MACHINE LAYOUT

The LC-α machine and the LC-β machine are ahybrid system, with moving the material in the X-axis and moving the laser head in the Yaxis. The LC-α machine moves the material across a ball-transfer table, while the LC-β machine moves the pallet and material in the Xaxis. The LC-θ or FO machine moves the laser head in the X-axis and Y-axis.

With the axes at the reference positions, the laser head is at the X+ and Y+ corner of the working area for the LC-α, -β, and -θ machines and is at the X+ and Y– corner of the working area for the FO machine.

COORDINATES AND DIMENSIONS

The NC used on these machines accepts information within certain ranges of values. The following table lists allowable values for various uses.

Numeric formats/allowable range of values

Items Metric

X, Y, Z +/– 99999.9999 +/– 9999.9999

G 1 to 9999 1 to 9999

N 0 to 99999 1 to 99999

O 0 to 9999 0 to 9999

R, I, J +/– 99999.9999 +/– 9999.9999

X (as parameter) .001 to 9999.999 .001 to 9999.999

P 1 to 9999 1 to 9999

Inch

G20 Select INCH coordinates

May be used in MDI, or at the beginning of a program on a line by itself. After changing coordinate system, G92 must be re-set. This may be done by re-referencing the machine (using RETRACT mode) or by using the G92 or G130 instruction.

NOTE

O In a program, must be followed by either a G92 statement for INCH

coordinates, or a G130 instruction.

I-7

G21 Select METRIC coordinates

NOTE

O In a program, must be followed by either a G92 statement for METRIC

coordinates, or a G130 instruction.

G90 Absolute programming

When G90 is commanded, all coordinates in the program refer to current program origin or to the absolute origin point.

G90 is MODAL and remains effective until G91 is commanded.

G91 Incremental programming

When G91 is commanded, all coordinates in the program are incremental distances from the previous coordinate.

G91 is MODAL and remains effective until G90 is commanded.

G92 Establishing coordinate system

The G92 command is optional, unless the system has been switched between INCH and METRIC. Once the machine has been powered up and referenced, the standard coordinate system is ready to use.

The G92 instruction may be used to establish an absolute origin point for programming.

The usual (default) absolute origin point for the X and Y axes corresponds to the corner of the sheet of material closest to the junction of the work clamps and the X-gauge block.

NOTE

O The G92 command must be immediately followed by the appropriate X, Y, and

Z values, all on the same block of information.

When the machine has been referenced and is at “home” reference position, the NC’s position display (FUNC+POS keys) displays values which may be used in the G92 statement for the active units system (Inch/MM).

The following charts list dimensions for some common machines. If your machine does not appear here or the numbers do not seem to “match up”, confirm with AMADA the correct values for your machine and write them in below.

FO3015 3070 {120.8661} 1550 {61.0236} 200 {7.8740}

G93 Origin point offset

The G93 command establishes a reference origin point, relative to the absolute origin point, anywhere within the limits set by G92. This is done for ease of programming.

G93 X__ Y__ Z__;

X…X-offset

Y…Y-offset

Z…Z-offset (normally zero)

Example

G93 X0.2 Y12.0 Z0;

Shifts the part-program reference point 0.2 inches in the plus-X direction and 12.0 inches in the plus-Y direction from the absolute origin point or current reference established by a G98 multiple part instruction (see page I-33).

To cancel the origin point offset:

G93 X0 Y0 Z0;

NOTE

O The G93 command must be immediately followed by the appropriate X, Y, and

Z values, all on the same block of information.

O When programming multiple parts using G98, the G93 refers to each part

origin as set by G98.

O If G91 (incremental coordinates) is effective when G93 is commanded, it

becomes an incremental offset from the previous G93. Otherwise it replaces the previous G93.

O When using the cutting database, the system automatically corrects for

material thickness. Unless cutting formed materials or not using the cutting database, use Z0.

G120 Measurement probe (for LC-θ)

Compensates the machine coordinate system and program origin point by using the optional measurement probe. For details, refer to the Operator’s Manual.

I-9

MOTION INSTRUCTIONS

Motion instructions belong to two groups: rapid traverse, and contouring rapid traverse (G00) is strictly for positioning the material to a particular location. Contouring instructions (G01, G02, and G03) are used to move the material through a particular path under the laser head at a particular speed (feedrate).

The system defaults to absolute coordinates programming.

G00 Rapid traverse

This command is for positioning. It moves the table and laser head to the designated X, Y axis location at the current traverse speed. (default is maximum speed)

G00 X__Y__;

The Z-axis may also be positioned, but not on the same block as with X, Y axes.

Only axes included in the command are actually moved.

NOTE

O The laser beam is OFF when G00 is active.

O Each axis moves independently, so the material path is usually not a straight

line.

O G00 forces an in-position check at the commanded end point. This may be

used to force a sharp corner during processing. (Use G00 on separate line.)

O Maximum rapid traverse speed is 40 m/min (1575 ipm). The RATE buttons

on the CNC control panel can reduce travel speed to 50% or 25% of this.

O G00 is MODAL: Once commanded, it stays in effect until a G01, G02, or G03

is commanded.

O Absolute/incremental programming is available by G90/G91.

G01 Straight line motion

Moves the material from current position to commanded location via a straight line. Feedrate, assist gas selection, laser power, pulse rate, etc. are determined by the active material and table selection (M102, En) and by active operator overrides.

G01 X__ Y__;

X…X-coordinate (mm or in.)

Y…Y-axis coordinate (mm or in.)

NOTE

O G01 is MODAL: once commanded, it remains effective until a G00, G02, or

G03 is commanded.

O The machine is capable of moving all three axes at the same time, in this

mode. Absolute/Incremental programming is available by G90/G91.

O A feedrate must be specified for G01, G02, G03. This is normally done by

M102 and Enn, but may also be done using an Fnnnn feedrate command.

O During machine operation, feedrate may be overridden from 0% to 255% in

1% steps from the operator panel.

O The feedrate of the optional subcarriage of the FO machine is set by an NC

parameter.

G90 G00 X11.0 Y20.0;

G91 G01 X7.0 Y4.0;

G02 Circular arc CW

Moves the material from current position to commanded location via a clockwise arc at a commanded radius and feedrate.

G02 X__ Y__ R__ (or I__ J__);

Example of R format

Example of I, J format

O G02 is MODAL: once commanded, it remains effective until a G00, G01, or

G03 is commanded.

O The parameter “R” has priority over “I” and/or “J”, when used on the same

line.

O The radius R (or that computed from I, J) must be non-zero.

O Absolute/incremental programming available by G90/G91 only affects the end

point. The I, J values are always incremental from arc starting point.

O If the angle of the arc is greater than 180 degrees, the R value must be

negative.

O The machine is capable of moving only two axes at the same time, in this

mode.

O To cut a full circle, I and J must be used, rather than R.

O A feedrate must be specified for G01, G02, G03. This is normally done by

M102 and En, but may also be done using an Fnnnn feedrate command.

O During machine operation, feedrate may be overridden from 0% to 255% in

1% steps from the operator panel.

X… X-coordinate (mm or in.)

Y… Y-axis coordinate (mm or in.)

R… Radius of arc (negative value creates an arc > 180°)

(can use either R or I, J in instruction)

I… Distance in the X-direction from the staring point to the arc

center.

J… Distance in the Y-direction from the staring point to the arc

center.

G03 Circular arc CCW

Moves the material from current position to commanded location via a counter-clockwise arc.

This command is used to cut material in a counter-clockwise arc at a commanded feedrate and radius. The X and Y values specified determine the endpoint of the cut. The R value specified determines the radius of the cut.

G03 X__ Y__ R__ (or I__ J__);

X… X-coordinate (mm or in.)

Y… Y-axis coordinate (mm or in.)

R… Radius of arc (negative value creates an arc > 180°)

I… Distance in the X-direction from the starting point to the arc

J… Distance in the Y-direction from the starting point to the arc

NOTE

O G03 is MODAL: once commanded, it remains effective until a G00, G01, or

G02 is commanded.

O The parameter “R” has priority over “I” and/or “J”, when used on the same

line.

O The radius R (or that computed from I, J) must be non-zero.

O Absolute/incremental programming available by G90/G91 only affects the end

point. The I, j values are always incremental from arc starting point.

O If the angle of the arc is greater than 180 degrees, the R value must be

negative.

O The machine is capable of moving only two axes at the same time, in this

mode.

O To cut a full circle, I and J must be used, rather than R.

O A feedrate must be specified for G01, G02, G03. This is normally done by

M102 and En, but may also be done using an Fnnnn feedrate command.

O During machine operation, feedrate may be overridden from 0% to 255% in

1% steps from the operator panel.

G09 Exact stop

A command effective for a specified block only. Axis travel is decelerated at the ending point of the block and checked for in-position. The next block is then executed.

G09 (G01 X__ Y__);

The command in parentheses may be G02 or G03.

NOTE

O The in-position check refers to the check made to see if the axis travel has

reached the specified position (within the range set by a parameter).

G61 Exact stop check mode

This command requires the machine to stop and wait for verification of each programmed position before moving toward the next programmed position.

NOTE

O G61 must be canceled before cutting any blended radii or using any of the

standard hole commands (G111 to 115) either singly or in patterns.

O Once G61 is commanded, it will stay in effect until a G64 is commanded.

G64 Contour cutting mode

This is the default cutting mode for the machine. No position verification is required prior to movement towards the next programmed position. This mode is in effect until changed by a G61 command.

I-16

G160 Space arc interpolation (for LC-θ)

G160 Xx1 Yy1 Zz1 Va1 Ub1;

Xx2 Yy2 Zz2 Va2 Ub2;

The first block indicates the center point of the arc, and the second block indicates the ending point of the arc.

G160 is MODAL and remains effective until G00, G01, G02 or G03 is commanded.

When the center point and ending point are commanded, the arc to the ending point is obtained.

When the commands for the V- and U-axes are omitted, the nozzle moves in that attitude. When the ending point is not commanded and another code (e.g., G01) is commanded, the conditions for the arc are not met. In this case, the nozzle moves with the path from the starting point to the center point straightly interpolated.

When the center point is omitted, the attitude of the nozzle is automatically controlled according to the radius of the arc from the starting point to the ending point. When another space arc interpolation is commanded, the ending point becomes the starting point of the next arc.

GENERAL

O Program numbers

Each program must be assigned a program number. This number is used to separate the 200 different programs that can be stored in memory at one time. The program number must begin with the letter “O”.

O Any number from 0 to 8999 can be used.

O Program 0 (zero) should be left vacant, as it can easily be overwritten during

certain extended edit procedures.

O Programs numbered 8000 to 8999 can be protected by setting a parameter.

F Feedrate code

Cutting feedrates are normally specified by using M102 to select material type and thickness, and using E1-E9 to fine-tune or select for type of contour or detail. The F-code may be used to override a standard feedrate, or for material for which an entry does not exist in the database.

NOTE

O In Inch mode, the feedrate is in inches per minute.

O In Metric mode, the feedrate is in millimeters per minute.

O An F code is required only when the M102 functions are not used.

D Offset code

These codes are not used on the LC-α, β machine. Instead, laser beam offset amounts are kept in the cutting parameter database. See the section on laser beam compensation, beginning page I-22, and the section on standard holes, in Part II.

N Sequence numbers

Instruction blocks in a program may be marked or labeled using sequence numbers. When used, a sequence number must be the first address in the program block. The valid numeric range is from 1 to

99999. They do not need to be in numeric sequence.

(Comments)

G04 Dwell

If the block skip button is illuminated, any block of information with this symbol at its beginning will be ignored.

Comments may be placed in a program by enclosing them in parentheses.

If a comment is placed on the first line after the program number, it will be displayed in the program directory listing of the CNC (machine control). Comments should not be mixed into the middle of program lines. Place each comment at the end of a program line or on a separate line.

O1234 (SAMPLE COMMENT);

(THIS COMMENT IS ON A LINE BY ITSELF);

If programming off-line, make sure to use all capitals for comments and instructions.

The dwell function stops the machine for a specified period of time, in seconds.

G04 Xnnnn;

Where .001<=nnnn<=9999.999

NOTE

O CAUTION: Use of G04 between contouring motion instructions (G01, G02,

G03) cancels laser beam compensation.

O When the time period is over, machine operation continues. Use extreme

caution when using the dwell function.

O The minimum dwell value is 0.001 second. This is equivalent to G04 with no

“X” value.
