metric switch should be placed in front of the program. Use

separate block instruction before setting the coordinate system. The unit system of the
following values changes according to the G code for imperial and metric switch.

(1) Feeding speed instruction value expressed with F.
(2) Instruction value related to position
(3) Compensation
(4) The value of one scale of the Handwheel pulse generator
(5) Movement of single step
(6) Part value of the parameter

Note:

1. When the system is electrified, the G code for imperial and metric switch is same as

before the power supply is cut off

2. In the program, do not change G20, G21

3. If the mechanical unit system is different from the input unit system, the maximum

error would be 0.5 of minimum movement unit, and the error won’t be accumulated.

4. When imperial input (G20) and metric input (21) are switched, the offset should

comply with the new setting of the input unit.

1.7. Program constitution

To complete automatic processing of the part, you need to write the part program (the program)
according to the instruction format of the CNC system, which will execute the program and
complete the controls such as machine tool feeding, principal axis start/stop, tool selection, cooling
and lubrication, and thus finish the part processing.

For example:

Fig. 1-7

- 5 -

ADT-CNC4620 Programming Manual

O0001; (program name)
G0 X100 Z50; (quickly locate point A)
M12; (clamp the workpiece)
T0101; (replace tool #1 and execute tool #1 offset)
M3 S600; (start the principal axis, and set the principal axis rotation to 600rpm)
M8 (coolant on)
G1 X50 Z0 F600; (approach point B at the speed of 600mm/min)
W-30 F200; (cut from point B to point C)
X80 W-20 F150; (cut from point C to point D)
G0 X100 Z50; (quickly back to point A)
T0100; (cancel tool offset)
M5 S0; (stop principal axis)
M9; (coolant off)
M13; (release workpiece)
M30; (program ends, principal axis/coolant off)
%

After above program, the tool will have a track of A→B→C→D→A.

1.8. General structure of program

The program consists of several block started with “OXXXX” (program name) and ended with “%”,
while block consists of several instruction words started with block number (can be omitted),
changed line with “CR” and ended with “LF”. The general structure of a program is shown in Fig.
1-3-2 below:

Instruction word Program name
Block end Block switch symbol
Block No. Block
Program end symbol

Fig. 1-8 General Program Structure

1) Program name

To identify the programs, every program has a name consists of instruction address O and
four digits later in the start of the program. This system can save up to 9999 programs,
and the program names can’t repeat.

2) Instruction word

Instruction word is the basic instruction unit for CNC system to complete the control
function. Instruction word consists of one English letter (instruction address) and later
digits (instruction value, signed or unsigned). Instruction address regulates the meaning of
following instruction value. In different combinations of instruction word, same
instruction address may have different meanings.

3) Block switch symbol, block No. and block

A program consists of several blocks and is executed in blocks. Generally, a block is
executed only the previous block has been executed. Blocks are separated with “;” or “*”,
and “;” is used in this manual. A block consists of several instruction words, and is started
with block No. and ended with “;” or “*”.
For example: block may have “/” symbol in the front, which is called block switch symbol

4) When the program is run automatically, if the switch function is enabled, the program will

execute next block automatically when running to this block. If the switch function isn’t
enabled, this block will be executed. The option of switch function is in the auxiliary interface
of main menu. This function won’t be saved after power off, and it is disabled by default after
initialization.

5) Block No.

N0000~N9999; the leading zero can be omitted. Block No. can be omitted, but the target
block for program call and switch must exist. The sequence of block No. may be random,
and the block No. in latter part doesn’t need to be larger than previous number. For the
convenience of reference, the line No. is usually arranged according to certain increment.
During manual editing, it is possible to determine whether insert line No. increment
automatically through No. 47 comprehensive parameter. The initialized value is 0, i.e. do
not insert line No. automatically.

6) Program end symbol

The program is started from program name and ended with “%”, which is the end symbol
of the program file. During communicating, “%” is the end symbol and start symbol.

1.9. Main program and subroutine

To simplify the programming, if same or similar processing track and control process need to be
used for several times, the program instructions of this part can be edited to independent program
for calling. The program that calls other programs is called as main program, and the program being
called (ended with M99) is called as subroutine. Both subroutine and main program occupy system
capacity and storage space. Subroutine also must have independent program name, and can be
called by any other main proram or run independently. When subroutine ends, it returns to the main
program and continues the execution. The system supports nine layers nesting, i.e. a subroutine can
call other subroutines, as shown in Fig. 1-9 below.

management parameter. MFUN(L)1 is not interlocked, and MFUNC(L)2 is
interlocked. M12 and M13 are released through macro program. The user can
customize. After parameter #022 is changed to User-Def, it is realized by writing the
macro program of M code.

Note 1: When the system is reset or stopped in emergency, the output states of M12

and M13 won’t change.

Note 2: chuck can be controlled with external input signal.

2.1.7. Lubricant control M32, M33

Instruction function: M32: lubricant pump open;

M33: lubricant pump closed
After the system is electrified, M33 is valid, i.e. M32 output is invalid. Execute M32,
M32 output is valid, and lubricant pump opens; execute M33, cancel M32 output, and
lubricant pump clodes; lubricant output port is specified by #075 port parameter; the
default option is OUT5.
Note 1: when the system is stopped in emergency, M32 output is invalid;

Note 2: M33 doesn’t have corresponding output signal; cancel M32 output when M33
is executed;

Instruction format: M00 or M0
Instruction function: after other instructions of current block are executed, the program

pauses. Press the cycle start key to run next block.

2.1.9. Program running ends and return to program beginning M30

Instruction format: M30
Instruction function: after other instructions of current block are executed, the program

stops automatically, executes M05, M09, and the processing pieces increase by 1.
The cursor returns to the beginning of the program.

2.2. Programmable I/O instructions

2.2.1. Programmable input instruction M88

Instruction function: the user defines the function of standby input point.
Instruction format:M88 Pxx Lx Qxxxx
P is used to specify the value range of output port number 0-23.
L is used to specify the valid input level, “1” is high voltage level and “0” is low voltage level.
Q is used to specify the testing time in the unit of ms.
Note 1: if specified voltage level isn’t detected in the time specified by Q instruction, the alarm
prompts “abnormal program termination error”.
Note 2: if Q instruction isn’t specified, the system will always wait for input signal by default,

and won’t execute next instruction until the signal is valid.

Note 3: if the specified port isn’t in the range 0-23, the alarm prompts “specified port number

error”.

Note 4: if P instruction isn’t written, the alarm prompts “specified port number error”.

2.2.2. Programmable output instruction M89

Instruction function: the user defines the function of standby output point.
Instruction format: M89 Pxx Lx
P is used to specify the value range of output port number 0-23.
L is used to specify the valid output level, “1” is high voltage level and “0” is low voltage level.
Note 1: if the specified port isn’t in the range 0-23, the alarm prompts “specified port number

error”.

Note 2: if P instruction isn’t written, the alarm prompts “specified port number error”.

2.3. Principal axis function (S instruction)

S instruction consists of instruction address S and later digits, and is used to control the

rotation of principal axis.

ADT-CNC4620 Programming Manual

Gear position control: S _1~16 principal axis rotation is controlled by switching 16-gear BCD
code. In gear position control mode, #061 comprehensive parameter must be 1, and port
parameters #070~073 specify the output port of gear position.

Analog control: S _0~maximum rotation; in analog control mode, #061 comprehensive
parameter must be 0, and it is required to set the maximum principal axis rotation of parameter #20.
The controller will output 0~10V analog voltage on principal axis port XS8 according to this
parameter. If S instruction and the instruction word that executes moving function are in the same
block, motion instruction and S instruction are executed at the same time.

2.3.1. Principal axis rotation switching control

Instruction format: S_1~16.

Instruction function: 16 gear BCD coding position control.

2.3.2. Principal axis rotation analog voltage control

Instruction format: M03 (M04) S____

Instruction function: set principal axis rotation, the system outputs 0~10V analog voltage to

control principal axis servo or inverter, achieve stepless speed change, and the
value of S instruction is saved after power off.

For example:

Program:
O0001; (program name)
M3 S300; (principal axis forward rotation)
G0 X100 Z50; (quickly move to point A)
G0 X50 Z0; (quickly move to point B)
G1 W-30 F200; (cut from point B to point C)

X80 W-20 F150; (cut from point C to point D)
G0 X100 Z50; (quickly back to point A)
M30; (program ends, principal axis/coolant off)

2.3.3. Principal axis rate

If principal axis rotation analog voltage control mode is valid, the actual rotation of the principal axis
can be adjusted in 10%~150% instruction rotation range by 15 levels (change 10% every level) with
