FANUC Series 16/18/160/180 CNCs utilize the latest microprocessor
technology and advanced servo technology. They have an open system
interface that enables the machine tool builders to differentiate their
products.
With FANUC’s proprietary servo spindle control technology and
state–of–the art processor for high–speed computation, the CNCs can
implement high–speed, high–precision, high–efficiency machining. A
personal computer function compatible with the IBM PC* can be
incorporated into your CNC to differentiate or expand it. Other features
of the CNCs include a flat TFT color display for the machine operator’s
panel, a high–speed PMC that can be programmed in the C language,
user–friendly interactive programming, and unmanned factory
automation functions.

The two basic axes are always set to X and Z. Additional axes can be
selected from A, B, C, U, V, W, and Y freely. For the 16-TB (2–path
control), the two basic axes are always set to X and Z on each path, and
additional axes can be selected freely from A, B, C, U, V, W, and Y.

Notes

If U, V , or W is used as an axis name, the G code system
must be either B or C.

M series :

The three basic axes are set to X, Y, and Z. Additional axes can be
selected from A, B, C, U, V, and W freely.
For two–path control, X, Y, and Z are always used as the names of the
three basic axes. Additional axes can be assigned any of A, B, C, U,
V, and W as their names.

(G12.1)

The function in which contour control is done in converting the command
programmed in a cartesian coordinate system to the movement of a linear
axis (movement of a tool) and the movement of a rotary axis (rotation of
a workpiece) is the polar coordinate interpolation. It is an effective
function when a straight line groove is cut on the outer diameter of a
workpiece or when a cam shaft is ground.
Whether the polar coordinate interpolation is done or not is commanded
by a G code.
These G codes shall be commanded in a single block.

G12.1; Polar coordinate interpolation mode

(Polar coordinate interpolation shall be done.)

G13.1; Polar coordinate interpolation cancel mode

(Polar coordinate interpolation is not done.)

The axes (linear axis and rotary axis) on which polar coordinate
interpolation is done are set beforehand by parameters.
Change the mode to polar coordinate interpolation mode by commanding
G12.1, and a plane (hereinafter referred to as polar coordinate
interpolation plane) is selected in which linear axis is made to the first
axis of the plane, and virtual axis being a right angle with the linear axis
is made to the second axis of the plane. Polar coordinate interpolation is
carried out on this plane.
In the polar coordinate interpolation made, the command of linear
interpolation (G01) and circular interpolation (G02, G03) is possible.
And both absolute command (G90) and incremental command (G91) are
possible.
For the program command it is possible to apply cutter compensation.
For the path after cutter compensation is done, polar coordinate
interpolation can be made.
As for feedrate, specify the tangential speed (relative speed between the
workpiece and the tool) on the polar coordinate interpolation plane
(cartesian coordinate system) with F.

Examples

Either of two types of machining can be selected, depending on the

 For those portions where the accuracy of the figure is critical, such as

at corners, machining is performed exactly as specified by the program
command.

 For those portions having a large radius of curvature where a smooth

figure must becreated, points along the machining path are
interpolated with a smooth curve, calculated from the polygonal lines
specified with the program command (smooth interpolation).

In smooth interpolation mode, the CNC automatically determines,
according to the program command, whether an accurate figure is
required, such as at corners, or a smooth figure is required where the
radius of curvature is large. If a block specifies a travel distance or
direction which differs greatly from that in the preceding block, smooth
interpolation is not performed for that block. Linear interpolation is
performed exactly as specified by the program command. Programming
is thus very simple.

When one of the circular interpolation axes is set to a hypothetical axis,

To form a single thread, threading is generally performed several times
from rough machining to finish machining along the same path.
Threading starts when the one-revolution signal from the position coder
attached to the spindle is detected. So threading always starts at the same
point on the circumference of the workpiece, and threading is performed
along the same path on the workpiece. In this case, however, the shaft
must rotate at a constant speed during operations from rough machining
to finish machining. If the spindle speed changes, an accurate thread may
not be produced.

Inverse time feed mode is commanded by G93, and inverse time by F
code. Inverse time is commanded with the following value in a 1/min
unit.

In linear interpolation F= Speed/distance
In circular interpolation F= Speed/radius

When F0 is commanded, alarm occurs.

When a 1-digit number from 1 to 9 is commanded after the F, the preset
speed corresponding the 1-digit number commanded is set as feed rate.
When F0 is commanded, rapid traverse is set.
Set the F1-digit feed rate change input signal on from the machine side,

As shown above in the quadratic curve, it is possible to accelerate and

When the acceleration and deceleration section are connected, the

acceleration/deceleration is called bell–shaped acceleration/deceleration.
Considering a time constant as T c (time spent to accelerate from feedrate
0 up to commanded feedrate F or time spent to decelerate from
commanded feedrate F down to feedrate 0), feedrate accelerates up to 1/2
of the commanded feedrate (F/2) for 1/2 of the time constant (T c/2). The

return

Positioning to the reference position can be done by manual operation.
With jogging mode (JOG), manual reference position return (ZRN)
signals, and signal for selecting manual reference position return axis (±J1
to ±J8) on, the tool the machine is turned on, it decelerates, and when it
is turned off again, it stops at the first grid point, and reference position
return end signal is output. This point is the reference position.
By performing manual reference position return, the machine coordinate
system and the work coordinate system is established.
There is only one method available to perform manual reference point
return:
In the grid method, a certain grid of the position detection is appointed as
the reference position. The reference position position can be shifted by
the grid shift function.

This function moves the machine to around the reference position set for
each axis in the manual continuous feed mode. Then it sets the reference
position for the machine in the manual reference position return mode
without the deceleration signal for reference position return. With this
function, the machine reference position can be set at a given position
without the deceleration signal for reference position return.

1 Place the machine in the manual continuous feed mode, and perform

positioning to a position near but not exceeding the reference position
from reference position return direction (setting by parameter).

2 Enter the manual reference position return mode, then input the feed

axis direction select signal (+) or (–) for the axis.

3 Positioning is made at the grid point located nearest from the current

point to reference position return direction. This point is recorded as
the reference position. If the absolute-position detector is provided,
the set reference position is retained after the power is turned off. In
this case, when the power is turned on again, there is no need for setting
the reference position again.

1 After the reference position is set, when the feed axis select signal (+)

or (–) is input for the axis in the reference position return mode,
reference position return operation is performed in rapid traverse
regardless of which signal (+) or (–) is input.

FLOATING REFERENCE POSITION RETURN (G30.1)

It is possible to return the tool to the floating reference position by
commanding the G30.1.
The floating reference position is located on the machine and can be a
reference position of some sort of machine operation. It is not always a
fixed position but may vary in some cases. The floating reference
position can be set using the soft keys of MDI and can be memorized even
if the power is turned off.
Generally, the position where the tools can be replaced on machining
center, milling machine is a set position on top of the machinery. The
tools cannot be replaced at any machine angle. Normally the tool
replacement position is at any of the No. 1 to No. 4 reference position.
The tool can be restored to these positions easily by G30 command.
However, depending on the machine, the tools can be replaced at any
position as long as it does not contact the work piece.
In lathes, the tool can generally be changed at any position unless it
touches the workpiece or tailstock.
For machinery such as these, in order to reduce the cycle time, it is
advantageous to replace tools at a position as close as possible to the work.
For this purpose, tool replacement position must be changed for each
work shape and this feature can be easily realized by this function.
Namely , the tool replacement position which is suitable for works can be
memorized as the floating reference position and it is possible to return
the tool to the tool replacement position easily by commanding the

position setting that arise when the procedure is performed by different
operators, and to minimize the amount of work involved in making fine
adjustments after reference position setting.
Select the axis for which the reference position is to be set, then perform
cycle start. The following operations are performed automatically:

1. The torque (force) of the selected axis is reduced so that the butting
feedrate is constant. The tool is butted against the mechanical stopper.
Then, the tool is drawn back a parameter–set amount from the
mechanical stopper.

2. Again, the torque (force) of the selected axis is reduced, then the tool
is butted against the mechanical stopper. Then, the tool is drawn back
a parameter–set amount from the mechanical stopper.

When a new workpiece coordinate system is created by specifying G92,
it is determined so that a given point on the tool has a given coordinate
value. So, there is no need to be concerned with old workpiece coordinate
systems. Particularly when the start point for machining is determined
based on the workpiece, the G92 command is useful. In this case, a desired
coordinate system can newly be created even if an old workpiece
coordinate system is invalid.

A workpiece coordinate system can be shifted by using the following
command:
When this command is specified, a new coordinate system is created so
that the current coordinate value (x, z) at a given point on the tool (for
example, the tool tip) becomes (x+u, z+w).
For the x and u values, diameters must be set if diameter programming

WORKPIECE
COORDINATE
SYSTEM PRESET
(G92.1)

The workpiece coordinate system with its zero position away by the
workpiece zero offset amount from the machine coordinate system zero
position is set by returning the tool to the reference point by a manual
operation. Also, when the absolute position detector is provided, the
workpiece coordinate system is automatically set by reading the machine
coordinate value from the detector when power on without performing
manual reference point return operation. The set workpiece coordinate
may shift by any of the following commands or operation:

 When manual interruption is performed with the manual absolute

signal off

 When the travel command is performed by the machine lock
 When axis travel is performed by the handle interrupt or auto/manual

simultaneous operation

 When operation is performed by mirror image
 When the setting of local coordinate system is performed by the G52

or change of workpiece coordinate system is performed by the G82

The workpiece coordinate system shifted by the above operation can be
preset by the G code instruction or MDI operation the same as
conventional manual reference point return.

PLANE SELECTION (G17, G18, G19)

Explanations

 Example 1

 Example 2

A plane subject to circular interpolation, cutter compensation, coordinate
system rotation, or drilling can be selected by specifying a G code.

G18 Zp–Xp plane
G19 Yp–Zp plane

axis parallel

axis parallel

One of the existing parallel axes is determined by an axis address that
appears in the block for which G17, G18, or G19 is specified.

When X and U, Y and V, and Z and W are parallel to each other,
respectively

G17 X_ Y_ XY plane. . . .

G17 U_ Y_ UY plane. . . .

G18 X_ W_ WX plane. . . .

G18 U_ W_ WU plane. . . .

Planes remain unchanged in blocks for which G17, G18, or G19 is not
specified.

 Example 3

G18 X_ Z_ ZX plane. . . .

X_ Y_ Plane not changed (ZX plane). . . . .

If G17, G18, or G19 is specified for a block, and no axis address is
specified in that block, the axis addresses for the basic three axes are
assumed to be omitted.

G17 XY plane. . . . . . . . . . .

G17 X_ XY plane. . . . . . . . .

G17 U_ UY plane. . . . . . . . .

Notes

A parameter is used to specify which axis, X, Y, or Z the
additional axis is parallel to. The move command functions
regardless of the plane selection.
For example, suppose that the following is specified:

G17 Z_ ;

Axis Z does not exist on the XpYp plane. The XY plane is
just selected, and the Z axis is moved regardless of the
plane.

ABSOLUTE AND INCREMENTAL PROGRAMMING (G90, G91)

There are two ways to command travels to the axes; the absolute
command, and the incremental command. In the absolute command,
coordinate value of the end point is programmed; in the incremental
command, move distance of the axis itself is programmed.
G90 and G91 are used to command absolute or incremental command.

G90 : Absolute command
G91 : Incremental command

Y

For the above figure, incremental command programming results in:

G91 X60.0 Y40.0 ;

while absolute command programming results in:

G90 X40.0 Y70.0 ;
Absolute/incremental command, when G code system A at T series is
selected, is not distinguished by G90/G91 but is distinguished by the
address word.
For the A and B axes, no incremental commands are provided.

POLAR COORDINA TE COMMAND (G15, G16)

(M SERIES)

Examples

The end point coordinate value can be input in polar coordinates (radius
and angle). Use G15, G16 for polar coordinates command.

G15 : Polar coordinate system command cancel
G16 : Polar coordinate system command

Plane selection of the polar coordinates is done same as plane selection
in circular interpolation, using G17, G18, G19.
Command radius in the first axis of the selected plane, and angle in the
second axis. For example, when the X-Y plane is selected, command
radius with address X, and angle with address Y . The plus direction of the
angle is counter clockwise direction of the selected plane first axis +
direction, and the minus direction the clockwise direction.
Both radius and angle can be commanded in either absolute or
incremental command (G90, G91).
The center of the polar coordinates is the zero point of the workpiece
coordinates. (However, if the local coordinates are set, it is the zero point
of the local coordinates.)

Conversion of inch and metric input can be commanded by the G code
command.

G20 : Inch input
G21 : Metric input

Whether the output is in inch system or metric system is parameter-set
when the machine is installed.
Command G20, G21 at the head of the program.
Inch/metric conversation can also be done by MDI setting.
The contents of setting data differs depending on whether G20 or G21 is
commanded.

Numerals can be input with decimal points. Decimal points can be used
basically in numerals with units of distance, speed, and angle. The
position of the decimal point is at the mm, inch, deg position.
There are two types of decimal point notation: calculator–type notation
and standard notation.
When calculator–type decimal notation is used, a value without decimal
point is considered to be specified in millimeters, inch or deg. When
standard decimal notation is used, such a value is considered to be
specified in least input increments.
Use parameters to select input method; whether to input by pocket
calculator type input, or by the usual decimal point input.
Values can be specified both with and without decimal point in a single
program.

LINEAR AXIS AND ROTATION AXIS

ROTATION AXIS
ROLL-OVER
FUNCTION

A linear axis refers to an axis moving linearly, and for it values are
specified in mm or inches.
A rotation axis refers to a rotating axis, and for it values are specified in
degrees.
For rotation axes, note the following:

 Inch-metric switching is not performed.
 The machine coordinate system is always normalized to the range

from 0deg to 360deg.

The rotation axis roll-over function rounds the absolute coordinate value
and relative coordinate value of a rotation axis to a coordinate value
within one rotation. This prevents coordinate values to overflow.
In an incremental command, the specified value is regarded as the amount
of travel.
In an absolute command, the specified value is rounded to within one
rotation. The resulting coordinate value is used as the end point. A
parameter is used to specify whether to determine the move direction by
the sign of the specified value or by the move distance (the shortest move
distance to the end point is selected).
