Switching to automatic loading

Workpieces are inserted directly into the fixture machine via the loading hatch (raw part) or removed from there (finished part). For the loading and unloading processes, the Z-axis of the machine travels to the loading position and the loading hatch is opened. The coordination for the loading and unloading processes is accomplished by the loader controller via the loader interface.

Deselecting the "Manual loading without automation" function switches the machine to automatic mode. Check, before starting fully-automatic production mode, whether the function in the "General" HMI screen is set as follows:

Step 1:

Checking the loader interface

The HMI "Interface" screen can be called in order to gain detailed insight into the automated loading and unloading of the machine via the loader. Individual interface signals are displayed, which can also be set manually if required.

Depending on the actual automation system, the HMI screen makes interface bits available on several pages. The incoming and outgoing signals are displayed in the left and right sides of the screen.

Incoming: Signals from loader
Outgoing: Signals from machine

home position

The home position is the defined starting point for many NC programs. In the home position, the axes move to their start position. Machining of the workpiece can be started from here.

Runout Machine

The basic sequence for loading and unloading workpieces in automatic production mode can be defined via the "Runout" HMI function.

Standard sequence: "Runout" deactivated

The machine is loaded with a new raw part.
When the workpiece has been machined, the machine is unloaded.
The machine is loaded with the next raw part.
etc.

Special sequence: "Runout" activated:

The current workpiece will be finish-machined and then unloaded.
No new workpiece will be loaded.

Activating runout

Step 1:

Starting the unloading operation

Step 1:

Step 2:

Deactivating runout again

Step 1:

If an irregularity was discovered or a tool fracture occurred during machining, the operator can systematically unload the workpiece. To do this, the workpiece status must be set manually to "NOK workpiece for unloading". This unqualified part (NOK part) is picked up by the loader and set down at a special location (e.g. SPC location).

Declaring workpiece as NOK part

Step 1:

Unloading NOK part

Step 1:

Step 2:

If malfunctions occur, the machine stops in its current position for safety reasons. An error message is displayed on the screen.
Once the cause of the malfunction has been remedied, you must confirm this in the "Acknowledge" HMI screen. No machine will not execute any further movements until you have done so.

Calling up the "Acknowledgment" HMI screen

Step 1:

Step 2:

Operation at the main operator panel or HT8

If operation is toggled between the stationary operator panel (main operator panel) and the mobile handheld operating unit (HT8), the mobile handheld operating unit can remain inserted on the main operator panel.

To transfer the command from the "mobile" to the "stationary" operator panel and vice versa, only the "Mobile handheld operating unit focus change" HMI function needs to be actuated.

Preconditions:

"Setup" machine mode is active.
"Acknowledge" HMI screen is opened.
The "HT8 Focus change" function is available.

Operation at the HT8

Step 1:

Operation at the main control panel

Step 1:

Reset machining depth

The control has a depth marker for re-entry into the last machining step.

Please refer to programming instructions (PA) in Chapter 1.

The depth marker is cleared when the machining depth is reset.

Step 1:

Step 2:

Acknowledging workpiece location check

The control has reported a workpiece location error.

The location malfunction message can be cleared by location repeat, e.g. by

Blowing-off the workpiece support.
Raise the lifting device and then lower again.

Preconditions:

Safety doors closed and locked.
Drives and media switched on.
"Setup" machine mode is active.
"Acknowledge" HMI screen is opened.

Confirming location check as OK

Step 1:

Confirming location check as NOK

Step 1:

Acknowledge test grip of loader

Whenever the workpiece data register of the machine is faulty, the control sends a request to the loader to execute a test grip.

While the Z slide of the machine is at its loading/unloading position, the loader enters the work area with an empty gripper and carries out its "test grip" (workpiece presence check). Subsequently, the loader moves back to its home position.

Finally, the operator must acknowledge the process in the machine control.
