Some functions described in “FANUC Series 16/18/160/180–MODEL BDescriptions” (B–62442E) are supported by the 16–LB, but may bedifferent in specification from those of the 16–LB. This chapter describesthe differences.

If an emergency stop occurs when the oscillator is operating, the oscillatorshutter is closed, the laser beam is turned off, the high–frequency powersupply is turned off to stop discharge, and the assist gas selection signalsquit selection, all at the same time the machine stops.After the machine is released from the emergency stop state, turning onthe discharge start signal causes the oscillator to operate.

If the feed hold command is issued when the machine is running with thelaser beam turned on, the machine is decelerated to stop, the laser beamis turned off, the shutter is closed, and the assist gas supply is stopped. Pressing the cycle start button starts supplying the assist gas, opens theshutter, turns on the laser beam, and causes the machine to run again.

Even if laser beam output has been programmed, the machine lockfunction causes the laser beam output commands to be ignored and allowsonly the machine move commands to be calculated. As a result, themachine does not move, but the current position display is updated. If thepierce command G24 is executed, it works as a dwell command withoutoutputting a laser beam.

Even if laser beam output has been programmed, the dry run functioncauses the laser beam output commands to be ignored. As a result, themachine dry–runs with the laser beam turned off. If the pierce commandG24 is executed, it works as a dwell command, because a laser beam isnot output.

When a block in which machining is carried out with the laser beamturned on ends, feeding stops, the laser beam is turned off, the shutter isclosed, and the assist gas supply stops. Pressing the cycle start buttonstarts the next block. If this block requests to perform machining with thelaser beam turned on, the assist gas is supplied, the shutter is opened, thelaser beam is turned on, and machining is restarted.

Machining can be restarted at a specified block. After specifying a blockwhere you want to restart by placing the cursor on it in EDIT mode, selectthe memory operation mode and run the program from the beginning, andthe block immediately preceding the specified block is searched for.When that block is found, and its end is located, the search is completed.When the block search is completed, pressing the cycle start buttonrestarts machining at the end of the found block. The laser beam has beenturned off. When the program restarts, the beam is turned on or off asdirected. All M code output signals are output to the PMC during the search. Sothe PMC must respond to them.

B–62592EN/01 6. ASSIST GAS CONTROL

23

Assist gas control is performed using a direct gas pressure controlcommand or a flow pattern command.

(1)Direct gas pressure command

The type and pressure of an assist gas to be used and the settling timeof the assist gas pressure can be controlled directly using the P, T, andR addresses.

G32 with P�0 opens the shutter, and sends out the assist gas selectionsignals and the assist gas pressure analog signal.G32 with P=0 closes the shutter, and turns off the assist gas selectionsignals and the assist gas pressure analog signal.

G32P–(T–R–) ; The parameters enclosed in parentheses are omissible.

P=gas type : Specifies the assist gas type.0 : The shutter is closed, and no assist gas is

selected.1 to 7 : The shutter is opened, and an assist gas

is selected.

T=gas pressure : Specifies the assist gas pressure.The specified gas pressure is output in form of analog voltage.

R=settling time : Specifies the time required before the pressure of assist gas reaches the specified value.

(2)Control using the cutting condition setting function

The type and pressure of an assist gas to be used and the settling timeof the assist gas pressure can be controlled using the registered cuttingcondition data.

G32 with L�0 opens the shutter, and sends out the assist gas selectionsignals and the assist gas pressure analog signal.G32 with L=0 closes the shutter, and turns off the assist gas selectionsignals and the assist gas pressure analog signal.

G32L– ;

L=0 : The shutter is closed, and the assist gas supply is stopped.L=1 : The shutter is opened, and the assist gas supply is started

according to cutting condition data.L=2 : The shutter is opened, and the assist gas supply is started

according to piercing condition data.

This command uses the gas type, pressure, and settling time specifiedas cutting condition data in E code format.(See the description of the cutting condition setting function.)

(3)Flow pattern command

The following pattern of data such as pre–stage pressure and time,cutting pressure, and post–stage pressure and time is previouslyregistered as a flow pattern. It can be specified using the Q address.

7 SHUTTER OPEN/CLOSE CONTROL

The oscillator output section has a safety provision. It is a shuttermechanism that can mechanically shut off the laser beam output asrequired. To output the laser beam, it is necessary to open the shutterpreviously.

There are two methods for opening the shutter automatically, as describedbelow. Which method to use can be selected using parameters.

(1)Command using the G code

In automatic operation mode, specifying G32P–; or G32L–; opens orcloses the shutter.

� If P�0 or L�0, the shutter is opened.

� If P=0 or L=0, the shutter is closed.

(2)Command using the PMC signal

The shutter open signal from the PMC can be used to open or close theshutter. This method may be selected when you want to control theshutter using the M code or from the outside.

� Turning on the shutter open signal opens the shutter.

� Turning off the shutter open signal closes the shutter.

Another safety provision is available. It is a shutter lock signal used todisable the shutter from opening. When the shutter lock signal is on, itnullifies the shutter open command, thereby keeping the shutter closed.

When a laser output command is fetched from the program, if the Saddress has a specified value, it updates the power value in the laser dataarea. The laser data area holds specified values. When a laser outputcommand is executed, data is read from the laser data area and sent to thelaser oscillator.The laser data is also displayed on the laser setting screen, and can beupdated using key entries. There are two types of power value laser dataareas: one type for contouring and the other type for piercing.Power values specified in G01, G02, G03, and G12 are stored in the laserdata area for contouring. A power value specified in G24 is stored in thelaser data area for piercing.The PMC can override the power value during command execution. Theoverride value can range between 0 and 200% (in 1% steps).

Q : Specifies the pulse duty cycle.Valid data range : 0 to 100Minimum increment : 1%

When a laser output command is fetched from the program, if the Qaddress has a specified value, it updates the pulse duty cycle in the laserdata area. The laser data area holds specified values. When a laser outputcommand is executed, data is read from the laser data area and used, inconjunction with the pulse frequency described earlier, to calculate theon/off time of the pulse, which is then sent to the laser oscillator.The laser data is also displayed on the laser setting screen, and can beupdated using key entries. There are two types of pulse frequency laserdata areas: one type for contouring and the other type for piercing.Pulse duty cycle values specified in G01, G02, G03, and G12 are storedin the laser data area for contouring. A pulse duty cycle value specifiedin G24 is stored in the laser data area for piercing.The minimum increment of the pulse duty cycle is 1%, but the resolutionis 0.01 ms. Therefore, the actual minimum increment is rounded up to thisresolution.If the duty cycle is specified as 100%, the output command is placed inthe continuous mode (CW).The PMC can override the pulse duty cycle value during commandexecution. The override value can range between 0 and 150% (in 10%steps).

The laser beam can be radiated for a specified period of time withoutinvolving machine movement. This function is called a piercingcommand. It can be used for the laser beam to pierce the workpiece aspreprocessing for cutting.

G24 S_P_Q_Rxxxxxxxx ;

R : Specifies the piercing timeValid data range : 0 to 9999.999 sMinimum increment : 1ms

G24 is a one–shot command. So, it must be issued every time thecorresponding function is required. Values specified after the S, P, Q andR in G24 cause the corresponding operations. If the S, P, Q, or R isomitted from G24, the corresponding value is supplied from the laser dataarea.

The piercing time specified in G24 can be changed using an externalsignal.

(1)Extending the piercing time

If the “extension” signal is turned on during piercing, piercingcontinues as long as the signal remains on. When it is turned off,piercing ends, and the next block is executed.

Preset time

If the output countis 0, the laser beam is turned off without executing the corresponding data.When another command is issued, execution begins with executionsequence 1 without executing the remaining data. If the output count is–1, it is not used for laser beam on/off control. This control will be basedon whether a cutting feed command is active, instead. (This is used forcutting operation.)

8.2.3Execution SequenceData RegistrationFunction

1 Piercing output command

G24; specifies piercing. Data is read sequentially from a registerspecified by the E code to output a laser beam.The E code can be specified independently.

G24 E_ ;

E=register number (1 to 8)

Data is read sequentially from a specified execution sequence register,starting at sequence 1 to output a laser beam. When output iscompleted for the specified output count, data at sequence 2 is read toperform the same control. Output control ends when the output countis 0, or when data at sequence 3 is executed.

2 Cutting output command

When a cutting command (G01, G02, G03, or G12) with a registernumber specified with the E code is executed, the laser beam is turnedon according to the contents of the register. When the cutting feedcommand ends, the laser beam is turned off. The output count mustbe –1 for cutting operation.

The E code can be specified independently.

Laser processing signal

If the oscillator mirror gets dirty, the laser output drops.When the laser oscillator starts up, a power compensation factor iscalculated automatically and used to compensate the laser output for adrop that occurs due to a dirty mirror. However, compensation has a lowerlimit to a drop in the output. If the output drops so badly that the requiredcompensation exceeds the allowable level, an alarm is indicated on theCRT screen, and the output drop alarm signal is issued.Pressing the reset button clears the alarm indication on the CRT screen,but does not clear the output drop alarm signal.This signal is kept on until the mirror is cleaned to resume the initialoutput level.

A laser alarm is raised if an error related to the laser oscillator is detected.

On receiving an analog signal from the detector, the CNC subtracts thereference deviation E0 from it and multiplies the difference by loop gainK to calculate the speed command for the Z–axis. The loop gain can bespecified using a parameter.

Vz = 60&K (E–E0)

where Vz = Z–axis speed (mm/min)K = tracing loop gain (typically 30 s–1)E = input deviation (mm)E0 = reference deviation (mm)

The normal gap deviation (�E = E–E0) for tracing control is calculatedas follows:

If the fifth and sixth axes are specified as a controlled axis, and attitudecontrol is specified, the nozzle attitude can be controlled around the twoaxes, thus enabling configuring of a three–dimensional machine tool.Either of the following two attitude control types is supported accordingto the axis configuration of the nozzle head section.

1 Attitude control A (zero–offset nozzle)

2 Attitude control B (offset nozzle)

PROCESSING SYSTEM

63

The nozzle tip position fixed type (zero offset type) mechanism isconfigured with the α axis (no.4 axis) to rotate around Z axis, and therotational axis β axis (no.5 axis) recorded in this α axis. It possesses thestructure that the tip of the nozzle is arranged at the point where therotational center line of the α axis crosses the rotational center line of theβ axis.This type has the following characteristics:

1 Movement of the nozzle tip position is performed by X, Y, Z axes, andthe attitude control of the nozzle is performed by α, β axes. Therefore,movement of the position and attitude control can be controlledindependently.

2 Contour precision is good because control is easy.

3 Operability is good.

4 The structure of the nozzle head section is complicated and easilyinterferes with the workpiece.

The offset type mechanism is configured with the α axis (no.4 axis) torotate around Z axis, and the rotational axis β axis (no.5 axis) recorded inthis α axis. It possesses the structure of being arranged such that therotational center line of the α axis is perpendicular to the rotational centerline of the β axis, and that the rotational center line of the α axis does notcross the center line of the nozzle.This type has the following characteristics:

1 When controlling the attitude of the nozzle by α and β axes, it isnecessary to command the moved amount to the X, Y, Z axes, and tocontrol to return to the original tip position of the nozzle, because thetip position of the nozzle moves.

2 Because there is interference between axes, control is complicated andcontour precision is decreased.

3 The structure of the nozzle head section is simplified, and it is easy toavoid interference with the workpiece.

(1)Mode selection

In automatic operation, the nozzle tip fixed mode automaticallyoccurs; in manual operation, nozzle tip fixed mode and independentaxis mode can be switched by DI.

(2) Independent axis mode

This is the mode that the commanded axis performs only the rotationoperation if α axis or β axis is commanded.According to the command, if α axis or β axis rotates, because the tipposition of the nozzle changes, change the coordinate values of therelative coordinate system and workpiece coordinate system by thechanged X, Y, Z coordinate value amounts, and match the nozzle tipposition and the coordinate system.

(3)Nozzle tip fixed mode

This is the mode that the nozzle tip position becomes the rotationalcenter, and the commanded axis performs the rotation operation bymeans of simultaneously moving the linear axes X, Y, Z after rotatingthe commanded axis if α axis or β axis is commanded.According to the command, if α axis or β axis rotates, because the tipposition of the nozzle changes, move each X, Y, Z axis by the changedX, Y, Z coordinate value amounts, and return the nozzle tip positionto its original position.At this time, the relative coordinate system of X, Y, Z axes and theworkpiece coordinate system are not affected, but the machinecoordinate system X, Y, Z axes are affected.

In nozzle attitude control, as shown in the diagram of the axisconfiguration of the nozzle head, the β axis motor is arranged around theZ axis. In the case of a structure which transmits by gear, if the α axis iscommanded, the housing rotates and the nozzle rotates around the Z axis.

However, simultaneously at this time gear B must rotate around gear A.This movement results in the nozzle being rotated by the β axis.Namely, if the α axis rotates by an α axis command, a rotational operationsimultaneously occurs at the β axis.Interaction control is the function to automatically generate commands inthe β axis of the same amount as the α axis commands in order to cancelthe rotational operation of the β axis for a nozzle head of axisconfiguration such that the β axis rotates by the α axis commands. Thecommand polarity can be selected by parameter.

A machining program is subjected to three–dimensional conversion byspecifying a target point in reference to an arbitrary point in the coordinatesystem of the machining program. This function can work in two modes:Mirror image conversion and three–dimensional movement conversion

(1)Mirror image conversion

When the reference point P0 (x, y, z) in the coordinate system of aprogram to be converted and the target point Q0 (i, j, k) in a coordinatesystem after conversion are specified, this function obtains a plane thatis perpendicular to the line connecting the two points and bisects it, asa symmetry plane, then applies mirror image conversion to thatprogram with respect to this symmetry plane.

If there is a movable reflector, the propagation distance between theoscillator and condensing lens varies as the reflector moves.

Generally, stable machining characteristics are obtained within a limitedpropagation distance range. In a large machine tool in which the reflectorhas to move through a long distance because of its mechanical structure,the required propagation distance may exceed its limit, hampering stablemachining over the stroke of reflector movement. To solve this problem,the 16–LB is provided with an optical path adjustment axis and an opticalpath length compensation function. When a command is issued whichrequests that the reflector be moved, the optical path length compensationfunction automatically adjusts the optical path adjustment axis tomaintain a constant optical path length.

Optical path length compensation uses the following mechanism.1 An axis (called the U–axis) must be available along which a beam

reflecting mirror block (shown below) moves linearly to vary thepropagation distance.

2 The U–axis should be configured to change the propagationdistance α times (1 to 511) as much as the movement of the mirrorblock.

3 The maximum speed of the U–axis should be higher than or equalto 1/α the total rapid traverse rate of the axes that can change theoptical path length.

4 All axes including the U–axis should have reference point. Theoptical path length is calculated based on the reference point.

5 An interference protection provision should be installed for all axesthat may otherwise interfere with the U–axis.

Oscillator

U–axis

Nozzle head

(1)Detectors on the controlled axes can be incremental and/or absolutepulse coders (APC). The two types can be intermixed.

(2)Any axis from the fourth axis to the eight axis can be assigned as theU–axis.

(3)A U–axis move command is generated based on the movementdistance of an axis that can change the optical path length. So, it isnecessary to specify controlled axes (except the U–axis) that canchange the optical path length, using parameters.

11.1OPTICAL PATH LENGTHCOMPENSATION


79

(4) If the movement direction of an axis that can change the optical pathlength does not match the polarity of a change in the optical pathlength, the polarity may be inverted for calculation purposes.

(5)A parameter can specify whether to reflect the amount of movementof an axis under tracing control into the U–axis move command.

(6)Optical path length compensation is possible.When all axes (including the U–axis) are at their reference points, theoptical path length is defined as the reference optical path length,which can be subjected to compensation.When optical path length compensation is enabled, the referenceoptical path length can be set up regardless of the position of thereference point.If a parameter specifies a mirror position compensation value, turningon the constant–optical path length control start signal (LRCS) withall axes set at their reference points causes the U–axis to moveautomatically through the specified distance away from its referencepoint and to begin optical path length compensation.For an APC axis, if its reference point has been set up, theconstant–optical path length control start signal is accepted even if theaxis is not at the reference point.

(7)The distance through which the U–axis should move is calculated asfollows:

Burning may occur during laser machining, preventing machining fromcontinuing. In such a case, machining may be resumed by putting themachine back in the state in which it was before burning. This is done bya machining restart function.If a machining error is detected, the machining restart function moves themachine back to a specified position through the same path it had takenbefore the error occurred, while the laser beam is kept turned off. Whenthe machine gets back to the specified position, the machining restartfunction again places the machine in an operable state and causes it tomove forward to the position where it started going back. At this point,the machine restarts machining according to the programmed commands.This function cannot be used together with the three–dimensionalmachining function. This function is based on the retrace function of the16–MB. So, it is necessary to specify the retrace function also. Themachining restart function conforms to the specifications of the retracefunction.The machining restart function behaves as described below.A PMC ladder program can be created to restart machining automatically.

2 When automatic operation starts with the retrace signal selected, thepoint where automatic operation starts is recorded as a retrace startpoint, and the machine retracts in the +Z direction through a specifieddistance.

3 When retracting is completed, the machine retraces the specifieddistance, then stops. After confirming the retrace completed signaland turning off the retrace signal, triggering automatic operationcauses the nozzle to approach the surface of the workpiece.

4 After the nozzle approaches the workpiece surface, the assist gas isturned on.

11.2MACHININGRESTART FUNCTION


81

5 A move command that will end at the retrace start point is generatedautomatically, the laser beam is turned on, and the machine startsmoving forward again. When it reaches the retrace start point, a blockthat was executed at 1 is called to resume programmed operation.

6 After restart, it is checked whether the restart completion distance hasbeen passed through.

7 If no machining error is detected during movement through the restartcompletion distance, machining is continued.

8 If a machining error is detected before the restart completion distanceis passed through, steps 2 to 4 are retried.

9 If retry is repeated a specified number of times, it is assumed thatmachining restart is impossible, and skip operation is carried out.

10 The machine begins positioning at the end of the block executed at step1 . When it gets to the end of the block, it stops there in single blockstop mode.

11 After confirming that the skip completed signal is on and turning offthe retrace signal, triggering automatic operation causes the nozzle toapproach the workpiece.

12 After the nozzle approaches the workpiece surface, the assist gas isturned on, and piercing is carried out under the machining conditionused most recently. When piercing is completed, the cutting assist gasis selected.

13 The laser beam is turned on, and the next block begins execution.
