GENERAL WARNINGS AND CAUTIONS

WARNING

1.

Never attempt to machine a workpiece without first checking the operation of the machine.
Before starting a production run, ensure that the machine is operating correctly by performing
a trial run using, for example, the single block, feedrate override, or machine lock function or
by operating the machine with neither a tool nor workpiece mounted. Failure to confirm the
correct operation of the machine may result in the machine behaving unexpectedly, possibly
causing damage to the workpiece and/or machine itself, or injury to the user.

2.

Before operating the machine, thoroughly check the entered data.
Operating the machine with incorrectly specified data may result in the machine behaving
unexpectedly, possibly causing damage to the workpiece and/or machine itself, or injury to the
user.

3.

Ensure that the specified feedrate is appropriate for the intended operation. Generally , for each
machine, there is a maximum allowable feedrate. The appropriate feedrate varies with the
intended operation. Refer to the manual provided with the machine to determine the maximum
allowable feedrate. If a machine is run at other than the correct speed, it may behave
unexpectedly, possibly causing damage to the workpiece and/or machine itself, or injury to the
user.

4.

When using a tool compensation function, thoroughly check the direction and amount of
compensation.
Operating the machine with incorrectly specified data may result in the machine behaving
unexpectedly, possibly causing damage to the workpiece and/or machine itself, or injury to the
user.

5.

The parameters for the CNC and PMC are factory–set. Usually, there is not need to change them.
When, however, there is not alternative other than to change a parameter, ensure that you fully
understand the function of the parameter before making any change.
Failure to set a parameter correctly may result in the machine behaving unexpectedly, possibly
causing damage to the workpiece and/or machine itself, or injury to the user.

6.

Immediately after switching on the power, do not touch any of the keys on the MDI panel until
the position display or alarm screen appears on the CNC unit.
Some of the keys on the MDI panel are dedicated to maintenance or other special operations.
Pressing any of these keys may place the CNC unit in other than its normal state. Starting the
machine in this state may cause it to behave unexpectedly.

7.

The operator’s manual and programming manual supplied with a CNC unit provide an overall
description of the machine’s functions, including any optional functions. Note that the optional
functions will vary from one machine model to another. Therefore, some functions described
in the manuals may not actually be available for a particular model. Check the specification of
the machine if in doubt.

WARNING

8.

Some functions may have been implemented at the request of the machine–tool builder. When
using such functions, refer to the manual supplied by the machine–tool builder for details of their
use and any related cautions.

NOTE

Programs, parameters, and macro variables are stored in nonvolatile memory in the CNC unit.
Usually, they are retained even if the power is turned off. Such data may be deleted inadvertently,
however, or it may prove necessary to delete all data from nonvolatile memory as part of error
recovery.
To guard against the occurrence of the above, and assure quick restoration of deleted data, backup
all vital data, and keep the backup copy in a safe place.

WARNINGS AND CAUTIONS RELATED TO
PROGRAMMING

This section covers the major safety precautions related to programming. Before attempting to
perform programming, read the supplied operator’s manual and programming manual carefully
such that you are fully familiar with their contents.

WARNING

1.

Coordinate system setting

If a coordinate system is established incorrectly, the machine may behave unexpectedly as a
result of the program issuing an otherwise valid move command.
Such an unexpected operation may damage the tool, the machine itself, the workpiece, or cause
injury to the user.

2.

Positioning by nonlinear interpolation

When performing positioning by nonlinear interpolation (positioning by nonlinear movement
between the start and end points), the tool path must be carefully confirmed before performing
programming.
Positioning involves rapid traverse. If the tool collides with the workpiece, it may damage the
tool, the machine itself, the workpiece, or cause injury to the user.

3.

Function involving a rotation axis

When programming polar coordinate interpolation or normal–direction (perpendicular) control,
pay careful attention to the speed of the rotation axis. Incorrect programming may result in the
rotation axis speed becoming excessively high, such that centrifugal force causes the chuck to
lose its grip on the workpiece if the latter is not mounted securely.
Such mishap is likely to damage the tool, the machine itself, the workpiece, or cause injury to
the user.

4.

Inch/metric conversion

Switching between inch and metric inputs does not convert the measurement units of data such
as the workpiece origin offset, parameter, and current position. Before starting the machine,
therefore, determine which measurement units are being used. Attempting to perform an
operation with invalid data specified may damage the tool, the machine itself, the workpiece, or
cause injury to the user.

5.

Constant surface speed control

When an axis subject to constant surface speed control approaches the origin of the workpiece
coordinate system, the spindle speed may become excessively high. Therefore, it is necessary
to specify a maximum allowable speed. Specifying the maximum allowable speed incorrectly
may damage the tool, the machine itself, the workpiece, or cause injury to the user.

SAFETY PRECAUTIONS

B–63002EN/02

s–6

WARNING

6.

Stroke check

After switching on the power, perform a manual reference position return as required. Stroke
check is not possible before manual reference position return is performed. Note that when stroke
check is disabled, an alarm is not issued even if a stroke limit is exceeded, possibly damaging
the tool, the machine itself, the workpiece, or causing injury to the user.

7.

Tool post interference check

A tool post interference check is performed based on the tool data specified during automatic
operation. If the tool specification does not match the tool actually being used, the interference
check cannot be made correctly, possibly damaging the tool or the machine itself, or causing
injury to the user.
After switching on the power, or after selecting a tool post manually, always start automatic
operation and specify the tool number of the tool to be used.

8.

Absolute/incremental mode

If a program created with absolute values is run in incremental mode, or vice versa, the machine
may behave unexpectedly.

9.

Plane selection

If an incorrect plane is specified for circular interpolation, helical interpolation, or a canned cycle,
the machine may behave unexpectedly . Refer to the descriptions of the respective functions for
details.

10.

Torque limit skip

Before attempting a torque limit skip, apply the torque limit. If a torque limit skip is specified
without the torque limit actually being applied, a move command will be executed without
performing a skip.

11.

Programmable mirror image

Note that programmed operations vary considerably when a programmable mirror image is
enabled.

12.

Compensation function

If a command based on the machine coordinate system or a reference position return command
is issued in compensation function mode, compensation is temporarily canceled, resulting in the
unexpected behavior of the machine.
Before issuing any of the above commands, therefore, always cancel compensation function
mode.

WARNINGS AND CAUTIONS RELA TED TO HANDLING

This section presents safety precautions related to the handling of machine tools. Before attempting
to operate your machine, read the supplied operator’s manual and programming manual carefully,
such that you are fully familiar with their contents.

WARNING

1.

Manual operation

When operating the machine manually , determine the current position of the tool and workpiece,
and ensure that the movement axis, direction, and feedrate have been specified correctly.
Incorrect operation of the machine may damage the tool, the machine itself, the workpiece, or
cause injury to the operator.

2.

Manual reference position return

After switching on the power, perform manual reference position return as required. If the
machine is operated without first performing manual reference position return, it may behave
unexpectedly . Stroke check is not possible before manual reference position return is performed.
An unexpected operation of the machine may damage the tool, the machine itself, the workpiece,
or cause injury to the user.

3.

Manual numeric command

When issuing a manual numeric command, determine the current position of the tool and
workpiece, and ensure that the movement axis, direction, and command have been specified
correctly, and that the entered values are valid.
Attempting to operate the machine with an invalid command specified may damage the tool, the
machine itself, the workpiece, or cause injury to the operator.

4.

Manual handle feed

In manual handle feed, rotating the handle with a large scale factor , such as 100, applied causes
the tool and table to move rapidly. Careless handling may damage the tool and/or machine, or
cause injury to the user.

5.

Disabled override

If override is disabled (according to the specification in a macro variable) during threading, rigid
tapping, or other tapping, the speed cannot be predicted, possibly damaging the tool, the machine
itself, the workpiece, or causing injury to the operator.

6.

Origin/preset operation

Basically, never attempt an origin/preset operation when the machine is operating under the
control of a program. Otherwise, the machine may behave unexpectedly, possibly damaging the
tool, the machine itself, the tool, or causing injury to the user.

SAFETY PRECAUTIONS

B–63002EN/02

s–8

WARNING

7.

Workpiece coordinate system shift

Manual intervention, machine lock, or mirror imaging may shift the workpiece coordinate
system. Before attempting to operate the machine under the control of a program, confirm the
coordinate system carefully.
If the machine is operated under the control of a program without making allowances for any shift
in the workpiece coordinate system, the machine may behave unexpectedly, possibly damaging
the tool, the machine itself, the workpiece, or causing injury to the operator.

8.

Software operator ’s panel and menu switches

Using the software operator’s panel and menu switches, in combination with the MDI panel, it
is possible to specify operations not supported by the machine operator’s panel, such as mode
change, override value change, and jog feed commands.
Note, however, that if the MDI panel keys are operated inadvertently, the machine may behave
unexpectedly, possibly damaging the tool, the machine itself, the workpiece, or causing injury
to the user.

9.

Manual intervention

If manual intervention is performed during programmed operation of the machine, the tool path
may vary when the machine is restarted. Before restarting the machine after manual intervention,
therefore, confirm the settings of the manual absolute switches, parameters, and
absolute/incremental command mode.

10.

Feed hold, override, and single block

The feed hold, feedrate override, and single block functions can be disabled using custom macro
system variable #3004. Be careful when operating the machine in this case.

11.

Dry run

Usually, a dry run is used to confirm the operation of the machine. During a dry run, the machine
operates at dry run speed, which differs from the corresponding programmed feedrate. Note that
the dry run speed may sometimes be higher than the programmed feed rate.

12.

Cutter and tool nose radius compensation in MDI mode

Pay careful attention to a tool path specified by a command in MDI mode, because cutter or tool
nose radius compensation is not applied. When a command is entered from the MDI to interrupt
in automatic operation in cutter or tool nose radius compensation mode, pay particular attention
to the tool path when automatic operation is subsequently resumed. Refer to the descriptions of
the corresponding functions for details.

13.

Program editing

If the machine is stopped, after which the machining program is edited (modification, insertion,
or deletion), the machine may behave unexpectedly if machining is resumed under the control
of that program. Basically, do not modify, insert, or delete commands from a machining program
while it is in use.

WARNINGS RELA TED TO DAILY MAINTENANCE

WARNING

1.

Memory backup battery replacement

When replacing the memory backup batteries, keep the power to the machine (CNC) turned on,
and apply an emergency stop to the machine. Because this work is performed with the power
on and the cabinet open, only those personnel who have received approved safety and
maintenance training may perform this work.
When replacing the batteries, be careful not to touch the high–voltage circuits (marked

and
fitted with an insulating cover).
Touching the uncovered high–voltage circuits presents an extremely dangerous electric shock
hazard.

NOTE

The CNC uses batteries to preserve the contents of its memory, because it must retain data such as
programs, offsets, and parameters even while external power is not applied.
If the battery voltage drops, a low battery voltage alarm is displayed on the machine operator’s panel
or screen.
When a low battery voltage alarm is displayed, replace the batteries within a week. Otherwise, the
contents of the CNC’s memory will be lost.
Refer to the maintenance section of the operator’s manual or programming manual for details of the
battery replacement procedure.

The FANUC Series 16i, 160i, 18i, 180i, 21i, and 210i are super–compact
ultra–thin CNC models with built–in liquid crystal displays. Each CNC
unit is a mere 60 mm deep and features, immediately behind the liquid
crystal display, a small CNC printed circuit board developed by utilizing
state–of–the–art LSI and surface–mount technologies.
Super–compact ultra–thin open CNC models are also available. The
CNC printed circuit board incorporates PC functions that are fully
compatible with the IBM PC(*).
The amount of cabling in the electrical unit of the machine can be
significantly reduced by using a high–speed serial servo bus, which
connects the CNC control unit and multiple servo amplifiers by a single
optical fiber cable. Another innovation which simplifies the electrical
unit of the machine tool is the use of compact distributed I/O modules,
which can be separately mounted on the machine operator’s panel and
control panel.

Helical interpolation performs circular interpolation of a maximum of
two axes, synchronizing with other optional two axes circular
interpolation. Thread cutting of large radius threads or machining of solid
cams are possible by moving a tool in a spiral.
The commanded speed is the speed of the tangential direction of the arc.
Thus, the speed of a linear axis is expressed as follows:

Helical interpolation B moves the tool in a helical manner. This
interpolation can be executed by specifying the circular interpolation
command together with up to four additional axes in simple
high–precision contour control mode.

Basically, the command can be specified by adding two movement axes
to a standard helical interpolation command (see Section 3.5). Address
F should be followed by a tangential velocity, which has been determined
by also taking movement along the linear axes into consideration.

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

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.

The polar coordinate interpolation cancel mode is obtained by G13.1
command.

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

 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.

In helical interpolation, when pulses are distributed with one of the
circular interpolation axes set to a hypothetical axis, sine interpolation is
enable.
When one of the circular interpolation axes is set to a hypothetical axis,
pulse distribution causes the speed of movement along the remaining axis
to change sinusoidally. If the major axis for threading (the axis along
which the machine travels the longest distance) is set to a hypothetical
axis, threading with a fractional lead is enabled. The axis to be set as the

Many computer–aided design (CAD) systems used to design metal dies
for automobiles and airplanes utilize non–uniform rational B–spline
(NURBS) to express a sculptured surface or curve for the metal dies.

This function enables NURBS curve expression to be directly specified
to the CNC. This eliminates the need for approximating the NURBS
curve with minute line segments. This offers the following advantages:

1. No error due to approximation of a NURBS curve by small line
segments

2. Short part program

3. No break between blocks when small blocks are executed at high
speed

4. No need for high–speed transfer from the host computer to the CNC

When this function is used, a computer–aided machining (CAM) system
creates a NURBS curve according to the NURBS expression output from
the CAD system, after compensating for the length of the tool holder, tool
diameter, and other tool elements. The NURBS curve is programmed in
the NC format by using these three defining parameters: control point,
weight, and knot.

NURBS interpolation while smoothly accelerating or decelerating the
movement so that the acceleration on each axis will not exceed the
allowable maximum acceleration of the machine. In this way, the CNC

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.
The following shows the specifiable lead range:

Rapid traverse rate can be overridden by:

F0, 25%, 50%, 100%.

F0: A constant speed per axis can be set by parameter

An override of 0% to 100% can be applied in 1% steps using a signal.

Feed rate override and the second feed rate override can be clamped to
100% by a signal from the machine side.

The manual continuous feedrate and incremental feed rate can be
overridden by:
0% to 655.34% (in steps of 0.01%)

Acceleration and deceleration is performed when starting and ending
movement, resulting in smooth start and stop.
Automatic acceleration/deceleration is also performed when feed rate
changes, so change in speed is also smoothly done.

The function for rapid traverse bell–shaped acceleration/deceleration
increases or decreases the rapid traverse feedrate smoothly.
This reduces the shock to the machine system due to changing
acceleration when the feedrate is changed.
As compared with linear acceleration/deceleration, bell–shaped
acceleration/deceleration allows smaller time constants to be set,
reducing the time required for acceleration/deceleration.

In the linear acceleration/deceleration, the delay for the command caused
by the acceleration/ deceleration becomes 1/2 compared with that in
exponential acceleration/deceleration, substantially reducing the time
required for acceleration and deceleration.
Also, the radius direction error in the circular interpolation caused by the
acceleration/deceleration is substantially reduced.

As shown above in the quadratic curve, it is possible to accelerate and
decelerate the cutting feedrate.
When the acceleration and deceleration section are connected, the
composed curve shapes just like a hanging bell. That is why this kind of
acceleration/deceleration is called bell–shaped acceleration/deceleration.
Considering a time constant as Tc (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
acceleration/deceleration curve 0A shown in the figure above can be
expressed by the following equation :

The curve AB and 0A are symmetric with respect to point A.
The feature of this acceleration/deceleration is that the feedrate change is

Generally, the CNC does not zero the feedrate at the interface of two
blocks during cutting feed.
Because of this, a corner of a tool path may be rounded.

If the error detect signal is used, it is possible to specify that

of the previous block has been completed.

NOTE

If the error detect signal is on, a cutting block is not executed
until the acceleration/deceleration of the previous cutting
block has been completed.
This function alone cannot prevent corner rounding due to
delay caused by the servo motor, however.
To prevent corner rounding due to delay caused by the
servo motor, use the in–position check function together

Move command in blocks commanded with G09 decelerates at the end
point, and in–position check is performed. G09 command is not
necessary for deceleration at the end point for positioning (G00) and
in–position check is also done automatically. This function is used when
sharp edges are required for workpiece corners in cutting feed.

Exact stop on (The in-position
check is performed at the end of
a block.)

Exact stop off

When G61 is commanded, deceleration of cutting feed command at the
end point and in–position check is performed per block thereafter. This
G61 is valid till G64 (cutting mode), G62 (automatic corner override), or
G63 (tapping mode) is commanded.

When G64 is commanded, deceleration at the end point of each block
thereafter is not performed and cutting goes on to the next block. This
command is valid till G61 (exact stop mode), G62 (automatic corner
override), or G63 (tapping mode) is commanded.

When G63 is c o m m anded, feed rate override is ignored (always regarded
as 100%), and feed hold also becomes invalid. Cutting feed does not
decelerate at the end of block to transfer to the next block. And in-tapping
signal is issued during tapping operation. This G63 is valid till G61
(exact stop mode), G62 (automatic corner override), or G64 (cutting
mode) is commanded.

When G62 is commanded during cutter compensation, cutting feed rate
is automatically overridden at corner. The cutting quantity per unit time
of the corner is thus controlled not to increase. This G62 is valid till G61
(exact stop mode), G64 (cutting mode), or G63 (tapping mode) is
commanded.

With the G04 command, shifting to the next block can be delayed.
When commanded with a per minute feed mode (G94), shifting to the next
block can be delayed for the commanded minutes.
When commanded with a per rotation feed mode (G95), shifting to the
next block can be delayed till the spindle rotates for the commanded
times.
Dwell may always be performed by time irrespective of G94 and G95 by
parameter selection.

When a rapid traverse command is specified during automatic operation,
the function for positioning by optimum acceleration can be used to adjust
the rapid traverse rate, time constant, and loop gain, according to the
amount of travel for the block. This reduces the time required for
positioning and position check, therefore reducing the cycle time.
When rapid traverse is specified in automatic operation, the function
adjusts the rapid traverse rate, time constant, and loop gain to one of seven
levels, according to the amount of travel for the block. The relationship
between the amount of travel and the corresponding rapid traverse rate,
time constant, and loop gain is specified in parameters. This function is
not effective for cutting feed.

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.
