SafetySafetySafetySafety PrecautionsPrecautionsPrecautionsPrecautionsThis section enumerates the safety precautions for protecting the user and preventing

damage to the machine. Read the contents of this part thoroughly before attempting to use

the machine.

1.1.1.1. OperationOperationOperationOperation ManualManualManualManual

While this operation manual supplied with an numerical control unit provides an overall

description of the machine’s functions, some functions are specific for that machine alone

and may not be available for another model. Check the specification of the machine if in

doubt as to its machine-specific functions.

2.2.2.2. WorkingWorkingWorkingWorking EnvironmentEnvironmentEnvironmentEnvironment

� Working temperature: 0°C - 45°C (32°F to 113°F), no freezing

� Temperature variation: less than 1.1°C/min (2°F/min)

� Humidity: below 90% Relative Humidity, non-condensing and without frost

Less than 75% Relative Humidity is more desirable.

95% Relative Humidity is for the shot-term use (within one month)

� Storage: –20°C to 60°C (-4°F to 140°F), non-condensing and without frost.

� Environment: All devices should be placed indoors and away from sunshine, dust,

eroding gases and moisture.

� Height: 1000 meter above the sea level (2000meter)

� Vibration: Impact during transportation or other situations should be less than 5.9m/s

(0.6g) for vibrations in the range between 10 to 60Hz.

3.3.3.3. GroundingGroundingGroundingGrounding

Correct grounding is critical for the numerical control unit and other electrical devices.

� No grounding or incorrect grounding may injure the operator or damage components

of the numerical control devices.

� If the devices are not correctly grounded, inductive interference from electric motors

and appliances can lead to errors and unexpected results.

Safety Precautions

vi

4.4.4.4. PowerPowerPowerPower

Electronic control tank is to supply the power for the milling machine. Please refer to

the machine installation instruction manual.

5.5.5.5. FilterFilterFilterFilter

Filters are used on cooling fans to prevent dust from entering into devices. However, it

would prevent adequate cooling if the filters become clogged. It is recommended that

the user clean the filters every three months. In dusty environments such as wood

routers, clean the filters more often.

6.6.6.6. Non-OperationNon-OperationNon-OperationNon-Operation

After a long period of non-operation, numerical control devices should be cleaned and

dried. Also check the wiring and ground connections. Once power is resumed after

non-operation, observe the operation for several hours to make sure there is no

unexpected behavior.

7.7.7.7. ManualManualManualManual DataDataDataData InputInputInputInput (MDI)(MDI)(MDI)(MDI) panelpanelpanelpanel

After turning on the power immediately, do not touch any of the keys on the Manual

Data Input (MDI) panel until the position display or alarm screen appears on the

numerical control unit. Since some of the keys on the MDI panel are dedicated to the

maintenance or other special operations, pressing any of these keys may prevent the

numerical control unit from entering its normal state. Starting the machine in the wrong

state may cause unexpected motion or behavior.

8.8.8.8. CheckCheckCheckCheck

Before operating the machine, thoroughly check the entered data, including parameters,

program and settings. Operating the machine with incorrectly specified data may also result

in unexpected motion or behavior that can damage the workpiece, damage the machine, or

injure the operator.

Safety Precautions

vii

9.9.9.9. TrialTrialTrialTrial RunRunRunRun

Never machine a workpiece without checking the machine's status at first. Before using

the machine for a production run, make sure that the machine operates correctly by

doing a trial run including, for example, a single block with a feedrate override or a

machine lock function. Another possibility is to do the trial run without a tool or

workpiece mounted. Failure to confirm the correct operation with a trial run may result

in unexpected motion or behavior that can damage the workpiece, damage the machine,

or injure the operator.

10.10.10.10. FeedrateFeedrateFeedrateFeedrate

Ensure that the specified feedrate is appropriate for the intended operation. The

appropriate feedrate varies with the operation. Generally each machine has a maximum

allowable feedrate found in the machine's operation manual. If a machine is run at other

than the correct feedrate or if the maximum allowable feedrate is exceeded, unexpected

motion or behavior may result that can damage the workpiece, damage the machine, or

injure the operator.

11.11.11.11. ToolToolToolTool compensationcompensationcompensationcompensation functionfunctionfunctionfunction

When using the tool compensation function, thoroughly check the direction and amount

of compensation for each tool. Operating the machine with incorrectly specified data

may produce unexpected motion or behavior that can damage the workpiece, damage

the machine, or injure the operator.

12.12.12.12. ParametersParametersParametersParameters

Usually, there is no need to change the factory-set parameters of the NC unit and PMC.

However, when there is no choice other than to change a parameter, be sure you fully

understand the function of the parameter before making any change. Failure to set a

parameter correctly may produce unexpected motion or behavior that can damage the

workpiece, damage the machine, or injure the operator.

By pressing these keys, the spindle speed, rapid traverse speed and feed rate (machining

speed) can be adjusted. The first row controls the spindle speed, the second row controls the

rapid traverse speed and the bottom row controls feed rate.

Figure 1.21 Speed Adjustment Keys

These keys work by adjusting the speed relative to a “base” speed. Different modes

(Automatic, Single Block and Manual) may have different base speeds. The base speed is

set by the G-code program or the parameter.

For each row, pressing the center key sets the speed at 100% of the base speed; the LED

light in the key’s upper-left corner is lit to signify that the machine is running at 100 percent

of the base speed. Pressing the minus (-) key, decreases the base speed by a fixed percent;

pressing the plus (+) key, increases the base speed by a fixed percent. Below is an example

where the speeds are changed by 2%:

These nine keys are to select the desired axis and the direction of motion in various modes.

These keys only function in Manual Mode, INC Mode and Reference Mode. The LED light

in the upper-left corner specifies which axis or direction is selected.

Figure 1.22 Axis Operation Keys

Table 1 7 Description of Axis Operation Keys


In INC mode or Manual Mode, the tool moves the X axis in the positivedirection while +X is pressed, and in the negative direction while –X ispressed. In Reference mode, pressing the +X key homes the X axis (finds themachine reference on the X axis).

In INC mode or Manual Mode, the tool moves the Y axis in the positive directionwhile +Y is pressed, and in the negative direction while –Y is pressed. InReference mode, pressing the +Y key homes the Y axis (finds the machinereference on the Y axis).

In INC mode or Manual Mode, the tool moves the Z axis in the positivedirection while +Z is pressed, and in the negative direction while –Z ispressed. In Reference mode, pressing the +Z key homes the Z axis (findsmachine reference on the Z axis).

The 4TH axis is only valid for servo-driven spindle mills. In INC mode orManual Mode, the spindle moves in the positive direction while +4TH ispressed and in the negative direction while –4TH is pressed. In Referencemode, pressing the +4TH key homes the spindle (finds the spindle reference).

This key speeds up tool motion in Manual mode. It must be pressed inconjunction with one of the Axis keys.

2222 SettingSettingSettingSetting UpUpUpUpBefore machining a part, the operator needs to set up the machine coordinates and the

workpiece coordinates, define tools parameters and other machine preparations.

The general setup procedure includes six steps:

1) Power On

2) Reset

3) Reference home (point approach)

4) Define software limits

5) Set tool data

6) Set workpiece coordinates

The first three steps are always necessary once the machine is powered on. Step 4 is

necessary only when the machine is set up for the first time. Step 5 is done for each tool

cutter before it is used to cut the parts. Step 6 is done each time if a new program is used.

Let’s go through these steps in detail:

2. Setting Up

24

2.12.12.12.1 Power-onPower-onPower-onPower-onThe procedure to turn the power on:

1) Check and make sure the machine is safe to run.

2) Press down the Emergency Stop button on MCP.

3) Turn on the power of the machine (usually located in back of the machine and/or

beneath the control panel).

4) Make sure the fans run normally

5) Make sure the lamps on the machine control panel have been lighted on.

2. Setting Up

25

2.22.22.22.2 Reset/EmergencyReset/EmergencyReset/EmergencyReset/Emergency StopStopStopStopAfter Power-on, reset the control unit by twisting the Reset Button clockwise. Resetting the

servo and spindle power is to enable the machine. Pushing the RESET button down

generates an Emergency stop event and disables the servo and spindle.

Figure 2.1 Emergency Stop

Feed motion from the axis motors and the spindle motor will stop immediately when the

Emergency Stop (ES) button is pressed. This button can be used:

� when there is a machine malfunction

� before turning the power on or off

Once the ES button is pressed, the system enters into the “ES Mode”. In this mode, no

operation except reset is allowed. After curing the cause of the machine malfunction, or the

machine is turned on, the emergency stop button can be released by the RESET operation

(twisting the ES button clockwise).

2.32.32.32.3 HomingHomingHomingHoming (Reference-point(Reference-point(Reference-point(Reference-point Approach)Approach)Approach)Approach)In homing (sometimes called reference point approach), there is a reference point for each

axis. These reference points are used to set up the machine’s coordinate system. Since the

axis’ original positions are the same as the previous time, homing should always be

performed once the machine is turned on.

The following figure shows a diagram of a typical axis homing. The present location in red

is a distance from the Origin. When the axis homes, the axis motion moves the present

location toward the origin until it touches the Reference Switch (RSW).

Origin

Reference Switch (RSW)

Motion Axis

Present location

Figure 2.2 Reference Position

As it is shown in Figure 2.3, it is roughly located near the origin. Next, machine control

moves the tool very slowly until the “home signal” encoder signal is triggered. This is the

exact location of the origin, accurate to the resolution of the encoder.

For proper homing, the direction for reference point approach must first be defined for each axis.

This setup is done once only in the parameters (see setting Parameters, Chapter 10).

2. Setting Up

27

The sequence for homing is as follows (Figure 2.4). First switch the mode to Reference

mode by pushing the Home key on the control panel. Next, press “+X” to home the X axis,

and press “+Y” to home the Y axis. At last, press “+Z” to home the Z axis.

Switch the mode to home mode by pressing the home key on the MCP.

Press “+X” to approach reference point of x axis

Press “+Z” to approach reference point of z axis

Press “+Y” to approach reference point of y axis

2.42.42.42.4 HardwareHardwareHardwareHardware LimitLimitLimitLimit andandandand SoftwareSoftwareSoftwareSoftware LimitLimitLimitLimitEach axis has a hardware limit and a software limit on each end of the axis. In the figure

below, the hardware switches (shown in black) are at the extreme left and right of the axis.

Software switches (shown in white) are interior to the hardware switches. The limits on one

end of the axis are the negative limits, those at the other end are the positive limits. By

convention, the positive X axis moves the workpiece left, the positive Y axis moves the

workpiece in the cross direction, while the positive Z axis moves the cutter away from the

workpiece along the spindle (i.e., milling) axis.

Figure 2.5 Hardware Limit and Software Limit

When the axis is commanded to go beyond these limits (over-travel), first the software

switch will be encountered (Figure 2.5). At this point the motion ceases and no further

motion in this direction is permitted.

The tool can be retrieved from a software over-travel by using manual or incremental

commands to move the tool back towards the middle of the axis. The sequence of releasing

the software over-travel is as follows:

1) Press the mode key: Manual mode key or Automatic mode key

2) Press the over-travel release key until the system is reset.

3) Move the axis out of over-travel

Software limits are defined for each axis using machine parameters. With the software limits

set, the control unit can decelerate and stop the tool safely before the tool gets to the

hardware limit switches.

2. Setting Up

If the tool goes beyond the software limit, the hardware limit switch is encountered. This

can occur if the software switches are not set properly, or if the tool is moving too fast to

stop when the software limit is reached.

2.52.52.52.5 SettingSettingSettingSetting ToolToolToolTool DataDataDataDataThere are two kinds of tool data (magazine list and tool features) to be registered before the

tool can be used to cut a workpiece. Magazine list and tool features are used for registering

tool numbers, tool position in ATC, length and radius, life expectancy etc. Each tool is

identified by its own tool number (T number).

are used to simplify the programming.

User can define six workpiece coordinates with G54~G59. To use these six workpiece

coordinates, user needs to define the offset of their origin to the machine coordinates’ origin.

The sequence of setting the coordinate system is as follows:

1) Main menu F5 [SETT]�F1 [W.C.S]

2) Select the W.C.S you want to set the offset by F1~F8

3333 ManualManualManualManual OperationOperationOperationOperationManual Operation (MANMANMANMAN) uses various input devices to carry out operations much like

those of a manual milling. While the internal computer is actually controlling the machine

tool during these operations, they are familiar to an operator that has machined parts on a

manual milling.

MANMANMANMAN operations are primarily used for setting up parts. In MANMANMANMAN mode, the cutter can be

moved into position near the workpiece where sample facing and turning cuts can be made

for setting the workpiece reference. In addition the cutter can be moved out of the way to get

access to the part for measuring. For an experienced milling operator that has little or no

experience on an NC milling, these operations are a good place to start. You can understand

how familiar operations are implemented on an NC machine.

moving the cutting tool toward the workpiece use a minus key (-X, -Y, -Z, -4TH). For

moving the cutting tool away from the workpiece use a plus key (+X, +Y, +Z, +4TH).

The tool will continue to move at a fixed speed along the selected axis so long as the

key is pressed. The tool motion stops when the axis key is released.

� The tool moves at a fixed speed along the selected axis. This fixed speed is called JOG

feedrate. The JOG feedrate is a fixed fraction of the rapid traverse rate. The factory

default JOG feedrate is one third (1/3) of the rapid traverse speed. For example, if the

rapid traverse feedrate were set at 600 inch/min, the JOG feedrate would be 200

inch/min using the factory default setting. Moreover, this default JOG feedrate for each

axis can be set by the axis parameter (See Chapter 10).

Incremental feed is used to move an axis at a fixed increment of travel. In INC mode, the

cutting tool moves at the JOG feedrate. Pressing an axis key in incremental or INCINCINCINC mode,

moves the cutting tool one increment in that axis and direction.

Figure 3.7 shows the feed axis keys in incremental mode.

This key moves the X axis one step in the positivedirection (awayawayawayaway fromfromfromfrom the workpiece)

Figure 3.7 Feed Axis Keys in Incremental Mode

� For each press of the feed axis keys: +X, -X, +Y, -Y, +Z or -Z, the tool cutter moves a

certain distance. If your milling has a fourth axis (4TH axis), you can also press the

+4TH or -4TH keys. To move the cutting tool toward the workpiece use a minus key

(-X, -Y, -Z, -4TH). For moving the cutting tool away from the workpiece use a plus key

(+X, +Y, +Z, +4TH).

� The distance is the number of minimum steps multiplied by the magnifier value. For

example, if the magnifier were set at 1 and you pressed the +X key twice, the distance

moved would be stepminimum221 =× . In inch units, that's a tenth of a thou, in

metric units that's 2 microns. But if the magnifier were set at 100, the distance moved

would be step minimum2002100 =× . In inch units, it moves ten thou (0.012inch),

in metric units it moves 200 microns (0.2mm).

As it is mentioned above, in incremental mode, pressing an axis key on the Machine Control

Panel moves the tool one step along the selected axis in the selected direction.

The step length is a “magnified” length. The distance moved in a step length is the

minimum step multiplied by the magnifier value:

magnifierstep minimumlengthstep ×=

� Minimum step

The “minimum step” is the shortest distance that an axis can move. The minimum step is a

certain rotation of the ball screw moving each axis. It is determined by the machine's

encoder. Depending on the number of steps on that axes' encoder, the step size is either in

inch or metric units. For an inch unit encoder, the minimum step is 50 millionths of an inch

(half a tenth of a thou). For a metric unit encoder, the minimum step is 1 micron (0.001

mm).

The four keys below (Figure 3.8) are the step length magnification in the INCINCINCINC mode.

Pressing any key changes the magnification of the corresponding distance. The minimum

4444 AutomaticAutomaticAutomaticAutomatic OperationOperationOperationOperationAutomatic (AUTOAUTOAUTOAUTO) operation is used to machine parts under program control. In an NC

machine tool, most production machining is done as an AUTOAUTOAUTOAUTO operation. In Automatic

mode, you can execute part programs automatically. If you are a manual milling operator, it

is the AUTOAUTOAUTOAUTO operations that will be most unfamiliar to you.

AUTOAUTOAUTOAUTO operation requires a program to execute. Several sample programs are already

included in the controller's memory. If you are a beginner, execute one of the sample

programs in AUTOAUTOAUTOAUTO mode. If you are an advanced NC operator, execute a program that you

have written yourself.

Automatic operation includes four parts:

1) ProgramProgramProgramProgram LoadingLoadingLoadingLoading: putting the program into the milling’s computer memory

2) ProgramProgramProgramProgramVerifyingVerifyingVerifyingVerifying: finding errors in a new program

3) RunningRunningRunningRunning Control:Control:Control:Control: running part of the program to debug it

4.24.24.24.2 ProgramProgramProgramProgram LoadingLoadingLoadingLoadingA program file must be “loaded” into the milling’s memory before it can be “executed” (i.e.,

cut a part or do some other operations automatically). The program file itself is a series of

program lines called blocks that direct the milling through a series of various operations

automatically. The programmer who writes the program file sets these operations.

Only one program at a time can be “loaded” for execution by the milling. Usually many

programs that have been written are stored in the milling’s computer. “Loading” is the

process of picking one of these programs to be executed.

The following steps are to load a program for execution.

1) From the physical Menu keys located just below the LCD screen, press the F1

physical key just below the F1 [[[[PROGPROGPROGPROG]]]] soft key on the LCD screen. Then the soft

keys would change to ProgramProgramProgramProgram FunctionsFunctionsFunctionsFunctions and ProgramProgramProgramProgram SourcesSourcesSourcesSources. These functions

only appear after pressing the F1 PROGPROGPROGPROG key.

3) When pressing the OPENOPENOPENOPEN soft key, the LCD screen shows a file directory: a list of

program files is like the ones below. The left column shows the name of the

program file, the middle column shows the size of the file and the rightmost file

shows the last date the file was changed. NoteNoteNoteNote that program files always start with

the letter “O”. The example below shows 10 different program files, each 1K long

(one kilobyte) and last changed in Dec. 2006.

4.34.34.34.3 ProgramProgramProgramProgram VerifyingVerifyingVerifyingVerifyingA program which has just been created or changed should be verified before it is actually

used to cut parts. Program verifying can find errors in the program without actually running

the machine and possibly damaging the milling or the workpiece.

The following steps are used to verify a program:

1) Load the program to the milling’s computer memory as shown above.

2) To verify, you must be in either AUTO mode (Automatic mode) or SBL

mode (Single Block mode).

3) Press the F5 key corresponding to VERIFYVERIFYVERIFYVERIFY in the ProgramProgramProgramProgram FunctionsFunctionsFunctionsFunctions menu.

functions VERIFYVERIFYVERIFYVERIFY and PAUSEPAUSEPAUSEPAUSE are in bold type. The other functions are in light

type, signifying that they can not be used during the VERIFYVERIFYVERIFYVERIFY process.


5) Press the CycleCycleCycleCycle RunRunRunRun button on the Machine Control Panel (MCP) to start the

VERIFYVERIFYVERIFYVERIFY process.

6) As the program is verified, the lines of the program are displayed. The line being

verified is highlighted in yellow. As the verification progresses, the yellow line

moves line-by-line from the top to the bottom of the program. The LCD screen

will display an error message if an error is found. Otherwise the cursor (yellow

highlighted line) will return to the start of the program.


7) Note that there is no motion of the cutter or any other action that takes place. The

VERIFYVERIFYVERIFYVERIFY process is a simulation of the motion or action that would take place.

8) View different settings of the LCD display using Program Function F9 VIEWVIEWVIEWVIEW.

For complex or large parts, more than one day may be required to finish machining. You

may need to turn off the machine before it’s done. In this case, the milling’s memory should

store the current block location and recover from this location to continue machining later.

Break point functions do this. In order to save the location for restarting the program later,

you need to know three procedures: savingsavingsavingsaving the break point when you stop, loadingloadingloadingloading the

saved break point and recoveringrecoveringrecoveringrecovering from the break.

4.4.64.4.64.4.64.4.6 B.P.B.P.B.P.B.P. SaveSaveSaveSave

The first of the three break point functions is saving the break point when you stop the

information to the typed file.

4.4.74.4.74.4.74.4.7 B.P.B.P.B.P.B.P. LOADLOADLOADLOAD

If you haven’t turned the milling power off after the B.P. SAVE, you can restore the

breakpoint directly with B.P. LOAD. For example, if you just leave for a lunch break, you

can do a B.P. SAVE before you leave and then resume again quickly when you return.

However, if machine has been powered off after a B.P. SAVE operation, you must recover

the break point: first the milling must be homed (i.e., perform the “Reference Point

Approach” procedure) after turning the power on. Since the workpiece will still be in the

chuck, you should be careful on which axis you home first (X, Z and perhaps C) to avoid a

collision between the cutting tool and the workpiece.

The following steps are to load a break point:

1) The break point program has been loaded into memory

2) Press F2 RUNRUNRUNRUN CTRLCTRLCTRLCTRL from the Main Menu to get the Block submenu.
