5309-E P-(i)SAFETY PRECAUTIONS

SAFETY PRECAUTIONSThe machine is equipped with safety devices which serve to protect personnel and the machine itself fromhazards arising from unforeseen accidents. However, operators must not rely exclusively on these safetydevices: 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 whichOkuma can predict. Be aware that they do not cover all possible hazards.

1. Precautions Relating to Installation(1) Please be noted about a primary power supply as follows.

• Do not draw the primary power supply from a distribution panel that also supplies a majornoise source (for example, an electric welder or electric discharge machine) since thiscould cause malfunction of the CNC unit.

• If possible, connect the machine to a ground not used by any other equipment. If there isno choice but to use a common ground, the other equipment must not generate a largeamount of noise (such as an electric welder or electric discharge machine).

(2) Installation EnvironmentObserve the following points when installing the control enclosure.

• 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 excessivevibrations 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. Points to Check before Turning on the Power(1) Close all the doors of the control enclosure and operation panel to prevent the entry of water,

chips, and dust.

(2) Make absolutely sure that there is nobody near the moving parts of the machine, and that thereare 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 CONTROLON switch on the operation panel.

5309-E P-(ii)SAFETY PRECAUTIONS

3. Precautions Relating to Operation(1) After turning on the power, carry out inspection and adjustment in accordance with the daily

inspection procedure described in this instruction manual.

(2) Use tools whose dimensions and type are appropriate for the work undertaken and the machinespecifications. 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 thespindle 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. Alwaysstop 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 themachine with any of the covers removed unless it is necessary to do so.

(8) Always stop the machine before mounting or removing a tool.

(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.

4. Precautions Relating to the ATC(1) The tool clamps of the magazine, spindle, etc., are designed for reliability, but it is possible that

a tool could be released and fall in the event of an unforeseen accident, exposing you todanger: do not touch or approach the ATC mechanism during ATC operation.

(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 causemisoperation. Do not use compressed air to remove these chips since it will only push the chipsfurther in.

(4) If the ATC stops during operation for some reason and it has to be inspected without turning thepower 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 themain power disconnect switch.

5309-E P-(iii)SAFETY PRECAUTIONS

6. Precautions during Maintenance Inspection and When Trouble OccursIn order to prevent unforeseen accidents, damage to the machine, etc., it is essential to observe thefollowing points when performing maintenance inspections or during checking when trouble hasoccurred.

(1) When trouble occurs, press the emergency stop button on the operation panel to stop themachine.

(2) Consult the person responsible for maintenance to determine what corrective measures needto be taken.

(3) If two or more persons must work together, establish signals so that they can communicate toconfirm safety before proceeding to each new step.

(4) Use only the specified replacement parts and fuses.

(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 wereand secure them properly with their screws, etc.

(7) When carrying out inspections in which measuring instruments are used - for example voltagechecks - 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 currentleakage and electric shocks.

(10) Maintenance inside the Control Enclosure

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 inthe MCS drive unit (servo/spindle), and for this reason only service personnel are permittedto perform any work on this unit. Even then, they must observe the following precautions.

• MCS drive unit (servo/spindle)The residual voltage discharges two minutes after the main switch is turned OFF.

c. The control enclosure contains the NC unit, and the NC unit has a printed circuit boardwhose memory stores the machining programs, parameters, etc. In order to ensure that thecontents of this memory will be retained even when the power is switched off, the memoryis supplied with power by a battery. Depending on how the printed circuit boards arehandled, the contents of the memory may be destroyed and for this reason only servicepersonnel should handle these boards.

5309-E P-(iv)SAFETY PRECAUTIONS

(11) Periodic Inspection of the Control Enclosure

a. Cleaning the cooling unitThe cooling unit in the door of the control enclosure serves to prevent excessivetemperature rise inside the control enclosure and increase the reliability of the NC unit.Inspect the following points every three months.

• Is the fan motor inside the cooling unit working?The motor is normal if there is a strong draft from the unit.

• Is the external air inlet blocked?If it is blocked, clean it with compressed air.

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 sufficienttraining.

(3) Make sure that your clothes and hair cannot become entangled in the machine. Machineoperators must wear safety equipment such as safety shoes and goggles.

2. Chuck (jig) pressure switching

2-1. No. 1 chuck (jig)

(1) OutlineThe clamping pressure for the first chuck (jig) can be switched between high and low levels.

• If the Chuck Clamp command is given using the pushbutton or code M148 or from therobot/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 thepressure from the low to the high level.Giving the Chuck Clamp command using the pushbutton or from the robot/loader with theworkpiece clamped at the low pressure does not changes the pressure.

• Giving the Chuck Unclamp command using the pushbutton or code M149 or from therobot/loader also gives the high pressure command.

• An M code command for low pressure clamping (M385) has been added. The ChuckClamp command accompanies the low pressure command.

(2) Conditions for supporting the functionThe chuck pressure switching function is supported when the fixture control is effective and thefollowing parameter set to "1."

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.

Machine user parameter No.15-3 CHUCK, SIT CONFIRMATION, TAILSTOCK27 High/low chuck pressure is made switchable.

0...Chuck pressure is not switchable.1...Check pressure is switchable.

2. Operation door closing operation with both hands

2-1. Linking the dual-palm starting and operation door closing sequences

To prevent inadvertent operations and ensure the safety, the system can only be started by pressingtwo start buttons with both hands. The two pushbuttons include the NC Start and dual-palm startbuttons.The start command and operation door closing sequence are linked with each other to eliminate theneed for closing the operation door and improve the operability.When the operation door is closed, the safety, which is the purpose of the dual-palm start button,has been ensured and the system can be started with one hand as in usual cases.

(1) Pre-requisite conditionsThe dual-palm start button is effective under the condition described below.The operation door is open in the automatic operation mode and either of the followingconditions exists.

• Starting at the head of the program.

• Starting after M00/M01.

Note that the dual-palm start button is ineffective under the condition described beloweven if the above conditions are met.

• The "robot/loader standby position" (iRTRF_b) has been set to "0" for type B or Crobot/loader interface in the linked mode.With machine user parameter "Robot/loader interface," 2 "Makes cycle start & robotstandby position interlock ineffective" set to "1," the above condition will beignored.

(2) SpecificationsIf both the NC Start button and dual-palm start button are pressed, the operation door closes.After the door completely closes (the "Door Close" LS turns on), the both inputs turn off to startthe NC.The NC Start button and dual-palm start button input signals should turn on/off one second lateror earlier than the other.

Note

ME61048R0200600050001

This function is only effective when the operation door is not closed. With the door closed, single-palm starting applies as in usual cases.


a. Turning-on timing of NC Start and dual-palm start buttonsThe one should be pressed within a second after the other is pressed. The door closes ifboth are pressed within a second.If the one is not pressed within a second after the other is pressed, the operation door doesnot close and the NC does not start. In this case, the following alarm message appears.

This alarm is released when both pushbutton inputs turn off.

b. Turning-off timing of NC Start and dual-palm start buttonsWith the operation door closed, the one should be pressed within a second after the otheris pressed. The NC starts if both are pressed within a second.If the one is not pressed within a second after the other is pressed, the NC does not start(the operation door remains closed). In this case, the following alarm message appears(after the elapse of one second).

This alarm is released when the NC is reset or started next as described below.(As the operation door has been closed, the NC can be started next with one hand only.)

ME61048R0200600050002

c. If either turns off before the operation door completely closes (the "Door Closed" LS turnson), the door stops closing and starts opening to prevent the NC from starting.

"4727 Alarm D Dual palm cycle start 1"

Code 1: The two start pushbuttons do not become activated within one second.

"4727 Alarm D Dual palm cycle start 2"

Code 2: The two start pushbuttons do not become inactivated within one second.


(3) Sequences under special conditions

a. If the door closing sequence is not linked, the NC Start signal turns on without performingthe door closing sequence.[Prerequisite conditions]This applies under the following conditions with the operation door open.

• Starting in the MDI mode.

• Starting in the manual operation mode.

• One of the following conditions exists in the automatic operation mode.

• Starting with the machine locked.

• Starting by sequence number search or cursor search.

• Starting after completion of block search by return search operation with thepredominant sequence return function.

• Starting after internal operation stop by the predominant sequence return func-tion.

• Starting after sequence return.

• Starting with Single Block on.

• Starting after a pause.

[Content of sequence]A signal rise triggers the start.The off-timing is not checked. Only the on-timing is checked.

ME61048R0200600050003

b. Single-palm startingWith the door closed, the NC starts when the NC Start button is pressed.

• The dual-palm start button input will be ignored.(The NC does not start if the dual-palm start button is pressed.)

• For type S door interlock, the NC does not start if the NC Start button is pressed afterpower-up with the door closed.

* Note that, for starting at the head of the program or after M00/M11, the door closes as usual even with Single Block on.


c. For type B or C robot/loader interfaceFor the conditions for starting via the robot/loader interface, see Section 1 "Specificationsfor Robot/loader Interface."

2-2. Operation door closing operation with both hands

(1) OutlineThe door close pushbuttons should need to be operated with both hands to prevent entangle-ment by the door.The two pushbuttons include the Door Close and dual-palm start buttons.

Note

(2) SpecificationsIf the time lag between the two inputs used for dual-palm door closing operation does notexceed one second, the Door Close signal turns on.If either or both of the two inputs turn off before the "Door Closed" LS turns on, the "DoorClosed" LS remains off and the Door Open signal turns on.After the "Door Closed" LS turns on, the Door Close signal remains on regardless of the statusof the two inputs.If the time lag between the two inputs used for dual-palm door closing operation exceeds onesecond, the following alarm message appears and the operation door does not close.

(3) Door status monitoringIf the relevant limit switch does not respond to the Door Open/Close command (Door Open/Close SOL) within the time preset by the parameter, the following alarm message appears andthe Door Open/Close SOL turns off.

Commands: Set and AddDefault: 0Min. value: 1Max. value: 600Programmable unit: 0.1 sec

If the parameter is set to 0, it will be reset to the maximum value (600).


2-3. Ineffective M code commands

For the system where dual-palm starting and door closing sequences are linked, the door closingsequence starts as the dual-palm start button is pressed and, after confirmation of the door closedcondition, the Program Start command is accepted.Therefore, the M code Door Close command in the program becomes unnecessary.The M code command is made ineffective to prevent entanglement, which would occur if the M codeDoor Close command remains effective.[Specifications]The M code Door Close command (M32) is ignored without raising an alarm (immediatelyanswered).Note that the M code Door Close command (M32) remains effective for the robot/loader inter-face type in the linked mode.Note that the M code Door Open command remains effective in any case.

3. Prevention of entanglement by automatic operation doorA rubber switch is provided at the contact part of the door edge and its status is continuously moni-tored to prevent entanglement by the operation door.

3-1. Content of sequence

(1) Front safety rubber switch check upon the issue of Door Close commandIf entanglement has been detected when the Door Close command is given, the following alarmmessage appears and the door does not close regardless of the operation mode.

(2) Front safety rubber switch check during door closing sequenceIf entanglement is detected during the door closing sequence, the door stops closing and startsopening regardless of the operation mode.

• The door opening sequence ends when the "Door Open" LS turns on or the RESET buttonis pressed.

• After the door opening sequence is cancelled by the rubber safety door switch:

a. If the M code Door Close command is given:If the Open command is given from the robot/loader:

b. If the Door Close command is given using the pushbutton, no alarm is raised.When the door opening sequence is triggered by the rubber safety door switch input,the door continues to open until the "Door Open" LS turns on regardless of thepushbutton status.

1-1. Related Commands

The semi-dry coolant discharge can be specified with “the M code command and RT command inthe same block” or “manual operation”.Regardless of whether the command is given with M code or by manual operation, the last-specifiedcommand remains effective.

1-2. M Code Command and RT Command in the Same Block

1-2-1. M Code Commands

1-2-2. RT Command

On receiving an RT command, the machine turns ON and OFF the pump-driving solenoid valve andsupplies 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 blockwhich includes M285 in the part program.The larger is the RT command value, the more frequent is the pump operation. This results inincrease in the oil supply amount.

[Example command format]M285 RT=4

Improper Command Alarm

If the RT value is less than 1 or larger than 10, the following alarm occurs and retains the RTcommand specified before occurrence of the alarm.
