SAFETY PRECAUTIONS
SAFETY PRECAUTIONS
The machine is equipped with safety devices which serve to protect personnel and the machine itself from
hazards arising from unforeseen accidents. However, operators must not rely exclusively on these safety
devices: they must also become fully familiar with the safety guidelines presented below to ensure accident-
free operation.
This instruction manual and the warning signs attached to the machine cover only those hazards which
Okuma can predict. Be aware that they do not cover all possible hazards.
• Do not draw the primary power supply from a distribution panel that also supplies a major
noise source (for example, an electric welder or electric discharge machine) since this
could cause malfunction of the CNC unit.
• If possible, connect the machine to a ground not used by any other equipment. If there is
no choice but to use a common ground, the other equipment must not generate a large
amount of noise (such as an electric welder or electric discharge machine).
• Make sure that the CNC unit will not be subject to direct sunlight.
• Make sure that the control enclosure will not be splashed with chips, water, or oil.
• Make sure that the control enclosure and operation panel are not subject to excessive
vibrations or shock.
• The permissible ambient temperature range for the control enclosure is 5 to 40°C.
• The permissible ambient humidity range for the control enclosure is relative humidity 50%
or less at 40°C (no condensation).
• The maximum altitude at which the control enclosure can be used is 1000 m (3281ft.).
(2) Make absolutely sure that there is nobody near the moving parts of the machine, and that there
are no obstacles around the machine, before starting machine operation.
(3) When turning on the power, turn on the main power disconnect switch first, then the CONTROL
ON switch on the operation panel.
5309-E P-(ii)
SAFETY PRECAUTIONS
(2) Use tools whose dimensions and type are appropriate for the work undertaken and the machine
specifications. Do not use badly worn tools since they can cause accidents.
(3) Do not, for any reason, touch the spindle or tool while spindle indexing is in progress since the
spindle could rotate: this is dangerous.
(4) Check that the workpiece and tool are properly secured.
(5) Never touch a workpiece or tool while it is rotating: this is extremely dangerous.
(6) Do not remove chips by hand while machining is in progress since this is dangerous. Always
stop the machine first, then remove the chips with a brush or broom.
(7) Do not operate the machine with any of the safety devices removed. Do not operate the
machine with any of the covers removed unless it is necessary to do so.
(9) Do not approach or touch any moving part of the machine while it is operating.
(10) Do not touch any switch or button with wet hands. This is extremely dangerous.
(11) Before using any switch or button on the operation panel, check that it is the one intended.
(2) Always inspect and change tools in the magazine in the manual magazine interrupt mode.
(3) Remove chips adhering to the magazine at appropriate intervals since they can cause
misoperation. Do not use compressed air to remove these chips since it will only push the chips
further in.
(4) If the ATC stops during operation for some reason and it has to be inspected without turning the
power off, do not touch the ATC since it may start moving suddenly.
5. On Finishing Work
(1) On finishing work, clean the vicinity of the machine.
(2) Return the ATC, APC and other equipment to the predetermined retraction position.
(3) Always turn off the power to the machine before leaving it.
(4) To turn off the power, turn off the CONTROL ON switch on the operation panel first, then the
main power disconnect switch.
5309-E P-(iii)
SAFETY PRECAUTIONS
(1) When trouble occurs, press the emergency stop button on the operation panel to stop the
machine.
(2) Consult the person responsible for maintenance to determine what corrective measures need
to be taken.
(3) If two or more persons must work together, establish signals so that they can communicate to
confirm safety before proceeding to each new step.
(5) Always turn the power off before starting inspection or changing parts.
(6) When parts are removed during inspection or repair work, always replace them as they were
and secure them properly with their screws, etc.
(7) When carrying out inspections in which measuring instruments are used - for example voltage
checks - make sure the instrument is properly calibrated.
(8) Do not keep combustible materials or metals inside the control enclosure or terminal box.
(9) Check that cables and wires are free of damage: damaged cables and wires will cause current
leakage and electric shocks.
a. Switch the main power disconnect switch OFF before opening the control enclosure door.
b. Even when the main power disconnect switch is OFF, there may some residual charge in
the MCS drive unit (servo/spindle), and for this reason only service personnel are permitted
to perform any work on this unit. Even then, they must observe the following precautions.
c. The control enclosure contains the NC unit, and the NC unit has a printed circuit board
whose memory stores the machining programs, parameters, etc. In order to ensure that the
contents of this memory will be retained even when the power is switched off, the memory
is supplied with power by a battery. Depending on how the printed circuit boards are
handled, the contents of the memory may be destroyed and for this reason only service
personnel should handle these boards.
5309-E P-(iv)
SAFETY PRECAUTIONS
7. General Precautions
(1) Keep the vicinity of the machine clean and tidy.
(2) Wear appropriate clothing while working, and follow the instructions of someone with sufficient
training.
(3) Make sure that your clothes and hair cannot become entangled in the machine. Machine
operators must wear safety equipment such as safety shoes and goggles.
(4) Machine operators must read the instruction manual carefully and make sure of the correct
procedure before operating the machine.
(5) Memorize the position of the emergency stop button so that you can press it immediately at any
time and from any position.
(6) Do not access the inside of the control panel, transformer, motor, etc., since they contain high-
voltage terminals and other components which are extremely dangerous.
(7) If two or more persons must work together, establish signals so that they can communicate to
confirm safety before proceeding to each new step.

SECTION 2 CHUCK (JIG) CONTROL
Note
If only the "Chuck Closed" LS is ineffective, the "Chuck Open" LS is checked in the chuck clamp/
unclamp sequences of 4) but the "Chuck Closed" LS is not.
Note
If only the "Chuck Open" LS is ineffective, the "Chuck Close" LS is checked in the chuck clamp/
unclamp sequences of 4) but the "Chuck Open" LS is not.
If both of the aforementioned parameters are set to "1" (both the "Chuck Closed" and "Chuck Open"
limit switches are ineffective), the sequence completes after the relevant SOL remains on for the
time preset by the timer after issue of the Chuck Clamp/Unclamp command.
It is more specifically described below.
(1) OD clamping
• The Chuck Clamp command turns the Chuck Open SOL off and the Chuck Close SOL on.
The workpiece is considered completely clamped after the work clamp timer (described
later) counts up.
• The Chuck Unclamp command turns the Chuck Close SOL off and the Chuck Open SOL
on. The workpiece is considered completely unclamped after the work unclamp timer
(described later) counts up.
(2) ID clamping
• The Chuck Clamp command turns the Chuck Close SOL off and the Chuck Open SOL on.

SECTION 2 CHUCK (JIG) CONTROL
ME61048R0200400060001
1-7. Interlocking
(1) Interlocking for inhibiting cutting feed
Cutting feed is inhibited when the workpiece has not been completely clamped.
Interlocking for cutting feed inhibition can be overridden using the following parameter.
(With the following parameter set to "1," cutting feed is permitted even when the workpiece has
not been completely clamped.)
MC UNSER PARAMETER No.15-1 CHUCK, SIT CONFIRMATION, TAILSTOCK
2 Even if the chuck opens, cutting feed remains executable.
0...Makes cutting feed executable even when the chuck is open.
1...Makes cutting feed inexecutable when the chuck is open.
The following diagnosis message appears when the aforementioned interlocking is active.
"15202 Chuck close LS in not ON."
Or, for some models:
"15204 Fixture clamp confirmation LS is not ON."
Note that this message only appears during NC operation or cutting process.
• With the following parameter set to "1," the SOL does not turn off even with alarm A pending or
in the power saving mode.
MC UNSER PARAMETER No.15 CHUCK, SIT CONFIRMATION, TAILSTOCK
23 Even if alarm A is pending or in the power saving mode, chuck SOL remains on.
0...Turns SOL off with alarm A pending or in the power saving mode.
1...Keeps SOL on with alarm A pending or in the power saving mode.
• If the Chuck Clamp command is given using the pushbutton or code M148 or from the
robot/loader with the workpiece unclamped, the workpiece is clamped at the high pressure.
• Giving the M148 command with the workpiece clamped at the low pressure changes the
pressure from the low to the high level.
Giving the Chuck Clamp command using the pushbutton or from the robot/loader with the
workpiece clamped at the low pressure does not changes the pressure.
• Giving the Chuck Unclamp command using the pushbutton or code M149 or from the
robot/loader also gives the high pressure command.
• An M code command for low pressure clamping (M385) has been added. The Chuck
Clamp command accompanies the low pressure command.
Purpose: A higher clamping force may deform the workpice and consequently affects the
machining accuracy. Using the high pressure for rough grinding and the low pres-
sure for finishing improves the machining accuracy.
(4) Sequences
The workpiece is considered completely clamped at the high pressure after the
"Chuck High Pressure Open" limit switch turns off and the "Chuck High Pres-
sure Closed" limit switch on and the work clamp timer (described later) counts
up.
Note that the workpiece is not considered completely clamped at the high pres-
sure if the "Chuck (jig) High Pressure Closed" limit switch remains off for 0.5
second or longer after the workpiece is completely clamped at the high pres-
sure.
(2) High pressure unclamp sequence
The High Pressure Unclamp command turns the Chuck Close SOL off and the
Chuck Open SOL on. At this time, the Low Pressure SOL turns off 0.3 second
later if it has been on.
The workpiece is considered completely clamped at the high pressure after the
"Chuck High Pressure Closed" limit switch turns off and the "Chuck High Pres-
sure Open" limit switch on and the work unclamp timer (described later) counts
up.
c. High pressure clamp, high pressure unclamp and low pressure clamp sequences (for ID
clamping)
The sequences for ID clamping are the same as for OD clamping except that the Open/
Close SOLs and LSs will have the opposite statuses as shown below.
OD clamping ID clamping
Chuck Open SOL Chuck Close SOL
Chuck Close SOL Chuck Open SOL
"Chuck High Pressure Open" LS "Chuck High pressure Closed" LS
"Chuck High Pressure Closed" LS "Chuck High Pressure Open" LS
"Chuck Low Pressure Open" LS "Chuck Low Pressure Closed" LS
"Chuck Low Pressure Closed" LS "Chuck Low Pressure Open" LS
(5) Parameters
a. The "Chuck Low Pressure Open/Closed" LSs can be made effective or ineffective using
the following parameters
Machine User Parameter No.15-3 CHUCK, SIT CONFIRMATION, TAILSTOCK
28 'Chuck Closed' Low PS is made ineffective.
0...Makes "Chuck Closed" low PS effective.
1...Makes "Chuck Closed" low PS ineffective.
• The statuses are retained even with alarm A pending, in the power saving mode or
RESET or MODE RESET pressed.
• For high pressure command: The workpiece is completely clamped by the chuck (jig)
at the high pressure.
• For low pressure command: The workpiece is completely clamped by the chuck (jig) at
the low pressure.
(8) Interlocking
• Each SOL remains off when alarm A has been pending or the power saved.
(The statuses are retained if the system is reset with RESET or RESET MODE.)
If alarm A is released, the power saving mode exited, or the system powered on, the sys-
tem returns to the status where alarm A has not been raised, the power saving mode not
entered, or the system not powered off.
• With the following parameter set to "1," the SOL does not turn off even with alarm A pend-
ing or in the power saving mode.
MC UNSER PARAMETER No.15 CHUCK, SIT CONFIRMATION, TAILSTOCK
23 Even if alarm A is pending or in the power saving mode, chuck SOL remains on.
0...Turns SOL off with alarm A pending or in the power saving mode.
1...Keeps SOL on with alarm A pending or in the power saving mode.
5309-E P-45
SECTION 2 CHUCK (JIG) CONTROL
Note
These commands are effective regardless of the System Link switch position.
The M00 and M01 commands also turn the Chuck Air Blow SOL off.
Note that this function can be switched using the following parameter.
Machine user parameter No.1-2 COOLANT
20 M00/M01 doesn't turn off the spindle/coolant group.
0...M00/M02 stop the spindle and coolant group.
1...M00/M01 do not stop the spindle and coolant group.
4. Input/output signals
Input bit
Output bit
1-1. M Codes
M code Content
M340 Work sit condition monitor ON
M341 Work sit condition monitor OFF.
Note
• With the workpiece unclamped, the M340 command does not turn the work sit condition monitor
on and will be immediately answered.
This only applies when the chuck is provided.
• The M340 command is immediately answered when the work sit condition monitor is on and the
M341 command is immediately answered when it is off.
• The commands are ignored and immediately answered when the machine has been locked.
(1) The M340 command starts the workpiece seating air blow (answered) and, after the timer (see
section 7 "Seating Timer") counts up, initiates the sit condition monitoring mode where the work
sit confirmation signal is checked.
(2) If the Chuck Clamp PB command is accepted with the sit condition monitor switch on, it starts
the workpiece seating air blow and, after the workpiece is completely clamped and the timer
(see section 7 "Seating Timer") counts up, initiates the sit condition monitoring mode where the
work sit confirmation signal is checked.
This only applies when the chuck is provided.
The sit condition monitor is activated in either of the aforementioned ways and operates as
described below depending on the status of the work sit confirmation signal at that time.
• If the work sit confirmation signal remains off for 0.5 sec or longer in the sit condition monitoring
mode with the spindle at rest and the NC active, the following alarm message appears.
" 2736 Alarm B Work clamp miss *** "
*** 2: The work sit confirmation signal 1 remained OFF for more than 0.5 seconds
when the spindle was at rest with the monitoring function ON.
*** 202: The work sit confirmation signal 2 remained OFF for more than 0.5 seconds
when the spindle was at rest with the monitoring function ON.
*** 302: The work sit confirmation signal 3 remained OFF for more than 0.5 seconds
when the spindle was at rest with the monitoring function ON.
• If the work sit confirmation signal remains off for 0.5 sec or longer in the sit condition monitoring
mode with the spindle at rest and the NC not active, the following alarm message appears.
" 4770 Alarm D Work clamp miss *** "
*** 2: The work sit confirmation signal 1 remained OFF for more than 0.5 seconds
when the spindle was at rest with the monitoring function ON.
*** 202: The work sit confirmation signal 2 remained OFF for more than 0.5 seconds
when the spindle was at rest with the monitoring function ON.
*** 302: The work sit confirmation signal 3 remained OFF for more than 0.5 seconds
when the spindle was at rest with the monitoring function ON.
* This alarm is available when a chuck (jig) and N seating sensors are supported by the
user's specifications.

seating air blow off when the sit condition monitor stops" is set to "1."
If the aforementioned parameter is set to "1," the sit condition monitoring mode is exited as
mentioned above. In this case, however, this parameter should be set back to "0."
This parameter is provided to forcibly exit the sit condition monitoring mode and thus release
the alarm when any seating error is detected.

Pressing the "Door Close" button with the operation door unlocked turns the "Door
Close" SOL on and the "Door Open" SOL off.
The operation door is considered completely closed when the "Door Closed" LS turns
on.
For pushbutton input commands, the last input one takes precedence.
The manually (PB) input Door Open/Close commands are always effective regardless of
the operation mode.

1. Semi-Dry Coolant
1-2-2. RT Command
On receiving an RT command, the machine turns ON and OFF the pump-driving solenoid valve and
supplies oil by the amount required for the purpose of machining.
The pump ON/OFF intervals (pump operation frequency) can be specified in 10 steps.
Command Format
Specify the RT command by entering RT=* (*: an integer between 1 and 10 inclusive) in the block
which includes M285 in the part program.
The larger is the RT command value, the more frequent is the pump operation. This results in
increase in the oil supply amount.
If the RT value is less than 1 or larger than 10, the following alarm occurs and retains the RT
command specified before occurrence of the alarm.
When the RT command is normally executed (without alarm 2874) by oil mist ON signal, the
machine turns ON and OFF the oil mist unit according to the RT command.
The initial RT command value is “4”.
When the power is turned OFF and then ON, the RT value becomes the value specified last.
The diagram below shows the pump ON/OFF timing at each RT value.

• When the above panel button is pressed, the machine turns off the semi-dry coolant output.
When this button is pressed again, the machine restarts discharging the semi-dry coolant.
• If the semi-dry coolant ON command is issued when all the coolants are stopped, the machine
ignores the command. In this case, press the ALL COOLANTS OFF button and then issue the
semi-dry coolant ON command.
* If the semi-dry coolant OFF command is issued before canceling the temporary stop of all
the coolants, the machine does not output the semi-dry coolant even if the ALL COOLANTS
OFF button is pressed.
• The coolant temporary stop ON/OFF state is backed up, and the last command remains
effective after the power is re-supplied.
