1. For Safe Operation 1-1 Safety Precautions

1 – 1


The high power laser beam can cause injury to the eye or burns if it is irradiated on the human body. The safety precautions that must be observed when using the laser processing machine are described in this section. Always observe these and use the laser processing machine safely.

1-1-1 Safety countermeasures for laser beam

Special care is necessary as the CO2 laser beam is an invisible far red infrared radiation having a 10.6μm wavelength. If the direct or reflective laser beam should contact the eyes or skin, damage to vision or burns could result, so never radiate the beam on the human body.

(1) Beam passage ducts should be closed during operation.

Do not open any section of the beam passage (beam duct, bend mirror, etc.), when radiating the laser beam.

(2) Use of protective goggles The operator must wear protective goggles or an acrylic protector that covers the face. (This is also applicable for the operator who adjusts the CO2 laser.) Note that the laser beam (CO2) cannot be completely shielded even when wearing protective goggles or a protector. This also applies to the visible beam (red).

(3) The beam shutter must be closed during inspections. Before disassembling or inspecting the processing head and the bend mirror holder (removal, installation, etc., of nozzle, processing lens and bend mirror), stop the oscillation. Also, be sure to close the beam shutter that is provided at the outlet of the CO2 laser.

(4) Provision of warning sign When the CO2 laser beam and visible laser beam are synchronized for operation, the open beam passage (transmission in the open air) is used for the rated output. An enclosure must be provided to prevent persons from entering the beam passage. Additionally, a warning sign "OFF LIMITS DUE TO ADJUSTMENT" should be provided.

(5) Prevention of direct entry of laser beam into eye As the 10.6µm wave length CO2 laser beam is not visible, the visible laser beam (power : approx. 1mW) is used to adjust the beam axis. However, the visible laser beam must not enter the eye because it also will cause damage to vision.

(6) Avoidance of flammable objects As the 10.6µm wave length laser beam is easily absorbed by paper, wood, cloth, etc., these materials will catch on fire if exposed to the beam. Do not place paper, wood, cloth, etc., on the work table.

(7) Prevention of secondary reflection Take special care to secondary reflection from metal surfaces. Especially take care when cutting copper or aluminum workpieces.

(8) Proper removal of workpiece chips If cutting chips or dust accumulate on the conveyor, exhaust duct or dust collector installed below the work table, the spatter and the beam could come in contact and start a fire. Thus, always remove these periodically and clean completely.

1-1-2 Safety countermeasures for laser medium gas and decomposition gases generated during laser processing

In addition to N2, He and CO2 gas, there is CO gas in the laser medium gases. Take care not to inhale these gases. As various plastic materials include fillers and flame retarders, poisonous gases such as NOX, SOX, COX, etc., may be produced as thermally dissolved materials. These gases must be exhausted from the room.

(1) The CO2 laser exhaust gas contains CO gas. Thus, always pipe the vacuum exhaust pipe to an

outdoor site, and make sure that the gas is not directly inhaled.

(2) Installation of protective housing When materials that product flammable gases (CH, etc.) are processed, the machine must be enclosed with a protective housing, and the gases must be exhausted from the housing.

(3) Confirmation of exhaust fan Make sure that the exhaust fan in the protective housing is running during processing.

(4) Confirmation of complete exhausting After completing processing, make sure that the smoke is completely exhausted before entering the protective housing.

(5) Purging is done with N2 during maintenance, so make sure that the air can be exhausted (ventilated) from the room.

1-1-3 Other safety countermeasures

(1) Appoint a manager for the CO2 laser machine to control the keys of the operation panel, etc. The manager must observe all precautions regarding the laser processing machine system to

ensure all workers' safety.

(2) Provide a controlled area around the machine with an enclosure, and prevent unauthorized persons from entering the area.

(3) Do not place flammable materials, explosive chemicals or gas cylinder around the laser processing system.

(4) If the operator might leave the work site during processing, automatic emergency stop system that detects earthquakes and other abnormalities should be installed.

(5) Precautions for cutting aluminum material If both aluminum and iron are cut with laser processing, cutting chips from both will form and accumulate in the work table and dust collecting duct. When cutting both materials with the same processing machine, a mixture of iron oxide and aluminum dust will be created. If a spark comes into contact with this, a thermit reaction will occur generating an intense amount of heat. To prevent this thermit reaction, observe the following conditions and execute maintenance. 1) Periodically remove the chips and dust on the work table and in the dust collecting duct. 2) Clean especially well when cutting both aluminum and iron. 3) These same precautions apply when cutting flammable materials (wood, acrylic, etc.). The

thermit reaction will occur the most easily of flammable materials are mixed in with the aluminum and iron cutting chips.

(6) Precautions for the assist gas regulator The withstanding pressure of the assist gas regulator differs according to the gas cylinder and liquid cylinder. (The primary pressure of the gas cylinder is high at 150kgf/cm2 ∗) and the primary pressure of the liquid cylinder is approx. 30kgf/cm2 ∗).) When used in the combination, the regulator could be damaged, so take plenty of caution to avoid incorrect usage. Have the regulator periodically inspected by a manufacturer specializing in gas handling. ∗ ) : 1kgf = 98066.1358Pa


1 – 3

(7) Do not place hands near the processing head or over the workpiece on the table while the CO2 laser processing machine is operating. Doing so could lead to injuries from the laser beam, or catching if the table moves while a hand is extended over the workpiece.

(8) When cutting a long narrow workpiece in the Y axis direction, the workpiece could drop after cutting and become caught between the chuter and chip conveyor. To prevent this, use the work support pins and install a workpiece drop preventing ledge in the X axis direction. The processing program for the workpiece drop preventing ledge is included in the floppy disk, so create the workpiece drop preventing ledge as necessary, and use the program.

(9) Install a partition or protective housing in case of burning during processing. Note that burning will easily occur during piercing of thick plates.

(10) Make sure that none of the piping of the piping or wiring is damaged or contaminated.

(11) Always clean and adjust the devices before resuming operation after stopping operation for a long time.

(12) About the “#221 M-POS” parameter in the PROCESSING PARAMETER screen

(1) Function

This parameter is a parameter for restricting the position of beam irradiation. The maximum of the Z-axis height in which beam-on is possible is set up with machine coordinates. When it is going to carry out beam-on above this setting parameter during automatic operation, it becomes alarm (F00024 C: BEAM ON AT HIGH POS.), and beam irradiation cannot be carried out.

(2) How to Use

This parameter is used in order to prevent a beam glaring carelessly during automatic operation. When beam-on needs to be carried out by maintenance etc. in the high position of the Z-axis, please use this parameter value, changing each time. If the work of a maintenance etc. finishes, it will be used returning this parameter to a suitable value. The standard is taken as the value on +70.000mm (Z-axis machine value) from the minus software limit value of Z- axis. Although restriction starts with this parameter, please put neither a hand nor the body near a processing head and into a processing table by any means during processing.

9-4 START POINT RETURN key 9-4-1 Explanation of key

By using the key, the positioning operation can

be simplified for when repeatedly processing from the same position. This key can be used by pressing it simultaneously

with the key when the axis movement is stopped in a state other than automatic operation start

in a mode other than the handle mode. (Such as in after CNC resetting or when automatic operation is halted.) The key lamp flickers while moving to the processing start point, and turns OFF when the movement is completed. If the key is pressed again while flickering, the movement will be canceled and the lamp will turn OFF.

9-4-2 Registering the start point

The start point is registered automatically when in the automatic operation mode. The point is registered when the START switch is pressed while not in automatic operation. That position (X, Y

and Z axes machine coordinates) is registered. As the old start point data is overwritten, the latest start point position will be valid. This start point data is held even when the power is turned OFF, so if zero point return is carried out after turning the power ON at the next operation, positioning can be carried out to the previous start point with this function.

9-4-3 Return operations

The return operation is divided into the following two types according to the current position when the

key and key are pressed simultaneously.

(1) When the current X and Y positions differ from the start point:

When the key and key are

pressed simultaneously, first the Z axis will move to the machine coordinate zero point as shown with 1a in the drawing. (#1 will not appear at the [POSITION] area. Then, the X and Y axes will move to the start point as shown with 1b. The movement will take place with rapid traverse.

(2) When the current X and Y positions are the same as the start point (When the operation in (1) above is completed)

When the and key are

pressed simultaneously, the Z axis will move to the start point as shown with 2 in the drawing. The movement will take place with rapid traverse. If the height control is turned ON at the head of the program, press the key once and carry out the operation in (1) above to return just the X and Y axes. Return to start point is carried out with rapid traverse, so when using the HD Series, press the key again, and execute the operation explained in (2) to position the Z axis at a height speed than height control. Note that if the workpiece plate thickness has been changed, etc., make sure that the Z axis will not collide with the workpiece when moving to the start point. (Note) Even if the key is pressed at the start point position, the Z axis will move to the zero

point once with the operation in (1) above.

9-5 FEED HOLD POINT RETURN key 9-5-1 Explanation of key

By using the key, the positioning operation can

be simplified when restarting processing after escaping the processing head when a feed hold state is entered because of an alarm, etc.

This key can be used by pressing it simultaneously with the key when the axis movement is

stopped in a state other than automatic operation start in a mode other than the handle mode. (Such as in after CNC resetting or when automatic operation is halted.) The key lamp flickers while moving to the processing restart point, and turns OFF when the movement is completed. If the key is pressed again while flickering, the movement will be canceled and the lamp will turn OFF.

9-5-2 Registering the restart point

During automatic operation, the restart point is registered when a feed hold state is entered. That position (X, Y and Z axes machine coordinates) is registered. As the old restart point data is overwritten, the latest restart point position will be valid.

9-5-3 Restart operation

The return operation is divided into the following two types according to the current position when the

key and key are pressed simultaneously.

(1) When the current X and Y positions differ

from the restart point:

When the key and key are

pressed simultaneously, first the Z axis will move to the machine coordinate zero point as shown with 1a in the drawing. (#1 will not appear at the [POSITION] area.) Then, the X and Y axes will move to the restart point as shown with 1b. The movement will take place with rapid traverse.

(2) When the current X and Y positions are the same as the restart point (When the operation in (1) above is completed)

When the and key are pressed simultaneously, first the Z axis will move to the

restart point as shown with 2 in the drawing. The movement will take place with rapid traverse. If the height control is turned ON in the program, press the key once and carry out the operation in (1) above to return just the X and Y axes. However, for the HD Series, as the axes return to the restart point with rapid traverse, the key can be pressed again to execute the operation in (2) above to position the Z axis at a higher speed than height control. Note that precautions must be taken to prevent the Z axis from colliding with the workpiece even when moving to the restart point. (Note) Even if the key is pressed at the restart point position, the Z axis will move to the zero

point once with the operation in (1) above.

9-6 2ND and 3RD ZERO PT. RETURN keys 9-6-1 Explanation of keys

By using the and keys, returning to the

2nd and 3rd zero point positions (loading/unloading positions, processing start position, adjustment position, etc.) can be carried out easily.

This key can be used by pressing it simultaneously with the key when the axis movement is

stopped in a state other than automatic operation start in a mode other than the handle mode. Return operation is carried out, and the zero point position can be changed in the handle mode. The key lamp flickers while moving to the 2nd and 3rd zero points, and turns OFF when the movement is completed. If the key is pressed again while flickering, the movement will be canceled and the lamp will turn OFF.

When changing the zero point position, the lamp flickers while the or key is pressed in

the handle mode. If the selection key for the axis name to be changed is pressed in this state, the lamp will change to a stable light, and will turn OFF when the key is released. If 2nd or 3rd zero point return is interrupted during automatic operation (when automatic operation is halted, etc.), the program movement path will deviate in the same manner as the normal zero point return. Thus, do not use this during automatic operation.

9-6-2 Changing the zero point position

The 2nd and 3rd zero point positions can be changed by setting the machine coordinate value directly on the AXIS PARAMETER screen (refer to the "Screen Operation Manual" for details) or by using the handle mode. With the latter method, the handle mode is selected, and the machine is moved to the position to be changed. Then, the axis key for which the coordinates are to be changed is pressed

while holding down the (or ) key.

[Procedure for changing XY coordinate value for 2nd zero point return] (1) Using rapid traverse, etc., move to near the position to be changed. (2) Select the handle mode, finely adjust the position of the axis to be changed.

(3) While holding down the key, press the X and Y axis selection key for approx. 2 seconds.

9-6-3 Return operations With the 2nd zero point (3rd zero point) return operation, the axis will move from the current position

where the (or ) key was pressed to the position registered on the AXIS PARAMETER

screen. The movement will pass through the Z axis machine coordinate zero point. The movement will take place with rapid traverse.

Operation order

When the (or ) key and

key are pressed simultaneously, first the Z axis will move to the machine coordinate zero point as shown with 1a in the drawing. (#1 does not appear at the [POSITION] area.) Then, the X and Y axes will simultaneously move to the 2nd zero point (3rd zero point) as shown with 1b. Finally, the Z axis will move to the 2nd zero point (3rd zero point) as shown with 1c to complete the series of operation.

In particular with the ( )

operation, the Z axis movement to the target position

is contained in the series of operations, unlike the key or key. To avoid unintentional

interference with the workpiece, etc., set the Z axis machine zero point and carry out the final positioning with height control unless repeating this operation often.

9-6-4 Canceling the return

In the following cases, the return operation to the 2nd zero point (or 3rd zero point) will be canceled.

(1) When the key is pressed again during the 2nd zero point return. (When the key is

pressed again during the 3rd zero point return.) (2) When the operation mode is changed. (3) When a CNC alarm occurs. (4) When CNC RESET is pressed. (5) When the servo OFF state is entered with an emergency stop, etc.

10. Height Control

10 – 1

10. Height Control

The height control controls the height with the signals from the height sensor unit (sensor) installed on the end of the processing nozzle. The height of the nozzle from the workpiece obtained with height control can be changed with the nozzle height data value in the execution processing conditions buffer. For details on setting the approach point and retract amount refer to the "Screen Instruction Manual" or "Programming Manual".

(1) The max. speed during height control will differ according to the height sensing unit (contact type,

non-contact type (electrostatic type), air lifting type, etc.). The speed is limited by the rapid traverse rate so the axes will not move at a speed higher than the Z axis rapid traverse rate.

(2) The tracing range during height control is from the soft limit on the Z axis' minus side to the approach point.

(3) The nozzle height from the workpiece in the program can be changed with the processing condition data. The M101 to M110 code data is used in the processing program.

(Note 1) While tracing with height control, do not issue a movement command in the Z axis direction with manual operation (jog mode, rapid traverse mode, zero point return mode, handle mode). If executed, the compensation amount with tracing will be added to the movement command, and the current value counter will be updated. However, the machine stop position will return to the trace position before the movement command.

Even during automatic operation (memory mode), the program coordinates will be updated to the coordinate values following the Z axis command in the same manner as the manual operation. However, the amount compensated with height control will change by that value, and the stop position will return to the trace position before the movement command.

(Note 2) When using the non-contact type height sensor unit, retract the Z axis to the zero point with the rapid traverse if the "Height Control Tracing Fault" or "Nozzle Touch" alarm occurs.

Read the Precautions for Use (given in the separate "Instruction Manual") before using the non-contact type height sensor unit.

(1) Height CONTROL ON

Height control will start when the key is pressed.

With the height control, the axis will move to the set approach point at the rapid traverse (G00) rate, and will stop when the nozzle height between the nozzle and workpiece reaches the set value with the trace function. The approach point can be set on the SENSOR CONTROL PARAMETER screen. The approach point value is set as an absolute value from the Z axis machine zero point. If the key is pressed during height hold, the height hold will be canceled.

(2) Height CONTROL OFF

When the key is pressed during height control (when the lamp is lit), the tracing will end,

and the axis will rise at the rapid traverse (G00) rate by the retraction amount. The retraction amount is set in the same manner as the approach point on the SENSOR CONTROL PARAMETER screen. The retract amount is set as the movement amount from the traced position with an incremental value. The data is held even when the control power is turned OFF. The retract process will not be executed even if the height control is turned OFF during height hold.

② Set the required items on the MULTIPLE SET screen.

Step 1) Display the MULTIPLE SET screen.

Step 2) Set "#1 SEET SIZE S". Set the X and Y dimensions of the base sheet onto which the parts are to be laid out.

When the sheet size is set, and then "#2 PART SIZE P" and "#3 WEB SIZE G" are set, the max. No. of parts that can be laid out on the sheet will be automatically set in "#4 GRID SIZE N". (Note) If "#4 GRID SIZE N" is directly set, the multiple setup will not be affected even

if "#1 SEET SIZE S" is not set.

Step 3) Set "#2 PART SIZE P" and "#3 WEB SIZE G". Set the max. width (max. width when viewing the parts as rectangles) of the X and Y

directions of the parts to be laid out in "#2 PART SIZE P". Set the gap (gap when viewing the parts as rectangles) of the X and Y directions of the parts to be laid out in "#3 WEB SIZE G".

The "PART SIZE + WEB SIZE" will be the pitch for multiple setup.

Step 4) Set "#4 GRID SIZE N". Set the No. of parts laid out in the X and Y directions in "#4 GRID SIZE N". If "#1

SEET SIZE S", "#2 PART SIZE P" or "#3 WEB SIZE G" is set, the "P/(P+G)" calculation results will be automatically set as the max. No. of parts that can be laid out.

If the actual No. of laid out parts differs from the calculation results because the processing start position is not the edge of the base sheet, etc., reset the No. of parts that can be laid out.

Step 5) Set "#5 SKIPPED PARTS NJ". When starting processing from the middle of the layout, set how many parts to skip.

For example, if "5" is set "#5 SKIPPED PARTS NJ", processing will start from the 6th part.

If "0" is set, processing will start from the beginning. This setting is automatically incremented by one when a part is processed during

multiple setup, and functions as the "counter" which indicates which part is being processed currently. "5" is displayed when processing the 5th part.

Thus, if the multiple setup is canceled for any reason, and processing is to be resumed, how far the processing has proceeded is displayed, so the No. of parts to be skipped does not need to be set.

Step 6) Set "#6 ENDING PART NO.NE" When stopping the processing in the middle of the layout, set how many parts to

process before stopping. If "0" is set, processing will take place to the end (all laid out parts set in "#4 GRID

SIZE N".

Step 7) Set "#7 PART PROG. NO.". Set the program No. for the laid out parts. For this setting, set the part program changed to the subprogram in item ①.

Step 8) Confirm "#8 MAIN PROG. NO.". This setting does not affect the multiple setup function, but is set as a memo of the

multiple setup main program No. to be searched and executed. The standard multiple setup main program is 9990. (Note) If the multiple setup file is designated with "21-11 Processing Administration

Function" described in this manual, the program searched in "#8 MAIN PROG. NO." will be searched for. Thus, when using the processing administration, always set the main program No.


21 – 8

Step 9) Set "#9 MOVEMENT TYPE" and "#10 DIRECTION". Set the processing path type for multiple setup in "#9 MOVEMENT TYPE", and set

multiple setup processing direction for the X and Y axes in "#10 DIRECTION". Set "0" for the plus direction, and "1" for the minus direction. Refer to the separate "Screen Instruction Manual" when setting "#9 MOVEMENT

TYPE" and "#10 DIRECTION".

When the submenu key is pressed, the multiple setup type can be set easily

by inputting the type selected from the screen into "TYPE NO" displayed at the lower right of the screen and pressing the key.
