2 GENERAL WARNINGS AND CAUTIONS
Warning
1. Never attempt to machine a workpiece without first checking the operation of the machine.
Before starting a production run, ensure that the machine is operating correctly by performing a trial run using, for
example, the single block, feedrate override, or machine lock function or by operating the machine with neither a
tool nor workpiece mounted. Failure to confirm the correct operation of the machine may result in the machine
behaving unexpectedly, possibly causing damage to the workpiece and/or machine itself, or injury to the user.
2. Before operating the machine, thoroughly check the entered data. Operating the machine with incorrectly
specified data may result in the machine behaving unexpectedly, possibly causing damage to the workpiece and/or
machine itself, or injury to the user.
3. Ensure that the specified feedrate is appropriate for the intended operation. Generally, for each machine, there is
a maximum allowable feedrate. The appropriate feedrate varies with the intended operation. Refer to the manual
provided with the machine to determine the maximum allowable feedrate. If a machine is run at other than the
correct speed, it may behave unexpectedly, possibly causing damage to the workpiece and/or machine itself, or
injury to the user.
4. When using a tool compensation function, thoroughly check the direction and amount of
Compensation. Operating the machine with incorrectly specified data may result in the machine behaving
unexpectedly, possibly causing damage to the workpiece and/or machine itself, or injury to the user.
5. The parameters for the CNC and PMC are factory-set. Usually, there is not need to change them. When,
however, there is not alternative other than to change a parameter, ensure that you fully understand the function of
the parameter before making any change. Failure to set a parameter correctly may result in the machine behaving
unexpectedly, possibly causing damage to the workpiece and/or machine itself, or injury to the user.
6. Immediately after switching on the power, do not touch any of the keys on the MDI panel until the position
display or alarm screen appears on the CNC unit. Some of the keys on the MDI panel are dedicated to
maintenance or other special operations. Pressing any of these keys may place the CNC unit in other than its
normal state. Starting the machine in this state may cause it to behave unexpectedly.
7. The operator’s manual and programming manual supplied with a CNC unit provide an overall description of the
machine’s functions, including any optional functions. Note that the optional functions will vary from one
machine model to another. Therefore, some functions described in the manuals may not actually be available for a
particular model. Check the specification of the machine if in doubt.
8. Some functions may have been implemented at the request of the machine–tool builder. When using such
functions, refer to the manual supplied by the machine–tool builder for details of their use and any related
cautions.
NOTE: Programs,parameters, and macro variables are stored in nonvolatile memory in the CNC unit.
Usually, they are retained even if the power is turned off. Such data may be deleted inadvertently, however, or it
may prove necessary to delete all data from nonvolatile memory as part of error recovery.To guard against the
occurrence of the above, and assure quick restoration of deleted data, backup all vital data, and keep the
backup copy in a safe place.

3 WARNINGS AND CAUTIONS RELATED TO PROGRAMMING
This section covers the major safety precautions related to programming. Before attempting to perform
programming, read the supplied operator’s manual and programming manual carefully such that you are fully
familiar with their contents.
Warning
1.Coordinate system setting
If a coordinate system is established incorrectly, the machine may behave unexpectedly as a result of the program
issuing an otherwise valid move command.
Such an unexpected operation may damage the tool, the machine itself, the workpiece, or cause injury to the user.
2. Positioning by nonlinear interpolation
When performing positioning by nonlinear interpolation (positioning by nonlinear movement between the start
and end points), the tool path must be carefully confirmed before performing programming. Positioning involves
rapid traverse. If the tool collides with the workpiece, it may damage the tool, the machine itself, the workpiece,
or cause injury to the user.
3. Function involving a rotation axis
When programming polar coordinate interpolation or normal–direction (perpendicular) control, pay careful
attention to the speed of the rotation axis. Incorrect programming may result in the rotation axis speed becoming
excessively high, such that centrifugal force causes the chuck to lose its grip on the workpiece if the latter is not
mounted securely. Such mishap is likely to damage the tool, the machine itself, the workpiece, or cause injury to
the user.
4. Inch/metric conversion
Switching between inch and metric inputs does not convert the measurement units of data such as the workpiece
origin offset, parameter, and current position. Before starting the machine, therefore, determine which
measurement units are being used. Attempting to perform an operation with invalid data specified may damage
the tool, the machine itself, the workpiece, or cause injury to the user.
5. Constant surface speed control
When an axis subject to constant surface speed control approaches the origin of the workpiece coordinate system,
the spindle speed may become excessively high. Therefore, it is necessary to specify a maximum allowable speed.
Specifying the maximum allowable speed incorrectly may damage the tool, the machine itself, the workpiece, or
cause injury to the user.
6. Stroke check
After switching on the power, perform a manual reference position return as required. Stroke check is not possible
before manual reference position return is performed. Note that when stroke check is disabled, an alarm is not
issued even if a stroke limit is exceeded, possibly damaging the tool, the machine itself, the workpiece, or causing
injury to the user.
7. Absolute/incremental mode
If a program created with absolute values is run in incremental mode, or vice verse, the machine may behave
unexpectedly.
8. Plane selection
If an incorrect plane is specified for circular interpolation, helical interpolation, or a canned cycle, the machine
may behave unexpectedly. Refer to the descriptions of the respective functions for details.
-Shenzhen Guanhong Automation Co.,Ltd.- SZGH-CNC1000MDb Series
IV
9. Compensation function
If a command based on the machine coordinate system or a reference position return command is issued in
compensation function mode, compensation is temporarily canceled, resulting in the unexpected behavior of the
machine. Before issuing any of the above commands, therefore, always cancel compensation function mode.
4 WARNINGS AND CAUTIONS RELATED TO HANDLING
This section presents safety precautions related to the handling of machine tools. Before attempting to
operate your machine, read the supplied operator’s manual and programming manual carefully, such that you are
fully familiar with their contents.
Warning
1. Manual operation
When operating the machine manually, determine the current position of the tool and workpiece, and ensure that
the movement axis, direction, and feedrate have been specified correctly. Incorrect operation of the machine may
damage the tool, the machine itself, the workpiece, or cause injury to the operator.
2. Manual reference position return
After switching on the power, perform manual reference position return as required. If the machine is operated
without first performing manual reference position return, it may behave unexpectedly. Stroke check is not
possible before manual reference position return is performed.
An unexpected operation of the machine may damage the tool, the machine itself, the workpiece,or cause injury to
the user.
3. Manual handle feed
In manual handle feed, rotating the handle with a large scale factor, such as 100, applied causes the tool and table
to move rapidly. Careless handling may damage the tool and/or machine, or cause injury to the user.
4. Disabled override
If override is disabled (according to the specification in a macro variable) during threading or other tapping, the
speed cannot be predicted, possibly damaging the tool, the machine itself, the workpiece, or causing injury to the
operator.
5. Origin/preset operation
Basically, never attempt an origin/preset operation when the machine is operating under the control of a program.
Otherwise, the machine may behave unexpectedly, possibly damaging the tool, the machine itself, the tool, or
causing injury to the user.
6. Workpiece coordinate system shift
Manual intervention, machine lock, or mirror imaging may shift the workpiece coordinate system. Before
attempting to operate the machine under the control of a program, confirm the coordinate system carefully. If the
machine is operated under the control of a program without making allowances for any shift in the workpiece
coordinate system, the machine may behave unexpectedly, possibly damaging the tool, the machine itself, the
workpiece, or causing injury to the operator.
7. Software operator’s panel and menu switches
Using the software operator’s panel and menu switches, in combination with the MDI panel, it is possible to
specify operations not supported by the machine operator’s panel, such as mode change, override value change,
and jog feed commands.
Note, however, that if the MDI panel keys are operated inadvertently, the machine may behave unexpectedly,
possibly damaging the tool, the machine itself, the workpiece, or causing injury to the user.

V
8. Manual intervention
If manual intervention is performed during programmed operation of the machine, the tool path may vary when
the machine is restarted. Before restarting the machine after manual intervention, therefore, confirm the settings of
the manual absolute switches, parameters, and absolute/incremental command mode.
9. Feed hold, override, and single block
The feed hold, feedrate override, and single block functions can be disabled using custom macro system variable
#3004. Be careful when operating the machine in this case.
10. Dry run
Usually, a dry run is used to confirm the operation of the machine. During a dry run, the machine operates at dry
run speed, which differs from the corresponding programmed feedrate. Note that the dry run speed may
sometimes be higher than the programmed feed rate.
11. Cutter and tool nose radius compensation in MDI mode
Pay careful attention to a tool path specified by a command in MDI mode, because tool nose radius compensation
is not applied. When a command is entered from the MDI to interrupt in automatic operation in tool nose radius
compensation mode, pay particular attention to the tool path when automatic operation is subsequently resumed.
Refer to the descriptions of the corresponding functions for details.
12. Program editing
If the machine is stopped, after which the machining program is edited (modification, insertion, or deletion), the
machine may behave unexpectedly if machining is resumed under the control of that program. Basically, do not
modify, insert, or delete commands from a machining program while it is in use.
5 WARNINGS RELATED TO DAILY MAINTENANCE
WARNING
1. Memory backup battery replacement
When replacing the memory backup batteries, keep the power to the machine (CNC) turned on, and apply an
emergency stop to the machine. Because this work is performed with the power on and the cabinet open, only
those personnel who have received approved safety and maintenance training may perform this work.
When replacing the batteries, be careful not to touch the high–voltage circuits (marked and fitted with an
insulating cover).Touching the uncovered high–voltage circuits presents an extremely dangerous electric shock
hazard.
NOTE:The CNC uses batteries to preserve the contents of its memory, because it must retain data such as
programs, offsets, and parameters even while external power is not applied. If the battery voltage drops, a low
battery voltage alarm is displayed on the machine operator’s panel or screen. When a low battery voltage alarm
is displayed, replace the batteries within a week. Otherwise, the contents of the CNC memory will be lost. Refer
to the maintenance section of the operator’s manual for details of the battery replacement procedure.
2. Absolute pulse coder battery replacement
When replacing the memory backup batteries, keep the power to the machine (CNC) turned on, and apply an
emergency stop to the machine. Because this work is performed with the power on and the cabinet open, only
those personnel who have received approved safety and maintenance training may perform this work. When
replacing the batteries, be careful not to touch the high–voltage circuits (marked and fitted with an insulating

cover). Touching the uncovered high–voltage circuits presents an extremely dangerous electric shock hazard.
NOTE:The absolute pulse coder uses batteries to preserve its absolute position. If the battery voltage drops, a
low battery voltage alarm is displayed on the machine operator’s panel or screen. When a low battery voltage
alarm is displayed, replace the batteries within a week. Otherwise, the absolute position data held by the pulse
coder will be lost.
3. Fuse replacement
For some units, the chapter covering daily maintenance in the operator’s manual or programming manual
describes the fuse replacement procedure.
Before replacing a blown fuse, however, it is necessary to locate and remove the cause of the blown fuse. For this
reason, only those personnel who have received approved safety and maintenance training may perform this work.
When replacing a fuse with the cabinet open, be careful not to touch the high–voltage circuits (marked and fitted
with an insulating cover).
Touching an uncovered high–voltage circuit presents an extremely dangerous electric shock hazard.
Special Attention:
1. All the functions of A axis & B axis on system are effective when configure with fourth axis & fifth axis.
2. When use this system for the first time, please read carefully all the details of each chapter so as to make it
work more efficiency and safer.
3. The “Run” button on the panel of system can be used when debugging (P9 in Other parameter to set
“Valid” or “Invalid”), must plus an external “Run” button when fitting system, otherwise may cause accident
because of the life of button!!!So the system prohibits using the “Run” button of panel for long times,
otherwise the consequences has nothing to do with my company.
4. Don’t plug & insert connectors when system is on power.
5. We will use some short name to stands for parameter number. For example: P -- Parameter , P1 stands for
the No.1 parameter .Example: P9-D6,also No.9 parameter, No.7 bit from right to left side.
6. There are some bit parameters on CNC system, different bit parameters have different means, some bit
parameters are for inner system,don’t change these bits parameter we don’t explain,keep same as ex-factory
set.

Chapter 2 Programming
CNC milling System is highly effective automation equipment according to programmed
program to process workpiece. Programming is using the CNC system control language according
to the requirement and drawing of the workpiece to describe the processing trajectory and the
assistant action. Ideal system not only could promise process qualified workpiece, but also make the
functions of milling reasonable application and fully use, so it is very important to programming,
this chapter will introduce many kinds of instructions and usage of CNC program, please read
carefully.

Expansion of controlled axis(total)
Up to 5(X, Y, Z, A,B/C)
Table 2-1-1
Program Segment:a complete command line consisted of instruction and data .
Program: is a congregation of program segment by machining logic structure in order to
complete the machining of workpiece.
Machine Coordinate System: The establishment of coordinate is based on machine’s zero
point.The milling machine coordinate axis and its direction should follow to "ISO841" standard.
The method as follow: Through right hand rule we can make the program coordinate, The Z axis
is parallel as spindle, The X axis is horizontal, The Y axis is determined by right hand rule. The A,
B, C are rotated axis or assistant axis which parallel as X,Y,Z axis. Furthermore, The coordinate
axis direction is the increasing workpiece dimension direction.
When without set work coordinate, take machine coordinate as work coordinate.
Working Coordinate System: Work piece processing uses the coordinate system is called as
the work piece coordinate system, it is set by CNC. The work piece coordinate system could change
to move its zero point.
Set the workpiece coordinates:
1.Use G54 ~ G59: Use coordinate parameters to set 6 workpiece coordinate system.
2.G52: Set a value behind G52 to set the workpiece coordinate system in program.
With absolute value instruction ,it must use the above method to establish the work piece
coordinate system.

Local coordinate system: Set local coordinate system of workpiece coordinate system in order
to programme easily when programming in workpiece coordinate system.
Absolute Programming:coordinates data of programming mode based on established absolute
coordinate system.Absolute coordinate value is corresponding to homing point of coordinate system.
It is settlements by “G90 X_Y_Z_A_”.
Relative Programming(increment programming)：It is distance and direction of operation end
point ,compared with starting point.It is settlements by “G90”.
Mode Instruction：The instruction which can remain the function in the program.It works both
in this program and program in the future.
In the same operation, there may be several mode instruction, such as M03(spindle
clockwise),M04(spindle counter clockwise),M05(spindle stop).They are all mode used to control
spindle.The mode of same kind are categorized into one mode group.At any time it must be one of
them,and there is only one of them.The original chosen mode is called mode origin.In the above
mode group,M05 is such a mode origin .
Suspending Mode(destroying mode): It is instruction which can turn mode instruction into mode
origin or destroy the mode.Such as M20(program ending instruction),meaning the end of operation
and returning to original status.
Non-Mode instruction：It is the instruction which has no function to store,and only works in the
segment of program.
2.1.1 Tool Movement Along Workpiece Parts Figure Interpolation
