Functions in Auto Mode

Move machine to home position

Step 1:

The home position is the defined starting point for many NC programs. In the home position, the Z-slide is retracted and in the "Start position". Machining of the workpiece can be started from here.
Preconditions:

  • Drives and media switched on.
  • Channel 1 and 2 active.
  • Safety doors closed and locked.

Press OP Auto and Auto keys.
The machine is switched to automatic mode.

Step 2:

Press the Master Return key.
The machine moves to the home position.

  • The machine axes move to their home position.

    • The lamp comes on when the home position is reached.

Starting production

Step 1:

Preconditions:

  • Fixtures of the machine have been changed over to the workpiece type that is to be machined.
  • Axes in home position.
  • Drives and media switched on.
  • Safety doors closed and locked.
  • There is a raw workpiece on the load conveyor.
  • "Manual loading without automation" function is deselected.

Press the Interlinked Operation Mode (OP Auto) key.
The machine is included in the system linkage.

  • The lamp "OP AUTO" illuminates.
  • The "AUTO" NC mode is automatically selected. The "AUTO" lamp comes on.

Step 2:

Press the Start/Step key.

The machining program is initiated and the machine waits for a raw part, which is loaded into the work area via the pallet changer.

Step 3:

Preconditions:

- Pallet 1 (empty) at setting station.
- The setting station is in the 0° position.
- Workpiece loading station safety door closed.

Step 4:

Press the Unlock/*open safety door key.
The workpiece setting station safety door is opened.

Step 5:

Place a raw part on pallet 1 at the setting station.
Use lifting equipment for inserting the raw part!

Step 6:

Read the data matrix code for the raw part (e.g. DATALOGIC Powerscan).

Step 7:

Press the Preset Start key.
The "Preset start" lamp will illuminate if the read data matrix code is valid.

The pallet is released for the subsequent pallet change and for machining.
- The "Preset start" lamp flashes during the pallet change.
- The "Preset start" lamp then goes out.

Z-axis moves to the loading position. The right-hand display field is highlighted.

Step 2:

Unclamp Fixture

Step 3:

Open Front Door

Step 4:

If necessary, blow off chips from the fixture rest points.

Pick up new raw part using the hoist.
Position the hoist over the fixture and lower carefully.
Insert the workpiece into the fixture in the correct position. Observe the stops and indexing movements.
Run the hoist completely out of the safety door.

Step 5:

Close Front Door

-The Z-axis moves to the machining position.
-The machining program assigned in the type preselection is started.
-The "START" lamp remains on throughout the entire machining time.
-Once the workpiece has been completely machined, the Z-axis moves into the unloading position.

Take into consideration any messages from the control and, of mncessary, carry out the required actions.

Basic information

The warmup circuit enables a program to be started automatically every weekday (including Saturday and Sunday). This allows the machine to be run up to operating temperature before machining the first workpiece. Damage to the machine and workpiece can be reduced to a minimum and a high degree of machining accuracy achieved in the initial stages of production.

The warmup program is repeated until the maximum warmup period is over. Programs that run longer than the set maximum running time are however completely processed. The NC program is not restarted.

Open the "Warm-up program" window

Step 1:

Preconditions:

  • Drives and media switched on.
  • Safety doors closed and locked.
  • "Automatic" NC operating mode is activated.
  • "Machine" main menu activated.
  • The warmup program is stored in the NC.
  • No program is running.

Call up the machine's basic menu using the Data menu key.

Press the etc. key.

The basic menu is expanded in a horizontal direction.
The "warm-up" softkey is available.

Step 2:

Press the "Warmup" softkey.
The "Warm-up program" window opens.
The "Warm-up program" serves as the display. If you want to configure warm-up programs, you must switch to edit mode. In the "Automation" line, any NC program must be selected for warmup. In the example, the NC-program "WUP.MPF" is selected. Entries for the individual weekdays can remain empty.

Edit mode

Precondition:
- The "Warm-up program" window is open.

Press the "Edit" softkey.
Edit mode is opened.
Further softkeys are displayed.

Setting time

Step 1

Use the Cursor keys to select the input field for the hours display of the desired day of the week.

Use the Alphanumeric keys to enter the hour of the desired program start. (e.g.: 05)

Press the Tab key.
The cursor moves to the input field for the minutes display.

Use the Alphanumeric keys to enter the minutes of the desired program start. (e.g.: 25)

Select warmup program

The following restrictions apply for the warm-up program:
- The warm-up program must not contain an endless loop.
- The warm-up program must not initiate a pallet change.

NC programs from the parts program or any workpiece directories may be selected.
A "warm-up" workpiece, into which the warm-up programs can then be stored, is often created.

Step 1

Press Tab to select the "NC program" input field for the desired day of the week.
The "NC" softkey is enabled.

Step 2

Press the "NC" softkey.
The file directory opens.

If necessary open or close directory with the Enter.

Select the desired program using the Cursor keys.

Press the "Accept" softkey.
The selected NC program is accepted into the input field and the data selection menu is closed.

Incorrect file selected?
Use the Backspace key to remove the selected file. Another file can be selected as described above.

Start Warmup program

Use the Checkbox in the "active" column to switch the program for the day of the week on or off.

Example: the entered program should be started on Tuesday in future.

Step 1

Edit mode is open.

Press the "Tuesday" softkey.
The cursor moves to the checkbox for Tuesday.

Step 2

Press the Highlight key.
The checkbox is ticked.

Pressing the Selection key again will deactivate the warmup program (this is a toggle function).

The motors are switched-off at the end of the warmup via the internal function "Stop at end of shift", e.g. after 30 mins.

Setting maximum runtime

Step 1

The duration of the warmup sequence is entered in minutes in the "Runtime" field; valid values:
- Minimum warmup time: 3 min
- Maximum warmup time: 9999 min (167 h).

Edit mode is open.

Use the Cursor keys to select the "Runtime" input field.

Enter the warmup period (e.g. 15 minutes) using Alphanumeric keys.

Close edit mode

Step 1

Press the "Save" softkey.
The changes made will be accepted and saved. Edit mode is closed.

If you press the "Cancel" softkey, edit mode will close without saving the changes.

Important Hints

Pressing the Reset button during warmup interrupts the program.

The system time of the control must be checked on a regular basis and adjusted if necessary.

Information on tool spindle warmup

In order to guarantee even distribution of the lubrication oil after down times, you must prepare the spindle by warming-up.

To use the optionally expanded speed range, you must prepare the spindle by warming-up.

Details on spindle warm-up can be found in the Chapter on: "Restarting the machine after downtime"

Start warmup program

Step 1

Preconditions:

  • The machine must be in the home position.
  • Warm-up function must be activated in the "Cycle types" screen ("Prepare" area).

Press the Master Return key.
The machine moves to the home position.

Step 2

Press the Setup and Auto keys.
The warm-up program will begin when the start time has been reached.

Step 3

To indicate that a warm-up is currently running, the message "Warmup program active - cancel with reset or automatically once the setpoint time has expired at end of program" is displayed.
When the warm-up program is active, the following functions are disabled:

  • NC-start with activated OP AUTO mode.
  • NC-start for other programs.

Normal mode is possible again only when the cycle type "Preselect warm-up function" has been deselected.

Stopping the warm-up program manually

Step 1

The warm-up program stops either automatically or after the specified runtime or via manual intervention.

Press the Immediate Stop key.
The warmup program is stopped

Step 2

Switch-off warm-up function in the "Cycle types" HMI screen ("Prepare" area).

Press the Interlinked Operation Mode (OP Auto) key.
The machine is included in the system linkage.

Step 3

Also press the Master Return key.
The machine moves to the home position.

Step 4

Press the Start/Step key.
The machine now runs again with the normal machining program.
