Automatic program start

Application

With the Automatic program start function you define a specific time at which the control will start to execute an NC program, such as a warm-up program for the machine. No machine operator needs to be present.

Requirements

  • The function must be enabled by your machine manufacturer.
  • In the machine parameter autoStartEnabled (no. 100701), the machine manufacturer defines whether an automatic program start is possible.

  • Machine is switched on
  • No NC program is currently running on the machine
  • If a program is already running at the specified time, the control will not execute an automatic program start.

  • Machine is prepared for the NC program (e.g., correct workpiece preset is active)
  •  
    Tip

    HEIDENHAIN recommends activating the workpiece preset in the NC program.

Description of function

Use this function to execute NC programs and pallet tables.

If you select the Automatic program start button, the control opens the Automatic program start window.

The Automatic program start window

The control offers the following possibilities in the Automatic program start window:

1

Defining the date and time

2

Selecting an NC program via a selection window

3

Activating automatic program start

4

Deactivating automatic program start

If an automatic program start is active, the control displays an icon in the information bar.

Notes

 
Warning
Caution: hazard to the user!
If automatic program start is active, the machine starts an NC program on its own and moves the axes. There is an increased risk of injury on machines without housing.
  1. Clearly indicate on the machine whether Automatic program start is active
  2. If necessary, restrict access to the machine
 
Notice
Caution: Significant property damage!
If automatic program start is active, the machine starts an NC program without a machinist and moves the axes. Collisions can occur if the machine was not set up correctly, or if there have been changes in the meantime. There might be no machinist present in order to abort program run.
  1. Set up the machine appropriately for such machining, e.g.:
    • Install the correct workholding equipment
    • Measure the tools used in the NC program and stock them in the magazine
  2. Optimize the NC program for automation, e.g.:
    • Automatic presetting
    • Activating the most recently set preset
    • Calling the correct workholding equipment
  • In the machine parameter closeDialogOnOK (no. 100702), the machine manufacturer defines whether the control closes the Automatic program start window after activation.
  • In the machine parameter useLastStartData (no. 100703), the machine manufacturer defines whether the control offers the last defined settings when opening the Automatic program start window.
  • Ensure that the tools being used have sufficient service life remaining. If necessary, define a replacement tool.
